I/O modules

The DS200TCTEG1A DS200TCTEG1ABA operates as a dedicated trip board for the Mark V series. This unit monitors emergency stop signals from multiple turbine sensors. It initiates an immediate turbine shutdown when a fault condition occurs. Consequently, this board provides essential over-speed and over-temperature protection.

Technical Specifications

We engineered this TC2000 trip board for fail-safe emergency protection applications. Its single-slot form factor fits directly into a standard Mark V rack. Moreover, the board features multiple comparator circuits for signal evaluation.

Trip Logic and Signal Processing

The DS200TCTEG1A DS200TCTEG1ABA accepts speed signals from magnetic pickups directly. It also receives temperature inputs from multiple thermocouple channels simultaneously. The onboard comparator logic evaluates these signals against user-defined safety setpoints. When any value exceeds its threshold, the board activates the corresponding trip relay immediately.

Output Configuration and Status Indication

This TC2000 board drives three independent relay outputs for external protection circuits. Each relay provides a dry contact for series connection into safety loops. Eight front-panel LEDs show you the real-time status of each trip channel. As a result, you can verify proper board operation during routine maintenance inspections.

Energy State During Power Interruption

The DS200TCTEG1A DS200TCTEG1ABA does not rely on battery-backed memory for trip logic. Instead, it uses latching relays that retain their last state during power loss. This design ensures failsafe operation without requiring any energy storage components onboard.

Installation Guidance

Mount this trip board into any standard Mark V rack using the card guides. Always connect the 40-pin ribbon cable to the termination board first. Verify all trip setpoints carefully before placing the turbine back into service.
