Key features

3- / 5-port 3.75 kVAC galvanic isolation
Low response time
2-wire supply > 17 V in Ex / I.S. area
1- or 2-channel version
Universal supply by AC or DC


Power supply and Ex / I.S. safety barrier with 2-way HART® communication for 2-wire transmitters installed in the hazardous area.
Ex / I.S. safety barrier with 2-way HART® communication for supplied current transmitters installed in the hazardous area.
Signal isolator with low response time on analog current signals from the hazardous area.

Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighboring units, up to 84 channels can be mounted per meter.
PR5106B is recommended as Ex / I.S. safety barrier for 5335D and 6335D.


PR5106B primarily processes current signals of 4...20 mA.

PR5106B 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.

The output can be connected either as an active current transmitter or as a 2-wire transmitter.
