GE IS2020DRLYH1AA MKVI, Relay Terminal Board, (DIN Mount)

 

The IS2020DRLYH1AA is a crucial component for converting digital commands into physical actions. Its main functions include:

  • Relay Outputs: The board contains a set of electromechanical or solid-state relays. When a digital command is sent from the main controller, the corresponding relay on the board is energized or de-energized, switching power on or off to a field device. This is used to control equipment like motor starters, solenoids, and alarms.
  • Isolation: The relays provide electrical isolation between the sensitive control electronics and the higher-power field devices. This protects the control system from voltage spikes, electrical noise, and faults in the field.
  • LED Indicators: The board typically has LED indicators that show the status of each relay. This provides a quick visual confirmation of whether a relay is energized, which is helpful for troubleshooting and maintenance.
  • DIN-Rail Mounting: The “D” in the DRLY part number indicates that the board is designed to be mounted on a DIN rail. This is a standard mounting method in industrial control cabinets, allowing for easy and organized installation.
  • Application: This board is used in the Simplex (non-redundant) and TMR (Triple Modular Redundancy) systems. In a TMR system, three separate DRLY boards receive commands from three redundant controllers, and a voting mechanism (typically in the field) selects the correct output to ensure reliable and safe operation.

الوصف

The GE IS2020DRLYH1AA is a Relay Terminal Board for the Mark VI series of GE’s Speedtronic Gas Turbine Control Systems. The “DRLY” in the part number signifies that it’s a Din-rail mountable Relay board. This board serves as the interface between the control system’s digital outputs and the external field devices that are controlled by relays.
