GFK-0385F Analog Input System, High Level, 16 Channels 2 Analog Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 57-2 Functions The High Level Analog Input subsystem for the Programmable Logic Controller (PLC) accepts analog inputs of up to 10 volts full scale, or 4 to 20 milliamp current loop signals. These inputs are converted to digital form for use by the CPU or other controllers accessing analog inputs via the VME backplane. Converted data is presented as 2 s complement (sign + 15 bits). The basic converter is 14 bits resolution (1 part in 16384); an oversampling and averaging technique further enhances this resolution. Inputs are protected against transient and steady-state overvoltage conditions. Analog inputs use %AI references in the programmable controller. A maximum of 8K words of %AI memory is currently available in the programmable controller. Each input channel uses one word (16 bits) of %AI memory. Field wiring is made to a removable terminal board and the module is mechanically keyed to ensure correct replacement with a similar module 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.

Expander Module 3 Analog Input System, High Level, 16 Channels GFK-0385F Analog Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 57-3 High Level Analog Input System Modules Three module types are included in the High Level Analog Input subsystem: a Base Converter module, a Current Expander module, and a Voltage Expander module. A typical subsystem will use a Base Converter module and (if required) one or more expander modules. Base Converter module - catalog number IC697ALG230 This module has eight differential inputs and an expansion port. Each input can be individually configured for either voltage or current. Each of the input channels also has individual user scaling. On-board load resistors are included for normal input current ranges up to 40 mA. If other current ranges or different resolution is required, external resistors may be used. Standard system configurations for 10 volts and 4 to 20 mA are available. These, and other lower input ranges, can be scaled to engineering units with the user scaling feature. Expander Modules Up to seven Expander modules can be daisychained off the Base Converter module to increase the number of inputs of the total subsystem up to a maximum of 120. The Base Converter module accepts any mix of the two Expander module types. A common user scaling factor applies to all inputs on each Expander module, however each Expander module may be individually scaled as required. Current Input Expander module - catalog number IC697ALG440 The Current Expander module has 16 current inputs each accepting up to 20 mA. Voltage Input Expander module - catalog number IC697ALG441 The Voltage Expander module has 16 differential voltage inputs each accepting up to 10V signals.

Module features referenced in the following procedures which are common to all IC697 I/O modules are illustrated in the following figure. a43855 Figure 7. 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 mm) through AWG #14 (2.10 mm). It is important that when using AWG #14 (2.10mm) 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 (2.10mm) wires. If AWG #14 (2.10mm) 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. 7 Analog Input System, High Level, 16 Channels GFK-0385F Analog Modules August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F
