Description
Honeywell CC-PDOD51
Technical Specifications 32 sink-type digital output channels; rated 24VDC field output; single channel continuous current 0.1A; backplane 5VDC power supply from rack carrier; operating temperature 0℃~60℃; storage temperature -40℃~85℃; humidity 5%~95% non-condensing; 1000VAC galvanic isolation between channel and backplane; built-in self-resetting PTC short-circuit protection; support pulse, lock and PWM output mode.
Functional Features It converts the digital control logic of the controller into 24VDC sink drive signal. Each channel has independent short-circuit protection. It supports configurable FAILOPT safe state when fault occurs. It diagnoses wire break and load fault of each channel and uploads alarm. It supports hot swap, and can form redundant configuration with CC-TDOD61 redundant IOTA.
Application Scenarios Drive of small solenoid valves and interlocking relays in chemical plant; control of boiler burner interlock coil and baffle actuator; on-off control of auxiliary pump and fan auxiliary loop; sequential control output of packaging and conveying equipment; digital drive of fire and gas auxiliary alarm equipment.
Performance Parameters PTC short-circuit protection responds rapidly and limits channel current when overload occurs; the channel isolation circuit prevents fault from spreading to backplane bus; the output mode switching response is stable; the fault diagnosis of each channel is independent.
Material Composition FR4 flame retardant PCB with G3 conformal coating. Gold-plated backplane connector. Flame retardant PC front panel. Power MOSFET output tube and PTC self-recovery fuse. ESD protection diode on each output channel.
Structural Characteristics Series C single-slot vertical IOM card. Front panel with power, run, communication and group fault LED indicators. Elastic locking buckles on both sides. Fool-proof structure, matched with TDOD51 non-redundant IOTA or TDOD61 redundant IOTA. Passive heat dissipation.
Working Principle C300 controller sends digital switch command to CC-PDOD51 through backplane bus. The module controls the on-off of each channel open-drain MOS tube. The 24VDC power supply of the field load is provided by the supporting TDOD series IOTA base. The module detects the current of each output channel in real time. When short circuit or open circuit occurs, it triggers PTC protection and reports fault information to the controller.
Installation Requirements Vertically installed in Series C I/O rack and matched with TDOD51 or TDOD61 termination base. Field 24VDC load cables are separated from analog signal cables. The load power supply of the channel is provided by the IOTA base. Cabinet grounding resistance ≤4Ω.
Usage Notes The module is sink output, confirm the polarity of the load circuit before wiring. Do not use it to directly drive high-power loads exceeding single-channel current rating. Before online replacement, bypass the related interlock logic to prevent misoperation.
