PR Electronics 5105B Ex-isolated Driver PR Electronics 5105B intrinsically safe isolated driver is a safety barrier for current signals transmitted to I/P converters and displays mounted in hazardous area. The 5105B 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 5105A 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.
