Frequently Asked Questions (FAQ)

1. What type of input configuration does the 170BDM34600 support?

   The module supports 24 VDC sink-type inputs, suitable for sourcing-type sensors.

2. What output type does the module provide?

   It provides 24 VDC source-type outputs, capable of directly driving solenoids, relays, or indicator lamps.

3. Can the module be used for safety-critical inputs?

   While not safety-certified, it can monitor safety devices if redundancy and external safety logic are employed.

4. Does this module support hot-swapping?

   Yes, the 170BDM34600 supports hot-swap replacement when installed in a Momentum system with appropriate base.

5. Is signal debouncing available for the inputs?

   Input filtering is handled by the controller or communication adapter configuration, not within the module itself.

6. What is the max current capacity of the output section?

   Each output can handle up to 0.5 A, with a total module output capacity of 8 A.

7. How are the input/output points isolated?

   Inputs and outputs are optically isolated from the control logic to reduce noise and prevent damage.

8. Can I connect both inductive and resistive loads to the outputs?

   Yes, both types are supported; inductive loads should include flyback diodes for protection.

9. What is the recommended fuse rating for the output channels?

   Use 0.5 A fast-blow or resettable fuses per output for optimal protection.

10. How does the module communicate with the PLC CPU?

    Communication is handled via the Momentum base and communication adapter, such as Ethernet or Modbus TCP.
