Core Key Features

1. Standard Ovation rack pluggable design, automatic slot address identification via backplane bus, no manual DIP switch setting.

2. Full channel overcurrent, short-circuit, surge transient protection per output loop.

3. Real-time fault diagnosis for open-circuit, overload, module power abnormal, fault status uploaded to Ovation HMI & historian server.

4. Hot-plug maintenance: replace faulty module online without stopping related control logic operation.

5. CE & EMC industrial certification, meets IEC anti-interference standard for heavy industrial site environment.

2. Detailed Technical Specification

2.1 Channel & Electrical Parameters

• Output channel: 16 isolated digital output channels per single module

• Rated output drive: DC24V field loop drive, passive/active discrete output configurable by Ovation engineering software

• Single channel maximum load current: 0.5A per point; total module rated output load ≤8A

• Isolation grade: ≥1000VAC dielectric isolation between each output channel and internal backplane control circuit to eliminate ground loop interference

• Internal power supply: +24VDC powered from cabinet rack PDM power distribution unit

2.2 Environmental Working Spec

• Operating ambient temperature inside control cabinet: 0℃ ~ +60℃

• Storage & transportation temperature: -40℃ ~ +85℃

• Working humidity: 5%~95%RH non-condensing; avoid corrosive gas, dense oil mist and continuous liquid splash environment

• Anti-vibration: complies with industrial cabinet vibration standard for long-term power plant on-site running

2.3 Mechanical & Indicator Definition

• Structure: Standard Ovation vertical plug-in electronic card, install on matched dedicated I/O base

• Front panel LED status indicators:

  • PWR(Green): Module normal power supply

  • RUN(Green): Module in normal communication & working status

  • FAULT(Red): Module hardware fault / bus communication loss / channel overload alarm

  • CH Status LED: Individual indicator for each output channel on/off status

• Flame retardant plastic housing, compact industrial anti-vibration structure

3. Installation & Wiring Instruction

1. Installation Steps: Cut off target slot backplane power optional (support hot swap), align module gold finger with base slot, insert firmly until card locks in place; system automatically recognizes module ID after power on via backplane electronic ID.

2. Field Wiring: Connect field actuator load wiring to corresponding base terminal per channel definition; separate control cabinet internal power wire and field load cable for anti-interference layout.

3. System Configuration: Add module I/O points in Ovation engineering software, set output type, load parameter and fault alarm logic, download configuration to rack CCM controller.

4. Troubleshooting Guide

1. PWR LED off: Check rack base 24VDC power supply and base wiring; replace base or module for hardware damage.

2. RUN LED off, FAULT red on: Backplane bus communication failure, re-plug module or inspect rack backplane.

3. Single channel no output: Check field wiring short/open circuit, channel overload; module internal channel circuit damage needs spare replacement.

4. Random channel overload alarm: Reduce field load current within module rated specification.

5. Application Scope

• Power plant: Boiler auxiliary solenoid valve control, fan/feed pump auxiliary contact interlock, ash removal equipment on-off control

• Petrochemical: Pipeline cut-off valve discrete control, tank level interlock switch output

• Water industry: Pump group start-stop control, dosing valve switch control
