The GE IC693ACC338 is an electrical PLC module known as the "Input Simulator Module" in the GE 90-30 series PLC system. This module is used for testing and simulation purposes during the development and maintenance of PLC systems.

Key features of the IC693ACC338 Input Simulator Module include:

- The module provides simulated input points to the PLC system, allowing users to test and simulate input conditions without the need for actual field devices.

- It offers 32 simulated input points, which can be activated or deactivated through software commands or wiring configuration.

- The IC693ACC338 supports a variety of input types, including discrete and analog signals, to replicate different input conditions.

- The module allows users to simulate specific signal patterns, frequencies, and values for testing and troubleshooting purposes.

- It can be easily configured and integrated into the GE 90-30 PLC system, typically within the PLC rack.

By using the input simulator module, PLC engineers and technicians can simulate various input conditions and test the response of the PLC system, allowing them to validate program logic, troubleshoot issues, and optimize system performance without the need for actual field equipment.
