Principais características

1- or 2-channel version
3- / 5-port 3.75 kVAC galvanic isolation
Driver for Ex / I.S. area
20 programmable measurement ranges
Universal supply by AC or DC


Safety barrier for current signals transmitted to I/P converters and displays mounted in hazardous area.
Safety barrier for analog current / voltage signals transmitted to hazardous area.
1 : 1 or signal conversion of analog current / voltage signals.

Mounted vertically or horizontally on a DIN rail. By way of the 2-channel version up to 84 channels per meter can be mounted.


The 20 factory-calibrated measurement ranges in the 5105B can be selected by the internal DIP-switches without the need for a recalibration. Special measurement ranges can be delivered.

PR5105B is based on microprocessor technology for gain and offset. The analog signal is transmitted at a response time of less than 25 ms.

Inputs, outputs, and supply are floating and galvanically separated.
