The input and output are galvanically isolated from each other. It is designed for the connection of fire detectors, smoke detectors, temperature sensors, etc.\u003c\/p\u003e\n\u003cp\u003eThe detector's increased current range and the higher accuracy allow for differentiation between normal operation, fire alarm, lead breakage and short circuit currents in the safe area. In many cases they may also be used for controlling I\/P converters. A separate power supply with auxiliary power is not required.\u003c\/p\u003e\n\u003cp\u003eDue to the input voltage limiting of 24 V, the maximum voltage output is 21 V.• The isolation of power loops for the control of positioner, I\/P converters etc. A current source is connected to the safe area terminals. • The isolation of a current signal from fire detectors or similar sensors. In this case, a voltage source can be connected to the safe area terminals.\u003c\/p\u003e\n\u003cp\u003eA specific measurement current across a passive sensor can be measured in the safe area with a series resistor (min. 50 ohm). When a voltage supply is used, the measuring resistor can also provide current limitations.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eApproved with the IU2055 zone monitor unit\u003c\/li\u003e\n\u003cli\u003eOutput EEx ia IIC\u003c\/li\u003e\n\u003cli\u003eDevice installation permissible in zone 2\u003c\/li\u003e\n\u003cli\u003ePolarity reversal protected\u003c\/li\u003e\n\u003cli\u003eAccuracy 1%\u003c\/li\u003e\n\u003cli\u003eEMC acc. to NAMUR NE 21\u003c\/li\u003e\n\u003cli\u003eUp to SIL2 acc. to IEC 61508\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Kidde","offers":[{"title":"Default Title","offer_id":57567008457077,"sku":"GBX2000","price":481.76,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/1216\/0612\/files\/GBX2000.jpg?v=1789142311","url":"https:\/\/wmestore.co.uk\/products\/kidde-barrier-gbx2000","provider":"WME","version":"1.0","type":"link"}
