Features:
- Provides twelve relay-output positions for Mark VI discrete-output functions.
- Brings normally open and normally closed relay contacts to field terminals.
- Interfaces VCCC or VCRC output control with customer-powered contactors, solenoids, and other loads.
IS200TRLYH1B separates the electronic output command from the external load circuit by using relay contacts as the switching boundary.
Each of the twelve positions can serve the field function assigned in the cabinet output schedule, including applications organized as voted or nonredundant outputs.
Because the connected equipment supplies its own load power, the terminal board carries relay contact switching rather than distributing controller logic power to the device.
Quotation and availability support for General Electric IS200TRLYH1B Relay Output Terminal Board is available through Apter Power.

Matching an IS200TRLYH1B output circuit before transfer
- I/O source: Confirm whether the board is driven from VCCC or VCRC and preserve the associated cable position.
- Contact use: Record the exact normally open or normally closed terminals used for each customer circuit.
- Field power: Identify supply voltage, polarity, branch protection, and the point where customer power enters the output path.
- Load identity: Tie every relay position to its actual contactor, solenoid, or auxiliary function before moving conductors.
Following an IS200TRLYH1B command to the field device
- Controller state: Confirm that the intended logic command reaches the associated I/O channel.
- Relay response: Observe coil pickup or the available relay indication rather than inferring operation from software status.
- Contact voltage: Measure on both sides of the selected contact to expose a failed contact or missing field feed.
- Load result: Check terminal voltage and current at the field device so an open cable or failed coil is not assigned to the board.
What different IS200TRLYH1B failures usually isolate
- One output inactive: Compare its command, relay pickup, contact, fuse, wiring, and load with a known working circuit.
- All outputs drop together: Investigate the common I/O cable and customer supply before replacing twelve independent relay paths.
- Protective device opens: Measure load current and coil condition; repeated operation can indicate a field short rather than a board fault.
- Voted channels disagree: Compare each participating command and field contact separately before isolating the shared load circuit.
How IS200TRLYH1B is allocated in Mark VI cabinets
- Process actuation: Individual relays can switch customer-powered contactors or solenoids according to the project output schedule.
- Protection outputs: Selected circuits may participate in voted actions where every contributing path must be proven independently.
- Auxiliary duties: Nonredundant alarms or permissive contacts can coexist with higher-reliability outputs on the same board.
- Engineering limit: The board name and output count do not determine application; only the approved drawings establish each channel's function and safe state.
