Honeywell CC-PCF901 (PN:51405047-175) is a ControlNet fiber optic communication adapter module for Experion PKS C300 controller. It converts electrical ControlNet signal to optical signal to extend communication distance and isolate electrical interference, supporting redundant fiber network configuration. It effectively avoids surge and electromagnetic noise interference in high-voltage and high-vibration industrial environments. It serves as fiber media converter between C300 and ControlNet network, supports hot swap and network fault diagnosis, widely used in power plants and petrochemical projects for long-distance ControlNet backbone communication.

Honeywell CC-PCNTOX (PN:51308307-175) is a ControlNet communication interface module for Experion PKS C300. It connects C300 controller to the ControlNet redundant control network, realizing real-time deterministic communication between controller, I/O modules, operator stations and other network nodes. It supports dual redundant ControlNet ports, built-in network traffic monitoring and communication fault alarm. With hot-swap capability, it guarantees uninterrupted network communication, commonly used as the core network card of C300 DCS controller in continuous process industries.

Honeywell CC-PDIL01 (PN:51308388-175) is a 32-channel low-side digital input module of Experion PKS Series C I/O. It collects 24VDC discrete contact status signals from field limit switches, relay contacts and equipment status feedbacks. Each channel adopts group isolation design and signal filtering function to filter out field noise and chatter signals. It converts on/off status into digital data and transmits to C300 controller, with channel fault detection. It supports hot swap and redundant installation, used for equipment status monitoring and interlock logic signal acquisition in chemical, power and pulp & paper plants.

Honeywell CC-PDOB01 (PN:51405043-175) is a 16-channel digital output relay module for Experion PKS C300 DCS. It outputs dry contact relay signals to drive field relays, solenoid valves and equipment interlock circuits. Relay contacts support on/off switching of field circuits, each channel has relay status feedback and fault diagnosis function. It supports hot swap and redundant configuration, with contact overcurrent protection. It is widely used for emergency trip, equipment start/stop and safety interlock control loops in petrochemical and power process control systems.
