9.7 G60, Terminal Module TM31
Note
Ensuring the function of digital inputs
An open input is interpreted as "low".
Terminal M1 must be connected so that the digital inputs (DI) can function.
This is achieved through one of the following measures:
1. Also route the reference ground of the digital inputs.
2. A jumper to terminal M. (Note: This removes the electrical isolation for these digital
inputs.)
X530: 4 digital inputs

Connector
Max. connectable cross-section: 1.5 mm²
DI: digital input; M2: ground reference; M: Electronics ground
