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

The Allen-Bradley 1440-RMA00-04RC, also known as the XM-440 Master Relay Module, is designed to provide remote, shared, and voted relay operations for distributed XM measurement modules. With four integrated relay outputs and the ability to expand by connecting XM-441 expansion modules, the 1440-RMA00-04RC is a versatile solution for industrial machinery monitoring and protection, reducing downtime and providing critical health assessment of machinery.

Advantages:

• Provides remote and shared relay control for distributed measurement modules.

• Expandable with additional XM-441 expansion modules to increase relay capacity.

• Supports DeviceNet communication for integration with existing industrial systems.

General Info

• Manufacturer: Allen-Bradley

• Model Number: 1440-RMA00-04RC

• Type: Master Relay Module

• Relay Type: DPDT (2 Form C), four integrated relays

• Power Supply: 24V DC Class 2/SELV

• Communication Protocol: DeviceNet and RS-232

• Compatibility: Compatible with distributed XM measurement modules

Features

• Four Integrated Relays: The 1440-RMA00-04RC module includes four DPDT relays, each with two sets of contacts, providing flexibility for managing industrial control operations.

• Expandable Capacity: Connect one or two XM-441 expansion modules to increase the total number of available relays to 8 or 12, supporting larger or more complex systems.

• DeviceNet Communication: Utilizes DeviceNet for communication, with a configurable I/O Poll Response message to optimize space within the scanner input tables. The communication rate is automatically set by the bus master to 125, 250, or 500 Kbps.

• Flexible Relay Operation: Each relay can be configured for normally energized (failsafe) or de-energized (non-failsafe) operation, and supports latching or non-latching modes with adjustable time delays from 0 to 25.5 seconds in 100 ms increments.

• Environmental Durability: Designed for demanding industrial conditions, with conformal coating for printed circuit boards and extensive environmental ratings for temperature, humidity, vibration, and shock resistance.
