A 4-channel temperature input module for the u-remote system, the module detects cable breaks and over\/under-range values via individual channel diagnosis. Automatic 50 Hz to 60 Hz interference suppression and an adjustable conversion time of 36 to 240 ms are included. Sensors connect via 2-wire, 3-wire or 4-wire PUSH IN terminals to support a wide range of RTD wiring configurations. The module electronics supply connected sensors from the input current path (UIN). Compatible with all u-remote fieldbus head stations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailable in stock\u003c\/strong\u003e — ships within 3 days after payment.\u003c\/p\u003e\n\u003ch3\u003eProduct overview\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; font-size: 12px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px 8px; width: 40%;\"\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px 8px;\"\u003eWeidmüller Interface GmbH \u0026amp; Co.
