Description

PR5104B

Supply voltage and safety barrier for 2-wire transmitters mounted in a hazardous area.
Safety barrier for analog current / voltage signals from a hazardous area.
1 : 1 or signal conversion of analog current / voltage signals.

The 20 factory-calibrated measurement ranges in the 5104B can be selected by the internal DIP-switches without the need for recalibration. Special measurement ranges can be delivered.
PR5104B 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 / voltage transmitter or as a 2-wire transmitter.

Mounted vertically or horizontally on a DIN rail. By way of the 2-channel version up to 84 channels per meter can be mounted.
NB: 5104B is recommended as I.S. barrier for 5331D, 5333D, 5334B, 5343B, 6331B, 6333B, and 6334B.
