If jumpers are not properly selected,
12 Vdc / 30 mA are not available on ter-
minal 3 to power the sensor.
Example of Connection for linear input Volt and mA
+12 V
30 mA
For signals 0….10 V.
Comply with polarity.
+12 V
30 mA
For signals 0/4….20 mA with three-wire sensor.
Comply with polarity:
A= Sensor output
B= Sensor ground
C= Sensor power
For signals 0/4….20 mA with external power of
sensor.
Comply with polarity:
A= Sensor output
B= Sensor ground
+12 V
30 mA
For signals 0/4….20 mA with two-wire sensor.
Comply with polarity:
A= Sensor output
C= Sensor power supply
Serial Input
RS485 Modbus RTU communication.
Relay Q1 Output
Capacity 5 A / 250 V~ for resistive loads.
NB: see graphic next page.
Relay Q2 output for UR484802
Capacity 5 A / 250 V~ for resistive loads.
To select Q2 as relay output, remove jumpers JP5 and
JP7 as indicated in the gure (in the gure is shown
default conguration).
NB: see graphic next page.
Connecting a load without removing the
jumpers will permanently damage the
controller.
Relay Q2 output for UR484803 and UR484804
Capacity 5 A / 250 V~ for resistive loads.
NB: see graphic.
