More Information

Overview Manuals Compatibility Environmental Ratings Monitoring & Control Installation

Features:

  • Latched, pulsed, or pulse-width-modulated channel action
  • No output-current gap during redundant switchover
  • One protective series fuse for each group of eight outputs
The 32 source outputs of 8C-PDODA1 51454472-175 share a bussed return, but their commanded behavior is assigned channel by channel. A point can remain latched, issue a timed pulse, or operate with pulse-width modulation according to the control strategy.

A redundant pair transfers without an output-current gap, allowing the connected load path to remain energized through switchover. FAILOPT separately determines whether each point holds its last state or moves to its configured safe state.

Protection is organized on the DO IOTA, where a series fuse serves each bank of eight channels. The output module can be removed or inserted under power while the field wiring remains on the termination assembly.
The Honeywell 8C-PDODA1 51454472-175 Digital Output Module is listed as Active / Available from OEM. Apter Power can assist with availability inquiries and access to available Honeywell documentation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Termination hardware choices:

  • Non-redundant base: 8C-TDODA1 is the coated 9-inch IOTA for a single 8C-PDODA1 51454472-175 path.
  • Redundant base: 8C-TDODB1 is the coated 12-inch IOTA used when redundant module support is required.
  • Switchover: The redundant arrangement is specified with no output-current gap during transfer.
  • Relay extension: 8C-SDOX01 can extend the 24 VDC output module through the supported relay arrangement.

Electrical and service boundaries:

  • Channel load: Each 8C-PDODA1 51454472-175 output is rated to 100 mA maximum.
  • Switching response: Turn-on and turn-off time is specified at 10 ms maximum.
  • Temperature range: Operation is specified from 0 to 60 °C, with storage from -40 to 85 °C.
  • Service access: Removal and insertion under power is supported, while DO IOTA fuses protect groups of eight channels.

Per-channel control:

  • Source outputs: 8C-PDODA1 51454472-175 switches positive 24 VDC output paths for connected field loads.
  • Latched action: Individual channels can retain a commanded state until the control strategy changes it.
  • Timed action: Pulsed and pulse-width-modulated behavior can be assigned independently by channel.
  • Safe state: FAILOPT directs each output to hold its last value or shed to a configured safe value.

Field supply selection:

  • Common return: All 32 outputs on 8C-PDODA1 51454472-175 share the same bussed return.
  • System excitation: The output bank can use the Series 8 system supply as its 24 VDC source.
  • External excitation: A separate 24 VDC field supply permits system-to-field galvanic isolation.
  • IOTA wiring: Termination wiring determines whether field outputs reference system power or the external source.
Description
Process loads connected to 8C-PDODA1 51454472-175 receive positive 24 VDC switching from 32 source-type channels that share a common return. The module can drive devices such as solenoid valves and interposing relays within the published per-channel load boundary.

Field excitation may come from Series 8 system power or a separate 24 VDC supply. An external supply enables system-to-field galvanic isolation, with the IOTA wiring establishing the reference used by the entire output bank.

The coated 8C-TDODA1 nine-inch IOTA is used for a single output path, whereas 8C-TDODB1 provides a twelve-inch redundant base. Where dry relay contacts are needed, the supported 8C-SDOX01 relay extension adds that interface to the digital-output assembly.

Each channel is rated for up to 100 mA, with a 30 VDC maximum load voltage, 5 uA maximum off-state leakage, and 10 ms maximum turn-on or turn-off time. Together these limits define the load devices and switching response appropriate for the module.
