Description / Overview
The GE DS200DTBAG1A is a Digital Contact Terminal Board (DTBA) designed for the Mark V Speedtronic turbine control system. It serves as a critical interface for digital input and output signals, connecting switches, relays, and sensors to the control system.
This board features 190 pluggable contact points arranged in two 95-point terminal blocks, enabling dense signal integration while saving significant cabinet space. Moreover, it supports hot-swappable terminals, allowing maintenance without interrupting power.
The DS200DTBAG1A includes 2 A relay contacts capable of directly driving fuel valves, field breakers, and high-power contactors. Therefore, it eliminates the need for intermediate relays, reducing system costs by up to 20%. Additionally, it supports TMR (Triple Modular Redundancy) fault tolerance and meets API 670 SIL2 standards for rotating machinery protection.
