Frequently Asked Questions (FAQ)

1. What type of discrete input is supported by the 170BDI34600?
   This module supports 24 VDC sink-type inputs, meaning it accepts signals sourced from devices with a common negative.

2. Does the 170BDI34600 provide per-channel isolation?
   The module uses optical isolation to separate the input signals from the internal logic, ensuring noise immunity.

3. Is this module compatible with Modbus TCP/IP systems?
   Yes, when used with a compatible communication adapter (e.g., 170ENT11001), it can integrate into Modbus TCP/IP networks.

4. How are the inputs grouped electrically?
   Inputs are typically grouped in banks of 8, each with a shared common, improving wiring organization.

5. Can I wire 2-wire sensors directly to the 170BDI34600?
   Yes, provided the sensors are compatible with 24 VDC sink input logic.

6. Are the input statuses visible without software?
   Yes, each group of 8 inputs has an associated LED indicator showing the ON/OFF status.

7. Can I hot swap this module without shutting down the system?
   Yes, Momentum I/O modules including the 170BDI34600 support hot swapping in compatible bases.

8. How does the module receive its power?
   Power is delivered through the base backplane, connected to the communication adapter and system power.

9. Is filtering available to debounce signals from mechanical switches?
   Yes, input signal filtering is typically managed through the controller or communication adapter.

10. What happens if a signal wire disconnects or shorts?
    Input-level diagnostics at the module can detect signal faults, reported through the control system.
