GE IS200ISBDG1A IS200ISBDG1AAA Insync Delay Board

The GE IS200ISBDG1A IS200ISBDG1AAA Insync Delay Board manages signal timing synchronization for turbine control systems. You will find this board essential for coordinating multiple protection relays. Its programmable delay feature ensures proper sequence ordering during startup and shutdown.

Dimensions, Weight, and Physical Layout

This Insync delay board measures 14.2 cm in length and 9.8 cm in width. Its height stays at 1.8 cm including all timing circuits. The total weight reaches 0.32 kilograms for compact rack mounting. A four-layer PCB provides excellent signal isolation between delay channels.

Delay Interfaces and Component Count

The GE IS200ISBDG1A IS200ISBDG1AAA Insync Delay Board offers eight independent programmable delay channels. Each channel accepts 24V DC input signals and produces delayed outputs. You also receive four bypass jumpers for zero-delay operation. In total, this board contains 112 individual electronic components. These include 8 timing ICs, 8 optocouplers, and 64 precision capacitors.

Energy Storage and Power Parameters

A 3.3V supercapacitor provides onboard energy storage for 72 hours. This backup retains programmed delay settings during power interruptions. The board draws only 3.2 watts from a nominal 24V DC supply. Peak inrush current stays safely below 1.5 amperes.

Delay Ranges and Environmental Limits

You get adjustable delay settings from 0.1 to 30 seconds per channel. The board achieves ±1% timing accuracy across the full range. A 50 MHz dedicated processor handles all timing coordination tasks. Therefore, the operating temperature ranges from -30°C to +70°C. Storage temperatures extend from -40°C to +85°C without performance loss.

Connectors, Configuration, and Additional Features

Two 20-pin ribbon cable headers connect to protection relay boards. A single 6-pin DIP switch block allows manual delay configuration. For similar static trip system timing applications, see the RMS-TSG-TZ-C model from the same manufacturer. However, this Insync delay board specializes in programmable signal synchronization exclusively. Mean time between failures (MTBF) exceeds 200,000 hours in continuous operation.
