PLCs, Power Supplies & Others

The GE DS200SSRAG1A DS200SSRAG1AAA switch high-power loads without moving mechanical contacts. These solid state relay boards serve the GE Mark V Turbine Control System. You can use either board to control heaters, motors, and solenoids. The units provide silent, fast switching with no contact wear.

Relay and Electrical Specifications

The GE DS200SSRAG1A DS200SSRAG1AAA switch AC loads up to 280 volts and 2 amps. These solid state relay boards use zero-crossing detection for clean switching. You can control each relay independently with 3 to 32 VDC signals. The units provide 4000 VAC isolation between control and power circuits.

Physical Dimensions and Weight

Each solid state relay board weighs 0.38 kg for secure chassis mounting. The unit measures 235 mm long by 152 mm wide. Its PCB thickness reaches 1.6 mm with four internal copper layers. You can mount either board using four M4 screws through the designated holes.

Interface and Connection Points

A 20-pin ribbon cable header handles control signals from the main controller. Two 10-pin terminal blocks provide AC load connections for all eight relays. The GE DS200SSRAG1A DS200SSRAG1AAA include a 4-pin power input connector. You will find eight red LED indicators showing each relay’s active status. Additionally, four test points provide access for control voltage measurements.

Energy Storage and Internal Circuitry

These solid state relay boards store minimal energy for snubbing purposes. Sixteen small capacitors provide 2.2 µF of total storage for transient suppression. The boards do not contain any battery for configuration retention. Each relay includes an internal snubber circuit for inductive load protection. A separate EEPROM stores no calibration data on these passive boards.

Component Layout and Construction

Eight individual solid state relay modules mount directly on the PCB. Each module contains a triac, optocoupler, and zero-crossing circuit. You will find 48 resistors, 32 capacitors, and 8 integrated relay modules on the board. The GE DS200SSRAG1A DS200SSRAG1AAA include MOV surge suppressors across each output. A clear plastic cover protects the relay modules from dust and debris.

Variant Equivalence and Use

The GE DS200SSRAG1AAA represents a functional equivalent or later revision. Both versions share identical dimensions, connectors, and mounting hole locations. You can substitute one for the other without hardware modifications. Transitioning to these boards restores solid state switching to Mark V systems. Use GE DS200SSRAG1A DS200SSRAG1AAA for heater control, valve actuation, or alarm annunciation. For best results, use external fuses to protect each relay output from short circuits.
