1. Product Overview

2. Electrical Specifications

• Channel layout: 8 fully galvanic isolated universal analog input channels, Quad-Bus SUB8 architecture, software configurable per channel for 4–20mA DC current / 0–5V / 0–10V DC voltage input (core upgrade from G01 single 4–20mA only)

• Backplane power: +5VDC & ±12VDC powered via SUB8 rack backplane; typical power consumption ≤4.5W

• Isolation rating: 1000VAC channel-to-backplane isolation; G50 variant adds multi-stage TVS surge absorption circuit for anti-lightning & cabinet power clutter interference

• Loop parameter: 2-wire/3-wire transmitter loop supply supported; max loop resistance: 900Ω(@4–20mA); voltage input high impedance ≥1MΩ

• Measurement performance: Basic accuracy ≤0.1%FS; full 8-channel scan refresh ≤3ms; built-in per-channel open-circuit, over-range, short-circuit diagnostic, fault codes uploaded to DCS automatically

• Signal filtering: Digital low-pass filter adjustable via Ovation software to suppress field EMI noise

3. Mechanical & Environmental Data

• Form factor: Standard hot-swappable plug-in SUB8 rack module, unified dimension:260mm×100mm×25mm, same mechanical outline as all other Q-series I/O modules

• Operating ambient: -40℃ ~ +70℃; storage temp: -45℃ ~ +85℃; humidity 5%~95%RH non-condensing; G50 passes enhanced power-industry EMC certification for coal-fired thermal plant site

• Net weight: approx 0.36kg

4. Front Panel LED Definition & Core Features

LED Indicator Description

• POWER(Green): Normal backplane power feed

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

• CH1~CH8 Individual LED: Lights up when valid analog signal detected on corresponding channel

• FAULT(Red): Alarm for channel open/overrange/onboard hardware failure

Main Functional Highlights

1. Online hot-swap: Module replacement without rack power shutdown, no impact on adjacent I/O cards

2. G02 universal input: Software switch current/voltage mode per single channel without field wiring modification

3. G50 reinforced protection: Extra surge & transient suppression for harsh power/chemical field installation

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

5. Flexible configuration: Input range, filter coefficient, upper/lower alarm threshold editable on Ovation Developer software

5. Typical Industrial Application
