HONEYWELL CC-PAIH01

Description

Functional Features:

• Per-channel configuration: Via Experion PKS Configuration Studio software
• Diagnostics: Per-channel wire break detection, overrange/underrange indication
• HART support: HART 7 passive mode (signal passes through to DCS; HART commands via separate module)
• Redundancy: Supports redundant I/O in Experion PKS FSC (Fault Tolerant Controller)

Performance Parameters:

• Sampling rate: 100 ms per channel (all channels)
• Common mode rejection: 120 dB at 50/60 Hz
• Operating temperature: 0°C to +60°C
• Dimensions: 25 mm × 120 mm × 160 mm (half-width I/O module)
• Weight: 200 g

Material Composition: FR-4 multi-layer PCB, gold-plated backplane connector, conformal-coated components, aluminum shield can

Structural Features: Half-width module for Experion PKS I/O carrier; 16 screw terminals on front for field wiring; LED indicators per channel (Power, Fault, Signal); backplane connector for carrier bus

Working Principle: The 4–20 mA signal from a field transmitter flows through the selectable burden resistor, creating a voltage drop (1–5 V at 250 Ω). The 16-bit A/D converter digitizes this voltage and sends the value to the Experion PKS controller via the backplane bus. Per-channel isolation amplifiers prevent ground loops between field devices.

Advantages:

• 16 channels per module reduces I/O carrier count
• Built-in burden resistor eliminates external shunt resistors
• High CMRR eliminates noise from long cable runs

Applicable Industries: Oil and gas, petrochemical, power generation, water treatment, pulp and paper

Installation Requirements:

• Insert into Experion PKS I/O carrier in the correct slot (address set via DIP switches or software)
• Use twisted-pair shielded cable for each 4–20 mA loop
• Terminate shields at controller end only (single-point grounding)

Usage Notes:

• Verify burden resistor setting matches transmitter requirements (250 Ω for most 4–20 mA devices)
• Perform zero and span calibration via Experion PKS software
• Do not exceed 30 VDC loop voltage (24 VDC supply + burden drop)
