Product Manual Excerpt

Features 32 Points - Four isolated groups of 8 points each Positive/Negative Logic Compatibility Proximity switch compatible Input filter selectable* - 1mS or 10mS One input configurable as interrupt* * These features are available for all IC697 Programmable Logic Controllers (PLC). They may not be available when this module is used with other types of PLCs. See the applicable Programmable Controllers Reference Manual for details. Functions The 24 Volt DC Positive/Negative Logic Input Module provides 32 input points in four isolated groups of eight points each. The input current-voltage characteristics meet IEC standard (type 1) specifications. LED indicators which give the ON-OFF status of each point on the logic (PLC) side of the circuit are included at the top of the module. The module is mechanically keyed to ensure correct replacement with a similar type in the field. I/O references are user configurable without the use of jumpers or DIP switches on the module. Configuration is done using the configuration function of the MS-DOS or Windows programming software running on Windows 95 or Windows NT over Ethernet TCP/IP or through the SNP port. The Programming Software configuration function is installed on the programming device. The programming device can be an IBM) XT, AT, PS/2) or compatible Personal Computer.

Block Diagram for IC697MDL653 Input Characteristics This input module is designed to have both positive and negative logic characteristics in that it sinks or sources current from the input device to the user common. The input device is connected between the power bus and the module input as shown above. This module is compatible with a wide variety of input devices, such as: Pushbuttons, limit switches, selector switches; Electronic proximity switches, both 2-wire and 3-wire. In addition, inputs on this module may be directly driven by any IC697 PLC voltage compatible output module. The input circuitry provides sufficient current to ensure reliable operation of the switching device. Input current is typically 10mA in the ON state, and can accept up to 2 mA leakage current in the OFF state without turning on. 3-wire proximity switches are easily applied, since they provide low voltage drop in the ON state and low leakage current in the OFF State. 2-wire proximity switches derive their power from the signal connections; thus both the ON state voltage and the OFF state leakage current are higher than for 3-wire devices. This module is designed to be compatible with many such 2-wire devices; however each device type must be carefully evaluated for compatibility in both the ON and OFF states. To determine compatibility with a specific proximity switch, find the ON state characteristics of the switch in the diagram shown below. If that point falls to the left of the input load line, the ON state characteristics are compatible. As an example, the ON state requirements of a compatible proximity switch of 3mA at 5 volts drop are shown below. OFF state compatibility is assured if the proximity switch leakage is less than 2mA with a module input voltage of 5 volts or less.

Configuration is on a module, not per point basis; all points have the same filter time. See the applicable Programmable Controllers Reference Manual for detailed information. Interrupt When used with the IC697 CPU, input point A1 may be configured to cause a CPU interrupt. Configuration allows the CPU to be interrupted on either the rising or falling edge of the signal transition. Interrupt response is not affected by input filter time selection. Refer to the applicable Programmable Controllers Reference Manual for detailed information. Module Mechanical Keying This module includes a mechanical key that prevents inadvertent substitution of one module type for another in a given slot. The key fits a uniquely shaped area on the board below the connector. Each module has a key packaged with it. When the module is first installed, the key latches onto the backplane center rail. When the module is extracted, the key remains in the center rail, configuring the slot to accept only identical module types. If it is necessary to change the module location in the rack after the key has been latched onto the center rail of the rack, the key can be removed by pushing it upward to unhook the latch while pulling it off the rail. It may then be reinserted onto the module and the module inserted into the rack in the desired location. Note that in an IC697 PLC rack only the power supply can be placed in the leftmost rack position, and slot 1 (adjacent to the power supply) must always contain a CPU (in rack 0 - the CPU rack), or a Bus Receiver Module (in an expansion rack). Field Wiring The module is wired as shown in Figure 3. Since each group of eight inputs is isolated from the others, a wire from the power source to the power input terminal (10, 20, 30, or 40) for each group is required (power input terminals for each group are not connected inside the module).

Module features referenced in the following procedures which are common to all IC697 I/O modules are illustrated in the following figure. a43855 HINGED DOOR TERMINAL BOARD JACKSCREW JACKSCREW CORD TIE CLEAT STRAP CORD TIE CLEAT STRAP CORD TIE CORD TIE Figure 4. I/O Module Features 1. Turn off power before removing or installing terminal boards. Open the hinged door on the module to access a jackscrew which holds the terminal board securely in place. The detachable field wiring terminal board can now be removed from the module by turning the jackscrew counter-clockwise until it is fully disengaged. 2. To remove the terminal board, grasp the top of the terminal board and swing it outward. Caution Do not use the hinged door to remove the terminal board. The hinged door could be damaged if this is done. 3. The terminal board is designed to accept wire sizes from AWG #22 (0.36 mm2) through AWG #14 (2.10 mm2). It is important that when using AWG #14 (2.10 mm2) wire for wiring all points, that a maximum insulation diameter of .135 inch (3.43mm) not be exceeded. To ensure proper connection, two wires may be terminated on any one terminal only if both wires are the same size. 4. The terminal board is designed to accept a maximum of (40) AWG #14 (2.10 mm2)wires. If AWG #14 (2.10 mm2) wires are to be used, then wire markers should be placed at least 8 inches (203 mm) from termination end to provide sufficient space for the hinged door to close. 5 24 Volt DC Positive/Negative Logic, 32-Point Input Module GFK-0379F Discrete Input Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F JACKSCREW a43747 WIRE BUNDLE CABLE TIE CLEAT DO NOT PULL ON DOOR Figure 5. Removal of I/O Terminal Board 5. After completing connections to all modules in a rack, the wire bundle must be secured. To ensure that the wire bundle is secured properly, it is recommended that a cable tie be wrapped around the wire bundle and tightly secured through the cable tie cleat located at the lower right corner of the terminal board. For extremely large wire bundles, additional cable ties should be used. 6. A door label insert is included with each module to indicate circuit wiring information and provide space to record user circuit wiring identification. A slot is provided on the hinged door to allow for insertion of this label. If the label is difficult to insert, crease the scored edge before insertion. The outside label has a color coded stripe to allow quick identification of the module voltage type (blue: low voltage; red: high voltage). 7. After field wiring is completed, the terminal board should be securely fastened to the rack by inserting the terminal board strap (attached to each module) into the small rectangular slots in the bottom card guide grill on the rack. This strap not only secures the terminal board to the rack, it also provides a way of identifying the wired terminal board with its correct mating rack slot location. 8. For adequate module ventilation, it is recommended that at least a 6 inch (152mm) clearance be allowed above and below the rack grill. Wire bundles should not obstruct the rack grill work. Removing an I/O Module The instructions below should be followed when removing an I/O module from its slot in a rack. Grasp the board firmly at the top and bottom of the board cover with your thumbs on the front of the cover and your fingers on the plastic clips on the back of the cover. Squeeze the rack clips on the back of the cover with your fingers to disengage the clip from the rack rail and pull the board firmly to remove it from the backplane connector. Slide the board along the card guide and remove it from the rack.
