Foxboro P0973CND FCP Termination Module I/A Series

Product Description

The Foxboro P0973CND is a field termination assembly engineered to interface field wiring directly with Foxboro Field Control Processors (FCPs) within the I/A Series Distributed Control System. It provides a structured and reliable connection point for routing both analog and discrete signals from field instruments into the control layer.

As a passive termination unit, it does not require independent power for signal handling, which simplifies installation and improves overall system reliability. The module is designed for continuous operation in demanding industrial environments, with robust mechanical construction to withstand vibration, temperature variation, and long-term use.

In some system configurations, the P0973CND is supplied as part of an integrated FCP assembly, which explains references to onboard processing and memory. However, in its standalone role, it functions strictly as a signal termination and distribution interface.

FAQ

Q: Does the P0973CND require a power supply?
A: No. In its standard form, it is a passive termination module and does not consume power.

Q: Why do some listings mention CPU and memory?
A: Those specifications refer to configurations where the module is integrated into an FCP assembly. The standalone termination unit itself does not include active processing.

Q: What type of wiring does it support?
A: It uses screw terminals compatible with 14–22 AWG wires, suitable for typical industrial field wiring practices.
