Terminal

Max. connectable cross-section: 0.5 mm

DI: Digital input, DO: digital output

Note

An open input is interpreted as "low".

The power supply and the digital inputs/outputs are optically isolated from the Control Unit.

Note

If a the 24 V supply is briefly interrupted, then the digital outputs are deactivated during this

time.
