Overview

Core Technical Specifications

1. Channel & Signal Support

• Total 16 configurable analog input channels: 12 single-ended + 4 differential
• Compatible signals: 4–20mA 2-wire loop-powered HART transmitters, 0–5V / 1–5V / 0.4–2V DC voltage signals
• Native HART circuit matching, ensures stable bidirectional digital communication between module and smart instruments
• Per-channel independent miniature fuse, single-loop short circuit will not damage the whole board

2. Electrical Parameters

• Power supply: 24VDC control bus, power consumption ~2.46W
• Signal filtering: Built-in RC low-pass filter to suppress industrial frequency interference
• Test points reserved for each channel: 2mm measuring jacks for on-site signal calibration without disconnecting cables
• Terminal type: Screw clamp terminals, supports shielded instrument cable wiring, reserved shielding grounding terminals

3. Mechanical & Installation

• Size: 152 × 84 × 45mm; weight ~0.24kg
• Slanted inclined PCB design, good heat dissipation and convenient cable routing
• Rack screw fixed installation; the CC-PAIH02 I/O card directly plugs into the card slot on the IOTA board
• Cabinet internal IP20 protection grade

4. Environment & Certification

• Operating temperature: 0℃ ~ +60℃, storage: -40℃ ~ +85℃
• Humidity: 5%–95% RH non-condensing
• Certifications: UL508, CE, FM Class I Div.2 hazardous area approval

Key Functions & Features

1. Dedicated carrier base for CC-PAIH02 HART analog input card
    
   The I/O module is plugged onto the IOTA, all field wiring only connects to the terminal base, convenient for hot replacement of the acquisition card without removing field cables.
2. Integrated complete signal conditioning circuit
    
   Built-in anti-interference filter, loop current limiting, HART signal coupling circuit, no extra signal isolation board required.
3. Independent channel protection
    
   Each measuring point is equipped with a separate small fuse, fault isolation between channels, avoid single transmitter failure causing batch signal loss.
4. Convenient maintenance design
    
   Independent measuring test jacks for each channel, maintenance personnel can directly measure current/voltage signals on site; channel status indicator lights for quick fault positioning.
5. Non-redundant standard version
    
   Corresponding redundant model is CC-TAIX11; CC-TAIX01 applies to non-critical measuring loops to reduce cabinet cost.

Matching Combination

• IOTA Terminal Base: CC-TAIX01
• Supporting I/O Acquisition Card: CC-PAIH02 (16-channel HART analog input module)

Application Scenarios

• Petrochemical, chemical plant flow/pressure/temperature/liquid level HART transmitter wiring terminal
• Thermal power plant boiler auxiliary measuring point DCS cabinet
• Pharmaceutical, water treatment continuous process control system
• General industrial process monitoring with a large number of 4–20mA smart instruments
