The terminals for the 24 V external supply both input and
output are as follows:
– 1 = +24V unswitched
– 2 = 0V unswitched
– 3 = +24V switched
– 4 = 0V switched
Screws tightening torque: 1.5 Nm.

Unswitched and switched power supply
The unswitched 24
V power supply (also known as non-
switched) on X1.2 and X1.4 provides
power to the general electronics of the Control Unit. The switched 24
V power supply on
X1.1 and X1.5 supplies power for the two digital outputs (DI0 and DI1).
For a complete explanation of the unswitched and switched 24 V supplies and their
limitations, please read the FAQ at the following link:
