XM-441 Expansion Relay Module

The XM® 441 Expansion Relay Modules provide four additional relays to any XM measurement module or to an XM-440 Master Relay Module. These are not intelligent XM modules, and they do not consume node addresses on DeviceNet™ buses. These modules simply extend the circuitry of their host modules. Configuration is provided through the host module by simply replacing the host module’s virtual relays with physical relays.
