Honeywell CC-PDOB01 51405043-175 rəqəmsal çıxış G/Ç modulu

The Honeywell CC-PDOB01 (51405043-175) is described in the supplied material as a 32-channel, 24 V digital output module for switching external loads through discrete control signals. Its listed specifications include a maximum load voltage of 30 VDC, galvanic isolation rated at 1500 VAC RMS or +/-1500 VDC, and maximum turn-on and turn-off times of 10 ms. These values help define the module's output interface and switching characteristics.

Technical Specifications

Output Operation and Load Limits

The CC-PDOB01 is a bussed 24 VDC sourcing digital output module in Honeywell's Experion Series C I/O family. It supplies switched DC power to field devices such as solenoid valves and interposing relays. The outputs share a common return, so field wiring and load grouping must account for this shared electrical reference.

The documented maximum load current is 0.5 A per channel and 6 A per module. Outputs are grouped in four sets of eight channels, with a 4 A maximum per group under the specified no-short condition. These limits must be considered together when sizing the field power supply and connecting loads.

Protection and Configuration

The Series C specification describes electronic, fuse-less short-circuit protection. When a channel short circuit is detected, the module removes power from that field connection until the fault is corrected. The module also supports configurable output behavior on a per-channel basis, including holding the last value or changing to a configured safe value following the applicable failure condition.

Installation and Compatibility

The module is designed for the Honeywell Experion Series C I/O platform and uses an associated Input/Output Termination Assembly (IOTA). The documented assemblies include CC-TDOB01 for non-redundant use and CC-TDOB11 for redundant use. Confirm the installed IOTA, field-power arrangement, and system configuration before replacing an existing module.

Frequently Asked Questions

Q: How many field outputs does the CC-PDOB01 provide?

A: It provides 32 sourcing digital output channels. Each channel supports up to 0.5 A, subject to the documented group and total module current limits.

Q: What is the maximum load voltage?

A: The documented maximum load voltage is 30 VDC. The nominal output is 24 VDC, and the specified typical on-state voltage is 24 V at a load current of 0.5 A.

Q: Can the CC-PDOB01 be used in a redundant I/O configuration?

A: Yes. Honeywell's Series C I/O specification identifies the CC-TDOB11 as the redundant IOTA option. Redundant operation requires the appropriate termination hardware and system configuration; it should not be assumed from the output module alone.
