Bul. 937C Universal Temperature Converter Installation Instructions
The Universal Temperature Converter must only be operated by trained personnel in
accordance with this handbook.
The protection of operating personnel and of the system is only ensured if the devices
are used in accordance with their intended purpose. Any other type of operation than
that described in this manual places the safety and functionality of the devices and
systems connected to them in question.
The devices may only be installed, connected, and adjusted by electrical professionals
outside the hazardous area.
If faults cannot be elimina ted, the devices must b e taken out of operation and protected
from being placed in service again inadvertently. Tampering with or making changes to
the devices is dangerous and therefore not permitted. They render the warranty void.
The responsibility for the adherence to local safety standards lies with the operator.
Bul. 937C Universal Temperature Converter Installation Instructions
Overview
The devices of the Bul. 937C IS Barriers, Isolators and Converters are used to transmit signals
between field devices and the process control system or control.
The Bulletin 937 devices are suitable for connection to field devices in the hazardous area. The
field current circui
not intrinsically safe circuits. The devices thus represent an electrical isolation between the
hazardous area and the secure area.
Further information (e. g. certificates, the data sheets for the Universal Temperature Converter and
the operating instructions can be found on www.ab.com.
ts of these devices are intrinsically safe and are galvanically isolated from the
The temperature converter is used
for temperature measurement.
Resistance temperature detectors,
thermocouples, potentiometers or voltage
sources can be connected to the inputs of
the converter.
The Universal Temperature Converter
converts the input signals into proportional
current signals. The output signals can, for
example, be for-warded to displays or
analog inputs of the process control system.

Connection
The slip-off terminals significantly simplify connection and
construction of switching cabinets. They allow
free exchange of the unit when service is needed.
The terminals can be screwed on, are self-opening, and have
generous connection room for a wire diameter of up to 2.5 mm²
and coded plugs, so that leads cannot be confused.
Intrinsically safe field circuits are connected to the blue terminals
1 to 6 of the Universal Temperature Converter. These may be
conducted using DIN
