222: Model code for relay-type output base

G01: Hardware revision version

Technical Specifications

Backplane powered; 16-channel field terminal layout with pluggable relay positions

Single relay contact rating: AC250V/5A max load

Galvanic isolation between backplane circuit and field load circuit: 1000VAC

Operating ambient: -40℃ ~ +70℃, 5%~90%RH non-condensing; hot-swap supported

Net weight: approx 0.33kg

Interface & Communication Layout

Rear connector inserts rack backplane for internal bus connection with matched personality card

Front terminal block for field load wiring and external relay installation

Working status displayed via indicator LEDs on paired upper DO module

Core Functions

Mechanical carrier and wiring base for corresponding digital output personality module

Distribute internal control signals to each field channel via installed plug-in relays

Concentrate field cables for solenoid, pump and fan control loads

Feed back channel abnormal signals to matching I/O card for system fault diagnosis

Application Scenarios

Boiler auxiliary interlock output, turbine auxiliary solenoid drive in thermal power plants; petrochemical on-site valve switching control, spare replacement for old Ovation I/O cabinets.

Operation & Maintenance Notes

Separate field control wiring from high-current power cables to avoid interference

Replace failed plug-in relays directly without removing base module

Check terminal screw tightness during regular maintenance inspection
