Product Overview
The Allen-Bradley 1440-REX00-04RD functions as a high-performance XM-441 expansion relay module. It expands the capacity of any XM measurement module or the XM-440 master relay module by adding four independent relays. This integration enables users to configure complex wired alarms or initiate ad-hoc industrial processes based on real-time data. The host module manages all logic, latching, and time delays for the unit.

Frequently Asked Questions
Q: Can I use the 1440-REX00-04RD with non-XM systems?
A: No, this module is specifically engineered for the Allen-Bradley XM series measurement and master modules.
Q: How do I resolve relay interference issues?
A: Always ensure signal lines utilize shielded cables to ground out external electrical noise and harmonics.
Q: What is the benefit of the failsafe mode?
A: The failsafe (normally energized) mode ensures that the relay triggers if power is lost, providing critical safety for alarm systems.
Q: Can this module operate in high-temperature environments?
A: It must be housed in a protective cabinet with adequate airflow; excessive heat may degrade the printed circuit board over time.
Selection Guide
Choose the 1440-REX00-04RD if you need to expand your existing XM system alarm capacity. Verify that your host module supports the XM-441 expansion protocol before installation. Ensure your power supply provides a clean 24V DC to maintain optimal relay contact longevity.
