Functional Description
IS200WROBH1ABA is a power distribution module developed by GE. It is a part of Mark VIe control system. The option board enhances the functionality of the TDBT by providing additional capabilities, particularly in TMR systems. When combined with the TDBT, it effectively replicates the relay circuit functionality of a terminal board.
Features
- Fused Sensed Power Distribution to the First Six Relay Contacts: The board facilitates fused sensed power distribution to the first six relay contacts. This ensures that each relay contact receives power with protection provided by fuses.
- Dedicated Power to the Last Relay Contact: Additionally, the board provides dedicated power to the last relay contact. This ensures reliable operation of the last relay contact without sharing power with other contacts.
- Electrical Circuit Configuration: Electrically, when the TDBT and WROBH1A are combined, they create a circuit that replicates the functionality of an terminal board. The default fuse values for the WROBH1A board are set to 3.15 A, providing appropriate protection for the circuit.
- Connector Configuration: Connector JW2 and its connections are essential for the proper functioning of the combined system but are omitted in this description to focus on the main circuit functionality.
Powered Output Circuits
Fused Output Circuits (Associated with Relays 1-6):
- Association with Relays 1-6: These fused output circuits are intimately associated with relays 1 to 6, aligning their operation seamlessly with the broader system requirements.
- Power Supply: Power is efficiently supplied to these circuits through parallel connectors JF1 and JF2, streamlining the process of power distribution within the system.
- Fused Protection: To bolster safety and reliability, both sides of the power source for each output circuit are fortified with fuses. This dual-fuse configuration provides robust protection against potential electrical faults, ensuring the integrity of the system under various operating conditions.
- Transient Voltage Spike Protection: Furthermore, each Normally Open (NO) relay contact within these circuits features integrated Metal Oxide Varistor (MOV) suppression. This crucial addition serves to mitigate the risks associated with transient voltage spikes, effectively safeguarding sensitive system components from potential damage during operation.
Unfused Output Circuit (Associated with Relay 12):
- Association with Relay 12: This particular output circuit is intricately linked with relay 12, serving a distinct purpose within the broader system architecture.
- Power Supply: Power for this circuit is supplied through connector JG1, ensuring a reliable and consistent power source for its operation.
- Transient Voltage Spike Protection: To bolster protection against transient voltage spikes, Metal Oxide Varistor (MOV) suppression is integrated across the Normally Open (NO) relay contact within this circuit. This crucial addition helps safeguard sensitive system components from potential damage caused by sudden voltage surges during operation.
