Honeywell CC-PDOB01 Digital Output 24V Module

The Honeywell CC-PDOB01 is a 32-channel 24V bussed digital output card designed for Experion C300 I/O systems. It provides discrete switching control for field devices by driving 24 VDC loads up to a maximum continuous voltage limit of 30 VDC.

Electrical Performance and Output Characteristics

Each of the 32 output channels delivers a typical on-state voltage of 24 V at a 0.5 A load current, maintaining low off-state leakage current below 0.5 uA. Under no-load conditions, the off-state indicated voltage reaches a maximum of 3.3 VDC, dropping to 0V VDC max under load. The module features dynamic switching response times with turn-on and turn-off delays not exceeding 10 ms.

Isolation and System Protection

To safeguard controller electronics against electrical transients and ground loops, the module incorporates robust galvanic isolation rated at 1500 VAC RMS or ±1500 VDC. This isolation barrier separates internal backplane logic from external field-side wiring loops.
