GE IS200WROBH1A IS200WROBH1ABA Power Induction Board
GE IS200WROBH1A IS200WROBH1ABA
1. Product Overview
IS200WROBH1A and IS200WROBH1ABA are WROB Relay Fuse and Power Sensing Boards manufactured by General Electric (GE), belonging to the GE Mark VIe/Mark VI series. Designed for PDIO (Discrete Input/Output) module systems, the boards serve as WROB option cards and can be matched with various terminal boards for system operation.
Specifically, IS200WROBH1ABA is an upgraded version of IS200WROBH1A. It has undergone two functional revisions and one circuit layout revision, categorized as the SRLY Option Board-B.

3. Product Features
- Flexible Redundancy Modes: Supports three operating modes, including Simplex, Redundant, and Triple Modular Redundancy (TMR), adapting to diverse industrial control redundancy requirements.
- Strong Compatibility: Compatible with a wide range of terminal boards such as TDBS, SRLY, and TDBT, enabling flexible system configuration and assembly.
- Extended Functions in TMR Mode: When installed on the TDBT board for TMR applications, it can realize equivalent functions of Terminal Board and Terminal Board Contact Input (TBCI).
- Independent Relay Function: In simplex mode, it can create TRLY relays to provide sensing and fused power distribution for the first six relay outputs, ensuring stable power output.
- High Operational Reliability: Part of the GE Speedtronic series, it features mature industrial design, stable performance, and strong durability against complex operating environments.
- Static Sensitive Design: As an electrostatic-sensitive circuit board, it requires standardized ESD (Electrostatic Discharge) protection measures during operation, storage and installation.
4. Structure and Composition
- PCB Structure: Adopts a standard printed circuit board (PCB) structure, equipped with two large female interfaces on the board for stable signal and power connection.
- Internal Electronic Components: Integrated with multiple precision resistors, transistors, capacitors and other core electronic components to ensure accurate circuit operation.
- Fuse Module Configuration: Comes with 12 independent fuses (FU1-FU12). The built-in fuse module increases the overall thickness of the board by approximately four times for overcurrent protection.
- Protective Coating: Partial product versions are coated with conformal coating to enhance corrosion resistance, moisture resistance and environmental adaptability.
- Insulation Design: Designed with three factory-insulated drilled holes to achieve effective electrical isolation and prevent short-circuit and interference risks.
