Frequently Asked Questions (FAQ)

Q1: What is the power supply requirement for the ABB 07DC91 module?
A1: The module operates with a rated supply voltage of 24 V DC.

Q2: How many input and output channels does the 07DC91 module have?
A2: It features 16 digital inputs, 8 digital transistor outputs, and 8 configurable I/O channels.

Q3: Are the outputs of the 07DC91 module protected against short circuits?
A3: Yes, the outputs are protected against overload and short circuit with automatic reactivation after fault removal.

Q4: Can the configurable I/O channels be changed during operation?
A4: The configurable channels are set through the user program and recognized at initialization; dynamic change during operation requires reinitialization.

Q5: How does the module indicate faults or errors?
