HONEYWELL CC-PDOB01 Central control module

Honeywell I/O Modules Overview

Honeywell offers a wide range of Input/Output (I/O) modules for its process control systems and industrial automation solutions. These modules provide the interface between field devices and the control system for data acquisition and control signal output. Honeywell I/O modules are designed to provide reliability, accuracy, and high performance to meet the needs of various industrial applications.

Product Detailed Description

• Function:

• Analog Input (AI) Modules: Receive signals from field analog sensors (such as temperature, pressure, flow sensors) and convert these analog signals into digital signals for processing by the control system.

• Analog Output (AO) Modules: Receive digital signals from the control system and convert these digital signals into analog signals for controlling field analog actuators (such as valve positioners, variable frequency drives).

• Digital Input (DI) Modules: Receive discrete signals from field digital devices (such as switches, proximity sensors) and transmit these signals to the control system.

• Digital Output (DO) Modules: Receive discrete signals from the control system and output these signals to field digital actuators (such as relays, solenoid valves).

• Special Function Modules: Some modules may offer special functions such as counters, frequency inputs, thermocouple/RTD inputs, etc.

• Features:

• High Reliability: Designed for stable operation in harsh industrial environments.

• High Accuracy: Provides accurate data acquisition and control signal output.

• Channel Isolation: Many modules offer electrical isolation between channels or between channels and the system to improve anti-interference capability.

• Hot-Swappable Capability: Some modules support hot-swapping, allowing replacement or addition while the system is running.

• Various Wiring Options: Offers various terminal blocks and connector options.

• Diagnostic Functions: Some modules have built-in diagnostic functions for monitoring module status and fault detection.

• Integration with Honeywell Control Systems: Seamless integration with Honeywell control systems such as Experion PKS.
