GE Fanuc IC695ALG704

Product Overview: GE Fanuc IC695ALG704 Analog Output Module

The GE Fanuc IC695ALG704 is a four-channel analog output module specifically designed for use within the PACSystems RX3i programmable automation controller (PAC) system. It delivers precise, configurable analog signals to field devices, including actuators, control valves, and indicators, supporting both voltage and current output modes. This module is intended for high-performance industrial automation applications where reliable and accurate analog signal generation is required.

Each of the four output channels on the IC695ALG704 can be independently configured for different output ranges. The module is non-isolated, meaning the outputs share a common reference, which is acceptable in many control environments where channel-to-channel isolation is not necessary. It is well-suited for environments requiring precise control feedback and stable analog output, such as process automation and instrumentation.
