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)
