Siemens XTRI-D Dual Input Module

The Siemens XTRI-D is an intelligent dual-input interface module for monitoring two sets of normally open or normally closed dry contacts on the SLC. It includes 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 device occupies one loop address but responds independently to each input. Also known as P/N S54370-B2-A1.
