~ WARNING ~
This device is designed for connection to hazardous electric voltages. Ignoring this warning can result
in severe personal injury or mechanical damage. To avoid the risk of electric shock and fire, the safety
instructions of this guide must be observed and the guidelines followed. The specifications must not be
exceeded, and the device must only be applied as described in the following. Prior to the commissioning
of the device, this installation guide must be examined carefully. Only qualified personnel (technicians)
should install this device. If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Until the device is mounted, do not connect hazardous voltages to the device. The following operations
should only be carried out on a disconnected device and under ESD safe conditions: General mounting,
connection and disconnection of wires.
Do not open the front plate of the device as this will cause damage to the connector for the
display / programming front SCU-PDM1. This device contains no DIP-switches or jumpers. Units must
be mounted on a DIN rail according to DIN 60715

Universal Signal Conditioners
ProSense Universal Transmitter Signal Conditioner models
SCU-1400, SCU-1600 and SCU-3100 are single input devices
that accept milliampere, voltage, RTD, thermocouple or poten-
tiometer inputs. The SCU-1400 and SCU-1600 models support
a selectable single analog output. The SCU-1600 and SCU-3100
provide two programmable relay outputs. They feature a plastic
slim-line housing, integral 35mm DIN rail mounting adapter,
and removable screw terminals. The detachable SCU-PDM1
programming / display module (purchased separately) is required
for unit configuration. The programming / display module may
remain affixed for operational display of input and output values.

Application Example - Voltage Input to
Current and/or Relay Output
A level sensor with 0-5 VDC output needs to be connected to a 4-20
mA and/or digital inputs input on a PLC. The sensor measures
fluid level between 0 and 60” in a tank. When using the SCU-1600
or SCU-3100, low and high alarms will be set at 5” and 55” respec-
tively with a 3” hysteresis and 5 second on delay set for each alarm.
In the event of a sensor error, both relays will hold in their current
state when the error occured. Relay switching will work as follows:
