1. Product Overview

2. Electrical Specifications

• Channel layout: 16 isolated digital output channels grouped in Quad-Bus architecture, solid-state transistor non-contact output design

• Rated field load: 24VDC dry/wet contact drive; single channel max continuous load current 0.5A, inrush surge current limited internally

• Backplane power supply: +5VDC & ±12VDC fed via SUB8 rack backplane; typical power consumption ≤3.9W

• Galvanic isolation: 1000VAC isolation between field output loops and internal Quad-Bus backplane for anti-EMI & surge suppression

• Per-channel protection: built-in overcurrent, short-circuit automatic cutoff protection; circuit fault diagnosed and uploaded to DPU

• Scan cycle: Full 16-channel command refresh ≤2ms, compatible with Ovation SOE event sequence recording function

3. Mechanical & Environmental Parameters

• Form factor: Standard plug-in SUB8 rack module, unified dimension:260mm×100mm×25mm; supports online hot-swap without rack power shutdown

• Operating ambient: -40℃ ~ +70℃; storage temperature: -45℃ ~ +85℃; humidity 5%~95%RH non-condensing, CE industrial EMC certified

• Net weight: approx 0.345kg

4. Front Panel LED Indicators & Core Features

LED Status Definition

• POWER(Green): Normal backplane power input

• RUN(Green): Healthy Quad-Bus communication with SUB8 master card

• CH1~CH16 individual LED: Illuminates when corresponding output channel is switched ON

• FAULT(Red): Alarm for channel short-circuit, over-load or onboard hardware failure

Key Functional Highlights

1. Hot-swap maintenance: Single card replacement online without affecting other I/O modules on same rack

2. Channel independent diagnostics: Short/open/overload fault reported to DCS for real-time system alarm

3. Redundant bus compatible: Fully works with redundant 3A99159G03 master cards for SUB8 dual-bus redundant configuration

4. Software configurable: Set fail-safe status (ON/OFF hold) and output delay filtering via Ovation Developer configuration software

5. Typical Industrial Application

• On-off control of boiler auxiliary fans, coal feeder, soot blower solenoid valves in thermal power plants

• Interlock control of shutdown valves, pump on-off contactors in refining & chemical process units

• Motor start/stop logic output and field status lamp driving for metallurgy and waste incineration DCS control
