Essential details：1440-RMA00-04RC XM-440 Master Relay Module Allen Bradley

The XM-440 Master Relay module combines four relay outputs with XM bus master capabilities to provide remote, shared, and voted relay operation for distributed XM measurement modules. It is a member of the Allen-Bradley™ XM® Series, a family of DIN rail mounted condition monitoring and protection modules that operate both in stand-alone applications or integrate with Programmable Logic Controllers (PLCs) and control system networks.
The XM-440 offers four high power relays suitable for use in most protection applications. The module also supports connecting one or two XM-441 Expansion Relay modules, providing a total of up to 12 relays.
The module provides “A Out of B” voting logic. This logic, defined uniquely per relay, can be applied to an alarm status broadcast from XM measurement modules located anywhere on the XM bus. The XM-440 can also send a trigger event to a group of XM measurement modules when one or more of its relays are activated, causing the XM measurement modules to collect their triggered trend data.
The XM-440 module is configurable over a DeviceNet network or using a serial connection to a PC or laptop. For list of configuration parameters for the XM-440, refer to Chapter 3.
