Description
IS200WROBH1AAA is a Power Distribution Board under the Mark VI series.GE created the board as part of their Speedtronic range.The Mark control platform offers scalable redundancy levels. A single (simple) controller with simplex I/O and a single network is the foundation of the system.The dual system has two controllers
singular or fanned TMR I/O, and dual networks, which increases reliability and allows for online repairs. Three controllers, singular or fanned TMR I/O, three networks, and state voting amongst controllers make up the TMR system, which allows for maximum fault detection and availability.
The core distribution system and branch circuit elements are two distinct types in the PDM.They are responsible for a cabinet's or a set of cabinets'primary power management.The branch circuit elements take the core output and distribute it to specific circuits in the cabinets for consumption.Branch circuits have their own feedback methods that are not included in the PPDA I/O pack's feedback. IS200WROBH1A is a Relay Fuse And Power Sensing card from WROB.The card has twelve fuses on it.The fuse has a 3.15 A rating and is rated for 500VAC/400VDC.

Features:
- Expands discrete relay output capability
- Relay fuse monitoring and power sensing functions
- Supports Simplex and TMR system configurations
- Twelve 3.15 A industrial protection fuses
The board contains twelve fuses, each rated at 3.15 A, 500 VAC / 400 VDC (Littelfuse 04773.15MXP), providing fused power distribution to external relay circuits. Fuse voltage feedback is available for 24 VDC, 48 VDC, 125 VDC, 120 VAC, and 240 VAC systems, with isolated voltage sensing that is not polarity sensitive. This allows the board to monitor the health of each fused branch and report status back to the control system.
The IS200WROBH1AAA GE Discrete Contact Output Option Board may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The board supports simplex, redundant, and TMR (Triple-Modular Redundant) configurations. In TMR mode, it mounts on the TDBT terminal board alongside contact input terminal boards (TBCI). In non-TMR configurations, it mounts on the TDBS board, converting it into a functional equivalent of the TRLY relay board. This flexibility allows the control system to scale from basic single-controller setups to fully redundant, fault-tolerant architectures with three controllers and state voting.
The IS200WROBH1AAA includes self-diagnostic capabilities that continuously monitor signal consistency, hardware integrity, and configuration validity. Faults such as inconsistent signals, blown fuses, or hardware failures are reported through the control system interface. The board also features overcurrent, overvoltage, short-circuit, and overtemperature protection to safeguard both the module and connected field devices.
- Gas/Steam Turbine Control: Interfaces control systems with actuators, valves, and auxiliaries in power plants
- Industrial Energy: Regulates control signals for combined-cycle and co-generation facilities
- Safety/Protection: Triggers trips and safety sequences upon detecting power anomalies
- Heavy-Duty Automation: Switches high-voltage/current field devices with ruggedized, conformal-coated architecture for harsh environments

Relay & Power Wiring: Connect field wiring to the corresponding terminals on the base terminal board. The IS200WROBH1AAA board features 12 standard fuses (default fuse rating is 3.15 A, 500 VAC/400VDC). Verify that all external field circuits are appropriately rated and terminated.
Communication & Feedback: Attach any required D-type computer cables or communication lines to the I/O pack to establish data backplane connection.
Redundancy: If your turbine system runs in Simplex or TMR (Triple Modular Redundant) mode, verify that the module is correctly configured in your setup.
Technical notes
The IS200WROBH1AAA functions as a relay control and power sensing interface. It receives low-level control signals from the Mark VI/VIe controller and switches electromechanical relay contacts to control field devices such as solenoid valves, contactors, motors, and alarm horns. The onboard relays handle resistive loads up to 5 A at 120/240 VAC; for inductive loads, the current rating is derated, and the use of external interposing relays is recommended to prevent contact degradation from arcing.
FAQs
-
What is the IS200WROBH1AAA ?
+The GE IS200WROBH1AAA is a protective option relay output board used in the GE Mark VIe Turbine Control System. -
What is the primary function of the IS200WROBH1AAA?
+It is a modified, conformal-coated option board that mounts with other Mark VIe boards (such as SRLY or TDBS) to provide enhanced capabilities to relay outputs, fused power distribution, and power sensing -
What are the specifications of the fuses on this board?
+The board features 12 fuses rated at 3.15 A. They are designed for 500 V AC or 400 V DC. -
What happens when it is paired with a TDBS board?
+When used with a TDBS board, it functions to detect the statuses of the fuses across the six fuse pairings on the board and turns the relay portion into an equivalent to the IS20TRLYH1B board
