The GE DS200RTBAG3AGC is not a PLC,but a relay terminal board(RTB)from the General Electric(GE)Mark V series.It is primarily used for signal transfer,distribution,and electrical isolation in industrial turbine control systems.It serves as a key interface component between control modules and field actuators.The following are its details:
I.Basic Information and Positioning
Brand:GE
Series:Mark V Speedtronic(designed for control systems for large rotating equipment such as gas turbines and steam turbines)
Function Type:Relay Terminal Board(RTB)
Core Function:Serves as an intermediate interface between control modules and external actuators such as relays,contactors,and solenoid valves,providing physical transfer,electrical isolation,and circuit protection for control signals,ensuring reliable transmission of control commands to field devices.
II.Core Functions and Technical Features
Signal Transfer and Integration Capabilities
Equipped with multiple high-density terminal blocks(typically two main terminal blocks),it supports centralized wiring of multiple relay output signals.It can connect field devices such as contactor coils,solenoid valves,and alarm indicators,simplifying control system wiring.Digital output modules compatible with the Mark V system(such as the DS200DTBC series)convert low-level logic signals from the control module(e.g.,24V DC)into high-voltage signals(e.g.,110V AC/220V AC)capable of driving external loads.
Electrical Isolation and Safety Protection
Built-in isolation circuitry provides electrical isolation between the control side(low-voltage and weak current)and the load side(high-voltage and strong current)(isolation voltage≥1500V AC),effectively eliminating ground loop interference and surges,and protecting the core control module from external high-voltage faults.
Some terminals incorporate integrated overcurrent protection components(such as fuses or current-limiting resistors)to prevent module damage caused by external load short circuits,enhancing system safety.
Industrial-Grade Reliability Design
Environmental Adaptability:Operating temperature range:-40°C to+70°C,it can withstand harsh industrial environments such as turbine rooms,characterized by high temperatures,vibration,and dust.Mechanical Structure:Utilizing a sturdy PCB design,compatible with Mark V system racks,terminals feature a locking latch structure to ensure long-term wiring stability.
Status Indicator:Power,communication,and fault status LED indicators provide intuitive feedback on module operating status,facilitating quick troubleshooting of wiring or signal faults.
III.Technical Parameter Overview
Item:Typical Specifications(refer to official documentation)
Number of Terminals:Supports 30-50 signal connections(specific specifications subject to actual model).
Compatible Voltage:Control side:24V DC;Load side:110V AC/220V AC,etc.
Maximum Load Current:Single relay output supports 1-5A(depending on load type).
Isolation Strength:Control-to-load isolation≥1500V AC(1 minute).
Mounting:Compatible with Mark V system racks or standard DIN rails.
Dimensions:Approximately 200mm×100mm×50mm(compact design).
