Siemens XTRI-R Single Input Module (with relay)

The Siemens XTRI-R is an intelligent single-input interface module with an addressable Form C relay, letting you monitor a dry contact and control a relay at the same address. It features ISOtechnology dual isolation for NFPA 72 Class X (Style 7) survivability, a tri-color status LED, and configurable wiring: isolator mode or polarity-insensitive wiring in non-isolator mode using SureWire. The relay and the input can be controlled as separate functions by the FACP. Also known as P/N S54370-B1-A1.
