– 2 = 0V unswitched
– 3 = +24V switched
– 4 = 0V switched
• Screws tightening torque: 1.5 Nm.
• The cable glands have a diameter of 20 mm
• Wiring dimensions:
– 0.25 ... 2.5 mm

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:
