Features
vice is suitable for the connection of resistance thermometers
– Configurable 3-way temperature transducer
and remote resistance-type sensors in 2, 3 and 4-wire con-
– Configurable via DIP switches for Pt 100 and Pt 1000
nection technology.
(IEC 751)

– Extended functionality configurable with free software
voltage signal.
– Approval for Ex-zone 2 (nA)
The device can either be configured via DIP switches or, with
extended functionality, via the S port using the software (FDT/ – Screw or spring-cage connection can be provided
DTM).
The device supports fault monitoring.
WARNING: Correct usage in potentially explosive areas
The module is a category 3 item of electrical equipment. It is absolutely vital to follow the instructions provided
here during installation and observe the information in the "Safety regulations and installation notes".
Make sure you always use the latest documentation.

DIN rail connector (TBUS), 5-pos., for bridging the supply voltage, can be
snapped onto NS 35/... DIN rails according to EN 60715
DIN rail power supply unit, primary-switched mode, slim design, output:
24 V DC / 1.5 A
Eight MINI analog signal converters with screw connection method can be
connected to a control system using a system adapter and system cabling
with a minimum of wiring and very low error risk.
MINI analog multiplexer, generates one analog output from 8 analog input
signals, for MINI analog module with screw connection.
