FAQ
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?
A5: A red LED on the front panel lights up to indicate faults such as short circuit, overload, or bus errors. Diagnostic information is also sent to the central unit.
Q6: What is the switching capacity of the output channels?
A6: Each transistor output can handle up to 0.5 A at 24 V DC. The total output group current should not exceed 4 A.
Q7: What type of electrical isolation is provided in the 07DC91 module?
A7: The CS31 system bus interface is electrically isolated from the power and signal sections of the module.
Q8: What are the module’s dimensions and weight for cabinet installation?
A8: The physical dimensions are 120 × 140 × 85 mm (W × H × D), and the operational weight is approximately 1.07 kg.
