Frequently Asked Questions (FAQ)

1. What types of loads can the 8C-PDODA1 drive?

   It can drive DC loads such as solenoids, relays, LED indicators, and other discrete actuators requiring 24 V DC sinking output.

2. Is the module hot-swappable?

   Yes, it supports hot-swapping, allowing field replacement without interrupting system operation.

3. Does the module support redundant operation?

   Yes, it can be configured with redundant I/O modules for increased system reliability.

4. How many channels are available on this module?

   The module offers 16 independent digital output channels.

5. Can the module be used in hazardous environments?

   While the module itself is not intrinsically safe, it can be used in hazardous environments when installed with appropriate barriers and enclosures.

6. What kind of diagnostics are available?

   The module provides per-channel diagnostics including short circuit detection, open load monitoring, and overcurrent conditions.

7. Is configuration done through Honeywell software?

   Yes, configuration and commissioning are handled via Honeywell’s Control Builder and Experion PKS tools.

8. What is the maximum output current per channel?
