TIP The Expansion Relay module can be connected to the module to provide
additional relays. Refer the XM-441 Expansion Relay Module User Manual

When the relay is configured for non-failsafe operation, the relay is
normally de-energized.
When the relay is configured for failsafe operation, the relay is normally
energized, and the behavior of the NO terminals is inverted.
