The CC-PDOB01 is a bussed 24VDC digital output module built for the Honeywell Experion Series C I/O family. It delivers reliable 24V output signals to control process equipment, solenoid valves, and interposing relays. Furthermore, high-energy output support reduces the number of external components needed in each output loop.
The module pairs with two IOTA base assemblies. Specifically, CC-TDOB01 serves non-redundant, 9-inch configurations, while CC-TDOB11 supports redundant, 12-inch layouts. Therefore, engineers can select the base that matches cabinet space and availability requirements.
The CC-PDOB01 offers 32 output channels in a sourcing configuration. Load voltage ranges from 15 to 30 VDC maximum. On-state voltage is typically 24 V at a load current of 0.5A. Meanwhile, off-state voltage stays at 0 VDC max, with 3.3 VDC max indicated under no-load conditions.
Current handling follows defined limits. Under no short condition, each channel carries 0.5A, each group of eight channels handles 4A, and the module totals 6A. With one shorted channel, the per-eight-channel limit drops to 3A. Moreover, with two shorts present, that limit falls to 1.5A, while the module total remains 6A.
Isolation and timing parameters suit demanding plants. Galvanic isolation reaches 1500 VAC RMS or ±1500 VDC, protecting the control system from field transients. Turn-on and turn-off times are 10 ms maximum. Additionally, off-state leak current stays at 5.0 µA max, and output voltage equals source voltage minus 150 mV maximum.
The CC-PDOB01 carries notable diagnostic and control features. Extensive internal diagnostics ensure data integrity, and optional redundancy keeps outputs available during module failure. Besides, direct and reverse output support adds wiring flexibility, and FAILOPT behavior lets each channel hold the last value or shed to a user-defined safe value. Latched, pulsed, or pulse-width modulated output modes work per channel.
The CC-PDOB01 occupies a standard Series C rack slot and weighs about 0.7 kg, simplifying installation and replacement. Its field-isolated design separates outputs from the Series C power system when an external 24V supply feeds the loop. Meanwhile, the bussed architecture shares a common return across all outputs, which simplifies field wiring.
Fuse-less short circuit protection stands out as a key benefit. When a channel shorts, internal circuits detect the fault and remove power from that field connection. The affected channel stays de-energized until the short is repaired, and no fuses blow. Therefore, maintenance teams avoid fuse replacement and reduce downtime.
Redundancy switchover introduces no output gap. Specifically, the module shows 0 ms gap at zero current during switchover, which suits continuous processes. However, this behavior applies to redundant configurations only.
First, confirm whether the application needs CC-TDOB01 or CC-TDOB11 before mounting the module. Next, seat the CC-PDOB01 firmly in its slot and secure the retaining screws. Then decide on field power excitation, choosing either the system supply or an external 24V source.
If using an external source, wire it to the field power terminals and verify galvanic isolation from the Series C power system. Furthermore, connect loads while observing the sourcing output type and common return. After wiring, configure FAILOPT per channel and set the output mode to latched, pulsed, or PWM as required.
Finally, test each channel with a known load and confirm the 10 ms response time. Also verify that short circuit protection clears after a simulated fault is removed.

Q: How many output channels does the CC-PDOB01 provide?
A: It provides 32 sourcing output channels with a bussed common return.
Q: Which IOTA models are compatible?
A: The module works with CC-TDOB01 for non-redundant 9-inch racks and CC-TDOB11 for redundant 12-inch racks.
Q: What happens when an output channel shorts?
A: Internal circuits detect the short and remove power from that channel without blowing fuses, so it stays de-energized until repaired.
Q: What is FAILOPT and how does it work?
A: FAILOPT sets per-channel failure behavior, letting the output hold the last value or shed to a user-configured safe value.
Q: How is the module shipped?
A: Orders ship via Fedex, UPS, or DHL, with antistatic protection and a cardboard box.
