PR Electronics 5104B Ex Repeater / Power Supply PR Electronics 5104B intrinsically safe repeater is a power supply and safety barrier for 2-wire transmitters mounted in a hazardous area. The 5104B signal conditioner is based on microprocessor technology for gain and offset. The analogue signal is transmitted at a response time of less than 25 ms. 20 factory-calibrated measurement ranges in the 5104A can be selected by the internal DIP-switches without the need for recalibration. Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighbouring units, up to 84 channels can be mounted per meter. Features and Benefits • 1 : 1 or signal conversion of analogue current / voltage signals • 3.75 kV ac galvanic isolation • Loop supply > 17.1 V • Inputs, outputs and supply are floating and galvanically separated • Output can be connected either as an active current / voltage transmitter or as a 2-wire transmitter • Low response time • Universal supply by AC or DC • DIN Rail mounting (vertically or horizontally)
