CC-PAOH01

Product Introduction

CC-PAOH01 is Honeywell C-series 16-channel HART analog output module for C300 PKS system, outputs 4–20mA control signal to field positioning valve, actuator and smart positioner with HART digital communication function.

Model Interpretation

CC = C300 I/O series; PAOH = Process Analog Output with HART; 01 = 16-channel standard specification.

Technical Specifications

Power: Backplane 24VDC supply, typical power consumption 4.7W

Channels:16-channel 4–20mA analog output, HART7 compatible

Output precision: ±0.05%FS full scale; channel-backplane isolation 1500VAC

Working range: -40℃ ~ +70℃; UL/CE, ATEX Zone2 & Class I Div.2 approval

Interface and Communication Configuration

Front LED: Power, Healthy, HART status indicators; rear connects matched IOTA terminal base, all field control wiring wired on IOTA terminals; HART signal multiplexed on analog output loop.

Core Function

Receive control instruction from C300 CPU, convert digital command into 4–20mA analog signal to regulate field control valve opening.

HART communication enables remote reading of smart valve feedback, stroke fault and online parameter calibration of valve positioner.

Output short-circuit protection per channel to avoid internal circuit damage caused by field wiring failure.
