1. Product Introduction

Note: G05 = fixed 12CH 0~5V voltage-only input definition; separate G50 suffix version: 3A99163G05G50 = factory enhanced anti-surge industrial upgrade for high EMI power plant cabinets.

2. Electrical Specifications

• Channel layout: 12 fully galvanic isolated analog input channels, SUB8 Quad-Bus architecture, fixed input range: 0 ~ 5VDC high-impedance voltage input only (no 4–20mA current support)

• Backplane power supply: +5VDC & ±12VDC powered via SUB8 rack backplane; typical power consumption ≤5.1W

• Isolation rating: 1000VAC channel-to-backplane galvanic isolation; G50 upgraded version adds multi-stage TVS lightning/transient surge suppression circuit

• Input impedance: ≥1.2MΩ per channel, no field loop power supply required (passive voltage sampling only)

• Measurement precision: Full scale accuracy ≤0.12%FS; full 12-channel scan cycle ≤3.5ms

• Built-in diagnostics: Per-channel open-circuit detection, over-range alarm, onboard hardware fault self-check, all fault status uploaded to Ovation DCS software automatically

3. Mechanical & Environmental Parameters

• Form factor: Standard hot-swappable plug-in PCB for SUB8 rack, unified outer dimension:260mm×100mm×25mm, identical mechanical size with all Q-series SUB8 I/O modules

• Operating temperature: -40℃ ~ +70℃; storage temperature: -45℃ ~ +85℃; ambient humidity:5%~95%RH non-condensing; G50 variant meets enhanced power-industry EMC & CE certification for coal-fired thermal power plant harsh environment

• Net weight: approx 0.38kg

4. Front Panel LED Definition & Core Features

LED Indicator Description

• POWER(Green): Normal backplane power feed

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

• CH1~CH12 LED: Illuminate when valid 0~5V analog signal detected on corresponding channel

• FAULT(Red): Activated by channel open/overrange or module internal hardware malfunction

Core Functional Highlights

1. Online hot-swap: Module replacement without rack power cut, no disturbance to other adjacent I/O cards in same SUB8 rack

2. Fixed-range design: Hardware-locked 0~5V input, no software range switching (differentiated from G02 universal mA/V model)

3. G50 reinforced option: Optimized PCB anti-interference layout plus extra surge components for high voltage interference site

4. Dual-redundant bus compatible: Fully applicable to redundant master card(3A99159G03) SUB8 redundant control system

5. Software configurable: Digital filter coefficient, upper/lower process alarm thresholds adjustable via Ovation Developer configuration tool

5. Typical Application Scenarios

• Thermal power plant: RTD/thermocouple temperature converter output signal collection, displacement transmitter voltage sampling, auxiliary equipment analog voltage monitoring

• Petrochemical plant: Potentiometer-type valve feedback signal, split converter output voltage acquisition

• Waste-to-energy & water treatment: Multi-channel temperature conversion voltage centralized acquisition
