XF821A Module | Honeywell Analog Input for CIPer 50 Systems

Product Description

The Honeywell XF821A is a Pluggable Panel Bus Analog Input Module designed for the Excel 800 and CIPer™ 50 systems. It collects analog signals—such as temperature, humidity, and pressure—from field sensors and transmits them to the controller for real-time data processing and automation control.

This module’s pluggable design allows the electronic unit to be easily removed from its terminal base (XS821-22), simplifying installation and maintenance. In addition, the pre-wiring capability reduces downtime during system upgrades or replacements. Its compact form and robust signal accuracy make it ideal for building automation, HVAC, and energy management applications where consistent environmental control is essential.

Moreover, the XF821A integrates seamlessly with Honeywell’s Panel Bus architecture, ensuring reliable communication, precise signal conversion, and long-term operational stability.
