GE DS200HSTIG1A DS200HSTIG1AAA Speed Interface Board

Key Technical Specifications

This GE DS200HSTIG1A DS200HSTIG1AAA board operates from a 24V DC power supply. It accepts two independent speed sensor inputs up to 3 kHz each. The unit measures 19 cm in length, 13 cm in width, and 3.5 cm in height. Its total weight equals 0.48 kg without any packaging materials.

The GE DS200HSTIG1A DS200HSTIG1AAA includes two magnetic pickup conditioner circuits for gear tooth sensors. Additionally, it features one RS-485 port for digital speed reporting. A single 10-pin terminal block connects the sensor field wiring. The board contains 2 signal conditioners, 2 comparators, 1 microcontroller, 4 optocouplers, and 18 resistors.

GE DS200HSTIG1A DS200HSTIG1AAA stores energy using one electrolytic capacitor. This capacitor provides 47 µF at 35V rating for sensor bias filtering. Consequently, the board rejects electrical noise from industrial environments. Therefore, speed readings remain accurate even near variable frequency drives.

Design and Integration

Both the GE DS200HSTIG1A and GE DS200HSTIG1AAA versions share identical input conditioning. These boards use four-layer PCB construction with guarded analog traces for noise rejection. Consequently, the GE DS200HSTIG1A DS200HSTIG1AAA operates reliably from -15°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 60 mA typical current from the 24V DC supply. Each input channel includes overvoltage protection up to 100V peak. We recommend using shielded twisted-pair cables for all speed sensor connections.

Practical Application

This interface board connects magnetic speed sensors to a turbine or generator control system. It converts raw MPU signals into clean digital pulses for frequency measurement. The GE DS200HSTIG1A DS200HSTIG1AAA then transmits speed data via RS-485 to the main controller. Therefore, it enables precise overspeed protection and load sharing in power generation applications.
