FAQ
Frequently Asked Questions (FAQ)
Q1: What is the function of the ABB 07DI90-S module?
A1: The 07DI90-S is a digital input module with 8 channels designed for safety-related applications. It detects signal states and differentiates faults such as wire cuts and short circuits using dual-channel processing.
Q2: How is the module connected to the control system?
A2: The module connects to the central controller (07 KT 94-S) via the CS31 system bus. Electrical isolation is maintained between the system bus and the input channels.
Q3: What types of sensors can be connected to the input channels?
A3: The module is intended for 24 V DC safety-related sensors. These must be supplied from the same power rail (UP) as the module to ensure accurate signal state differentiation.
Q4: How are module addresses configured?
A4: The address is set using a DIL switch located beneath the module’s cover. Switches 3 to 7 represent binary address bits with a range from 0 to 31.
Q5: How are errors detected and indicated?
A5: The module distinguishes between internal and external errors. External faults like wire cuts or overvoltage are indicated via a flashing red LED, while internal faults cause the red LED and all channel LEDs to stay lit.
Q6: What happens during startup?
A6: Upon power-up, the module performs a self-test. The red error LED lights up for approximately 10 seconds, then flashes until the module is adopted into the CS31 bus cycle.
Q7: How should unused inputs be handled?
A7: Unused input channels must be pulled up to +24 V using two resistors (680 Ω and 5.6 kΩ in series) to prevent fault indication due to floating inputs.
Q8: What is the required installation method and mounting position?
A8: The module can be DIN rail mounted or screwed directly into the control cabinet. It must be installed vertically with terminals at the top and bottom to allow proper convection cooling.
