Honeywell CLIOP831A CentraLine Mixed Panel Bus I/O Module

Basic Overview

Full I/O Channel Configuration

1. 12 Binary Inputs (BI)
    
   Collect digital dry contact signals: air flow switches, filter differential pressure, door status, fire alarm contacts
2. 8 Analog Inputs (AI, 16-bit high precision)
    
   Supported signal ranges: 0–5V, 1–5V, 0.4–2V, 4–20mA (250Ω built-in resistor)
    
   For temperature transmitters, pressure/humidity sensors, flow transmitters
3. 8 Analog Outputs (AO)
    
   Standard output: 0–11VDC, drive proportional valves, VAV actuators, frequency converters
4. 6 Relay Outputs (RO)
    
   Relay rating: 24VAC/DC, 0.5A per channel
    
   Control fans, water pumps, cooling/heating contactors, lighting circuits

Electrical Parameters

• Power supply: 24VAC ±20% / 21–30VDC
• A/D resolution: 16 bits
• Input scan cycle: 50ms
• Built-in overvoltage & short-circuit protection for all channels
• Panel Bus communication via dedicated backplane bus to EAGLE master controller
• Hex DIP switch on side to set module bus address

Terminal & Mechanical Features

1. Wiring: Standard screw terminal blocks for field wiring
2. Auxiliary terminal expansion: Only allows XS830/XS831 auxiliary terminal packs on the top side only (CLIOP830A supports top + bottom)
3. Hot-swap support: Module plug/unplug without cutting cabinet main power
4. Status indicators: Independent LED for power, communication fault, each I/O channel state
5. Dimension: W110 × H61.1 × D54.4 mm, weight ~0.6kg
6. Mounting: Standard 35mm DIN rail, vertical/horizontal installation allowed

Core Advantages

1. All-in-one mixed I/O layout, one module covers digital input, analog acquisition, proportional regulation and relay switching, reduces cabinet module quantity
2. High-precision 16-bit analog sampling, stable HVAC closed-loop temperature/humidity control
3. Fail-safe logic: Relay outputs switch to pre-defined safety state when bus communication drops
4. Modular pluggable design, fast replacement without re-wiring field sensors/actuators
5. Full EMC filtering, anti-interference for building automation cabinet environments
6. CE, cUL safety certified, complies with EN 60730 building control standards

Communication & System Matching

• Bus: Honeywell proprietary Panel Bus, dedicated to CentraLine EAGLE series BMS controllers
• Programming software: ComfortPoint Open Studio for logic configuration, PID parameter setup, alarm linkage
• Multi-module expansion: Multiple CLIOP series modules can be stacked on one EAGLE controller bus

Typical Application Scenarios

• Commercial building HVAC BMS (office malls, hotels, hospitals)
• VAV air conditioning unit monitoring & proportional valve regulation
• Chiller, cooling tower, water pump group automatic control
• Ventilation, smoke exhaust fan interlock control
• Indoor temperature, humidity, CO₂ concentration monitoring system
• Centralized building energy management & equipment status remote monitoring
