K120RTD

2 WIRE - LOOP POWERED TRANSMITTER FOR PT100 AND NI100 PROBES

General Description

The K120RTD instrument converts a temperature signal read by a PT100 (EN 60 751) or
NI100 probe with connection by 2, 3 or 4 wires into a signal normalised in current for 4 20

-

mA loop (2 wires technology).
The module's main features are:
