The General Electric IC697ALG230 is an 8-channel high-level analog input module designed for the Series 90-70 Programmable Logic Controller (PLC) system. Serving as a base converter module, it provides high-precision signal processing for industrial automation applications. The module supports both voltage and current inputs, which are software-configurable per channel, and can be integrated with expansion modules to scale system capacity.

Features

  • 8 differential input channels.
  • Individually configurable for voltage (±10V) or current (4-20 mA) signals.
  • 16-bit resolution with oversampling and averaging techniques.
  • Compatible with IC697ALG440 (voltage) and IC697ALG441 (current) expander modules.
  • Mechanical keying for secure rack installation and error-free replacement.
  • User-defined scaling via programming software.

Applications

  • Process Monitoring: Captures data from temperature, pressure, and flow sensors.
  • Manufacturing: Provides precise feedback for motion control, CNC, and robotics.
  • Utilities: Manages flow, pressure, and chemical levels in water and power facilities.
  • Industrial Automation: Suitable for complex control systems requiring high-density analog input.

Installation Guidelines

  • Ensure the PLC rack power is disconnected before inserting or removing the module.
  • The module is mechanically keyed; ensure it is aligned correctly with the rack slot to prevent damage to the backplane pins.
  • Field wiring should be connected to the provided removable terminal board.
  • Maintain proper grounding practices to minimize EMI/RFI interference, especially when using long analog signal cable runs.
  • Use shielded twisted-pair cabling for analog inputs to ensure signal integrity.
  • Configure channel parameters using Proficy Machine Edition or legacy software (Logicmaster/VersaPro) via the CPU's SNP port or Ethernet.

FAQ

What is the primary function of the IC697ALG230?

It is an 8-channel base converter module that converts analog voltage or current signals into a digital format (2's complement) for processing by the Series 90-70 CPU via the VME backplane.

Can this module be expanded?

Yes, the IC697ALG230 can support up to 7 additional expander modules (IC697ALG440 or IC697ALG441) to increase the total number of analog inputs in the system.

How is the module configured?

Configuration is performed entirely through software. There are no physical jumpers or DIP switches on the module. Users define the input type, scaling, and memory references within the programming software.
