The maximum cable length that can be connected is 30 m.
Note
Ensuring the function of digital inputs
An open input is interpreted as "low".
To enable the digital inputs (DI) to function, terminal M2 must be connected.
This is achieved by using one of the following measures:
1. Providing the ground reference of the digital inputs
2. A jumper to terminal M
Note: This removes isolation for these digital inputs.
Note
If the 24 V supply is briefly interrupted, then the digital outputs are deactivated during this time.
