GE IS200DAMDG2A IS200DAMDG2AAA G/D Interface Board – Mark VI Series

Technical Specifications

The GE IS200DAMDG2A (also IS200DAMDG2AAA) converts generator digital signals to drive outputs. This board measures 25.4 cm in length and 20.3 cm in width. It weighs approximately 0.9 kg. The unit contains eight digital input channels and six digital output channels. A single 64-pin backplane connector provides system interface. Additionally, the board features one 37-pin D-sub connector for field wiring. The GE IS200DAMDG2A IS200DAMDG2AAA stores 256 KB of configuration data in flash memory. It also holds 64 KB of buffer memory for signal latching. This module uses no battery for energy storage.

Design and Integration

This GE IS200DAMDG2A IS200DAMDG2AAA interfaces generator protection relays with the Mark VI controller. The eight digital inputs monitor trip status and breaker positions. Then, the six digital outputs send command signals to generator control devices. Therefore, the board enables seamless communication between protection and control systems. The 37-pin D-sub connector simplifies field cabling. Meanwhile, the buffer memory latches fast transient signals reliably. For a similar protection component, see the RMS-TSG-TZ-C on Alibaba. However, that static trip relay focuses on overcurrent protection rather than general interfacing.

Reliability and Operation

The GE IS200DAMDG2A IS200DAMDG2AAA operates from -30°C to +65°C. Its flash memory retains configuration without any external battery. Consequently, you avoid periodic maintenance for memory backup. The board meets GE’s response time specification of 2 milliseconds. Each unit undergoes 48-hour continuous I/O cycling before shipping.
