Siemens XTRI-M Mini Module

The Siemens XTRI-M is a compact intelligent mini interface module for monitoring a normally open or normally closed dry contact on the SLC. It provides ISOtechnology dual isolation for True Class X (Style 7) survivability and can be configured as an isolator or wired in polarity-insensitive mode using SureWire. The device uses one address on the loop and is designed to mount inside a single-gang box behind equipment. Also known as P/N S54370-B4-A1. Key Specifications: Type: Addressable mini input interface module with built-in ISOtechnology dual isolator Input: Supervises and controls one N.O. or N.C. dry contact; reports status to the panel Wiring & Isolation: Isolator mode or non-isolator SureWire mode; up to 252 isolator-ready devices per loop; up to 30 non-isolated devices between isolators in mixed mode Operating Voltage: 13 to 32 VDC; low current draw (approx. 500 µA standby) Addressing & Service: Electronic programming and testing with the Siemens DPU field-device programmer Mounting: Single-gang switch box; compact form factor with flying leads for quick connections System Compatibility: Desigo Fire Safety and Cerberus PRO loops; X-series and H-series devices may be intermixed on the same loop except HLIM and SBGA-34. Accessories: DPU Field-Device Programmer / Test Unit – addressing and functional testing
