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. Key Specifications: Type: Addressable dual-input monitor module with built-in ISOtechnology dual isolator Inputs: Monitors two N.O. or N.C. dry contacts and reports each input separately to the panel Wiring & Isolation: Configure as isolator or non-isolator; up to 252 isolators per loop; up to 30 devices between isolators (mixed mode) Status Indication: Tri-color LED for normal, trouble, alarm Operating Voltage: 13 to 32 VDC, low current draw Addressing & Service: Electronic programming and testing with the Siemens DPU field-device programmer; front access to programming port and terminals Mounting: 4-inch square, 2.25 in deep box or 3.5 in double-gang box; 5-inch square off-white faceplate included System Compatibility: Desigo Fire Safety and Cerberus PRO loops; X-series devices can be interspersed with H-series on the same loop except HLIM and SBGA-34. Accessories: DPU Field-Device Programmer / Test Unit – addressing and functional testing
