Core Features & Operating Capabilities
- Contact Output Expansion: Serves as a vital expansion termination node within the Mark V control architecture, multiplying and routing discrete output channels safely across control cores.
- Robust Signal Connectivity: Features dual heavy-duty terminal blocks accommodating a large quantity of signal and control wires (107 connections each).
- Inter-Board Compatibility: Interfaces seamlessly with core Mark V system components, linking directly with TCRA relay signal connectors and TCPD solenoid power feeds.
- Built-in Transient Protection: Populated with foundational protection elements—such as onboard diodes, rectifiers, and filtering capacitors—to stabilize switching voltages and suppress electrical noise in heavy industrial turbine environments.
