Voltage: -3 V to 30 V
Current input (typical):
10 mA at 24 V
With electrical isolation: Reference
potential is terminal M2
High level: 15 V to 30 V
Low level: -3 V to 5 V
1)
DI: digital input; M2: ground reference; M: electronic ground
Max. connectable cross-section: 1.5 mm² (AWG 14)
NOTE
An open-circuit input is interpreted as “low“.
Terminal M1 must be connected so that the digital inputs can function correctly.
The following solutions are possible:
1) The provided ground reference of the digital inputs, or
2) A jumper to terminal M (Important: electrical isolation for the digital inputs
is revoked as a result).
