Description

Product Description

The IC695ALG708 analog output module is designed for the GE Fanuc / Emerson PACSystems RX3i platform, providing eight non-isolated output channels for precise control of field devices. Each channel can be configured independently via software to deliver either voltage or current signals, eliminating the need for hardware jumpers and simplifying commissioning.

Built for demanding control environments, the module supports standard industrial output ranges and delivers consistent performance with fast update cycles and integrated diagnostics. It requires an external 24 VDC supply for field-side operation and installs directly into the RX3i Universal Backplane.

FAQ

Q: Can voltage and current outputs be used simultaneously?
A: Yes, each channel is independently configurable, allowing mixed signal types within the same module.

Q: Does the module require an external power supply?
A: Yes, a 24 VDC external supply must be connected at the terminal block for output operation.

Q: Is the module isolated?
A: No, this is a non-isolated module, so proper grounding and signal reference design are important.

Q: What happens to outputs during a fault condition?
A: The module can be configured to either maintain the last output value or transition to a predefined safe state.
