X530: 4 digital inputs
Table 4- 19
Max. connectable cross-section: 1.5 mm²
DI: digital input; M2: ground reference; M: Electronics ground

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 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.)
