Bul. 937
C Strain Gauge 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.
937 products are suitable for connection to field devices in the hazardous area. The field current
circuits of these devices are intrinsically safe and are galvanically isolated from the not intrinsically
safe circuits. The devices thus represent an electrical isolation between the hazardous area and
the secure area.
Devices can be used for signal transmission between field devices in the secure area and the
process control system or the control.
Resistance bridges, i. e. strain gauges,
load cells, force transducers, pressure
transducers, torque shafts or similar
devices, can be connected to the input of
the converters .
The 937CU-AISTR-DC1 converts the
input signal into a proportional output
current, which can be forwarded e. g. to a
display unit or an analog input of the
process control system or control. By
means of the two relay outputs.
Two different, freely parameterisable trip values of the input signal can be monitored.

instructions for the Bul. 937 family) can be found on our Internet page www.ab.com.
