Honeywell 8C-PDOLA1 Series 8 Digital Output Module

The Honeywell 8C-PDOLA1, also cataloged as the 8C-PDOLA1 Digital Output Module, operates as a dedicated hardware component for 24 VDC sourcing discrete output control execution within Honeywell Experion PKS Series 8 platforms.

Hardware Specifications

Channel-to-Channel Isolation & Output Loop Performance

The 8C-PDOLA1 controls 32 discrete outputs via 24 VDC sourcing current switches designed to actuate solenoids, relays, and field interlocks. Incorporating channel-to-channel isolation and integrated line diagnostic circuits, the module detects open-circuit and short-circuit wiring conditions across field loops. The galvanically isolated output stages prevent inductive field switching transients from coupling into adjacent 4-20 mA HART loop protocol lines and system I/O buses.

Frequently Asked Questions

Q: Does the 8C-PDOLA1 support hot-swapping during active system operation?

A: Yes, the module can be inserted or removed under power without interrupting adjacent Series 8 I/O module communications or backplane bus integrity.

Q: What is the maximum load current capability per channel on the 8C-PDOLA1?

A: Each individual output channel supports up to 100 mA sourcing current at 24 VDC.

Field Installation Guidelines

1. Align the module housing with the designated slot guide rails on the Series 8 I/O terminal assembly base before seating backplane connectors.
2. Route field wiring bundles separately from high-voltage AC lines to minimize electromagnetic coupling into discrete output circuits.
3. Ensure the module mechanical latching mechanism is fully engaged to guarantee chassis grounding and prevent loose connection faults.
4. Verify cabinet temperature remains within the specified -20 to +60 deg C operating range to maintain normal output switching parameters.
