Max. cross-section that can be connected: 1.5 mm²
Type: Screw terminal 1 (see Appendix A)
1) DI/DO: bidirectional digital input/output; M or GND: Electronic ground
Note
An open input is interpreted as "low".
Note
If a momentary interruption in the voltage occurs in the 24 V supply, the digital outputs will
be deactivated until the interruption has been rectified.
Notice
The digital outputs are only functional if terminals 1 and 6 are supplied with 24 V.
