ProSense Universal Transmitter Signal Conditioner models SCU-2501,
SCU-2502 and SCU-2503 are single input devices that accept PNP, NPN,
TTL, NAMUR, and custom special trigger current or voltage level frequency.
The SCU-2501 and SCU-2502 models support relay output with the
SCU-2502 having two independently triggered relay outputs. The SCU-2501
and SCU-2503 provide a mA (sourcing or sinking) or voltage output. The
SCU-2503 is the only unit with a frequency output allowing for frequency/
frequency conversion. They feature a plastic slim-line housing, integral 35mm
DIN rail mounting adapter, and removable screw terminals. The detachable
SCU-PDM2 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.

~ 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-PDM2. This device contains no DIP-switches or jumpers. Units must
be mounted on a DIN rail according to DIN 60715
SAFETY INSTRUCTIONS
Receipt and unpacking
Unpack the device without damaging it. The packing should always follow the device until it has been perma-
nently mounted. Check at the receipt of the device to ensure the type corresponds to the one ordered.
Environment
Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock, as well as rain and heavy
moisture. If necessary, heating in excess of the stated limits for ambient temperatures should be avoided by
way of ventilation. All devices can be used for Measurement / Overvoltage Category II and Pollution Degree
2. The module is designed to operate safely at an altitude of 2000m or less.
Mounting
Mounting and connection of the device should comply with national legislation for mounting of electric
materials, i.e. wire cross section, protective fuse, and location. Descriptions of input / output and supply
connections are shown in this installation guide and on the side label. The following apply to hazardous
voltage-connected devices:
The max. protective fuse is 10A. A power switch shall be easily accessible and close to the device. The power
switch shall be marked as the disconnecting unit for the device.
UL installation requirements
Use 60/75°C copper conductors only.
For use only in pollution degree 2 or better.
Max. ambient temperature ................................................. 60°C (140°F)
Wire size ............................................................................ AWG 26-14
UL file number, SCU-2501, SCU-2502 & SCU-2503....... E197592
The device is an Open Type Listed Process Control Equipment. To prevent injury resulting from accessibility
to live parts the equipment must be installed in an enclosure.
Calibration and adjustment
During calibration and adjustment, the measuring and connection of external voltages must be carried out
according to the specifications of this installation guide. The technician must use tools and instruments that
are safe to use.
Cleaning
When disconnected, the device may be cleaned with a cloth moistened with distilled water.

* For low signal levels with input trigger level hysteresis below 100 mV / 0.1 mA it is
recommended to use shielded cables with correct grounding, to avoid false triggering due to
induced EMC.
