Microprocessor-based logic transmits the contact closure information in packets that are ordered and encoded, ensuring extremely robust and reliable transmission. Packets that are garbled, or packets out of sequence with transmission bit errors will not cause random changes of state in the FDC80R receiver unit relays.\u003c\/p\u003e\n\u003cp\u003eThe supervising function in the FDC80T transmitter allows for the detection of short and open circuit conditions, and normally open or normally closed contact inputs are supported. System faults are displayed via LED status indicators, and user-programmable summary fault alarm contacts are triggered in the FDC80R receiver unit. The FDC80R receiver is offered in both latching and non-latching relay configurations.\u003c\/p\u003e\n\u003cp\u003eExternal series and shunt resistors are included for each of the 8 contact input channels, for contact supervision.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMicroprocessor-based logic and latching relays in receiver unit eliminate random contact closure status in the event of loss of link or loss of prime operating power.\u003c\/li\u003e\n\u003cli\u003eDesigned to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line\/low-line voltage conditions, and transient voltage protection) of NEMA TS-1\/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.\u003c\/li\u003e\n\u003cli\u003eComFit standard form factor is interchangeable between stand-alone or rack mount use.\u003c\/li\u003e\n\u003cli\u003eStandard ComFit models are hot-swappable.\u003c\/li\u003e\n\u003cli\u003eInterchangeable between stand-alone or rack mount use – ComFit\u003c\/li\u003e\n\u003cli\u003eHot-swappable rack modules\u003c\/li\u003e\n\u003cli\u003eAutomatic resettable solid-state current limiters\u003c\/li\u003e\n\u003cli\u003eTransmits up to eight independent supervised or unsupervised dry switch or relay contacts over one optical fiber, or via a 2-wire RS-485 point-to-point copper circuit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf you are matching this to an existing installation, work from the FDC80RM1 part number rather than the description.\u003c\/p\u003e","brand":"Comnet","offers":[{"title":"Default Title","offer_id":57582804369781,"sku":"FDC80RM1","price":623.82,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/1216\/0612\/files\/FDC80RM1.jpg?v=1789646035","url":"https:\/\/wmestore.co.uk\/products\/comnet-transmitter-fdc80rm1","provider":"WME","version":"1.0","type":"link"}
