I/O modules

The DS200TCTSG3A DS200TCTSG3ACC functions as a critical safety board for the Mark V series. This unit monitors turbine overspeed and over-temperature conditions in real time. It triggers an immediate shutdown when it detects any dangerous parameter. Therefore, this board protects your equipment from catastrophic mechanical failures.

Technical Specifications

We designed this simplex trip board for high-reliability emergency shutdown applications. Its compact form factor fits directly into a standard Mark V rack slot. Additionally, the board includes multiple relay outputs for trip signal distribution.

Trip Logic and Input Processing

The DS200TCTSG3A DS200TCTSG3ACC accepts speed signals from magnetic pickups directly. It also receives temperature inputs from multiple thermocouple channels. The onboard comparator logic evaluates these signals against user-defined setpoints. When a value exceeds the threshold, the board activates the corresponding trip relay.

Output Configuration and Status Indication

This simplex 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. Consequently, you can verify proper board operation during routine maintenance checks.

Energy State During Power Loss

The DS200TCTSG3A DS200TCTSG3ACC does not rely on battery-backed memory for trip logic. Instead, it uses latching relays that retain their last state during power interruptions. This design ensures failsafe operation without requiring energy storage components.

Installation Notes

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 before placing the turbine back into service.
