 2-Wire Programmable Transmitter
Key features

TC input
High measurement accuracy
Galvanic isolation
Programmable sensor error value
1- or 2-channel version


Linearized temperature measurement with TC sensor.
Amplification of bipolar mV signals to a 4...20 mA signal, optionally linearized according to a defined linearization function.

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


Within a few seconds the user can program PR6334A to measure temperatures within all TC ranges defined by the norms.

Cold junction compensation (CJC) with a built-in temperature sensor.

A limit can be programmed on the output signal.

Continuous check of vital stored data for safety reasons.
