Fig. 21: Module: mV temperature/mA input. Part number 734355
A module for the direct measurement of a pH value or redox potential via a coaxial cable and a
sensor signal from an mA 2-wire sensor, e.g. for chlorine, bromine or peracetic acid (PES).
mA interface:
n for use with ProMinent 2-wire transmitters and sensors with 2-wire mA interface.
n Processing of active mA signals, type of connector: current source.
n Driver voltage: 24 V DC.
n Max. current 50 mA.
n Input switches off at 70 mA.
n Protection against reverse polarity and overvoltage up to max. 30 V DC.
n Maximum cable length: 30 m, limited by the EMC specification.
2-wire control line for the connection of mA sensors to terminals XE5.2 and XE5.3
