Functional Description
IS200TRLYH1CCB is a Relay Output Board developed by GE. It is a part of Mark VIe control system. The terminal board is designed to manage relay output with contact sensing, accommodating up to 12 plug-in magnetic relays. Specifically, the first six relay circuits on this board are configured as Form-C contact outputs, which are utilized to drive external solenoids. For powering these solenoids, the board supports a standard 125 V DC or 115 V AC source. This power source is equipped with fuses and on-board suppression to ensure safe and reliable operation in field applications.
Features
- The terminal board comprises 12 plug-in magnetic relays, with the first six circuits featuring Form-C contact outputs designed to drive external solenoids effectively. A standard power source of either 125 V dc or 115 V ac, complete with fuses and on-board suppression, is provided for field solenoid power, ensuring reliable and safe operation.
- For simplex operation, control signals and monitor feedback voltages are transmitted between the I/O board and module through the JA1 cable, facilitating seamless communication and control integration. Relay drivers, fuses, and jumpers are conveniently mounted on the relay board, optimizing space utilization and enhancing accessibility for maintenance and troubleshooting tasks.
- Relays 1-6 are equipped with a 250 V Metal Oxide Varistor (MOV) for transient suppression between normally open and power return terminals, safeguarding against voltage spikes and ensuring reliable operation in challenging environments. The relays are driven at the frame rate and boast a robust 3.0 A rating. They feature a rated contact-to-contact voltage of 500 V ac for one minute and a rated coil-to-contact voltage of 1,500 V ac for one minute, ensuring high voltage tolerance and safety. The typical time to operate is 10 ms, ensuring swift response and efficient performance.
- The relay outputs are equipped with failsafe features to mitigate potential risks. In the event of a cable being unplugged or communication loss with the associated I/O board, the inputs vote to de-energize the corresponding relays. This proactive approach enhances safety and prevents unintended operation or hazards.
- With a typical maximum response time of 25 ms, the terminal board swiftly reacts to input signals, facilitating rapid relay activation and enhancing system responsiveness. Similarly, the terminal board exhibits a typical maximum response time of 25 ms when transitioning to the off state. This ensures prompt relay deactivation, contributing to efficient control and operation.
Fault detection
- Loss of Relay Excitation Current: Relay excitation current is critical for the operation of electromagnetic relays. When this current is lost, the relay cannot switch states as intended. This can be caused by issues such as power supply failures, faulty wiring or connections, or defective relay coils. Detecting a loss of relay excitation current involves monitoring the current flow to the relay coil. If the current falls below a predetermined threshold, it triggers an alarm or a fault indication. This ensures that any issues are quickly identified and addressed to prevent system malfunctions.
- NO Contact Voltage Disagreement with Command: The NO (Normally Open) contact of a relay should reflect the state commanded by the control system. A fault condition is indicated when there is a disagreement between the expected command and the actual voltage state of the NO contact. For instance, if the command is to close the contact (energize the relay) but the NO contact remains open (no voltage present), it indicates a fault. Possible causes for this discrepancy include mechanical failure of the relay, electrical issues such as short circuits or open circuits, Faulty control signals. To detect this type of fault, the system continuously compares the command signal with the actual state of the NO contact. Any mismatch triggers a fault alert, prompting further investigation and corrective action.
- Unplugged Cable or Loss of Communication with I/O Board: Relays often rely on communication with an I/O (Input/Output) board for control and monitoring. If the communication is lost due to an unplugged cable or a failure in the communication system, the relays will de-energize as a fail-safe mechanism. This prevents unintentional operations and ensures safety. Key causes of such communication loss include disconnected or damaged cables, faulty connectors, and malfunctioning I/O boards. To detect this condition, the system continuously monitors the communication link between the relays and the I/O board. If communication is interrupted, an immediate fault alert is generated, and the relays are de-energized to prevent unintended actions. This ensures that any issues with communication are promptly addressed, maintaining the integrity and safety of the relay system.
Contact Feedback Threshold
DC Voltage Range:
- Nominal Voltage: 125 V dc
- Threshold Range: 70-145 V dc
- Threshold Voltage: 45 to 65 V dc
AC Voltage Range (115 V rms):
- Nominal Voltage: 115 V rms
- Threshold Range: 90-132 V rms

Frequently Asked Questions
What is IS200TRLYH1CCB?
It is a Relay Output Board developed by GE under the Mark VIe series.
What are the jumpers JP1 through JP12 used for?
Jumpers JP1 through JP12 are utilized for contact voltage sensing. If contact voltage sensing is required for specific relays, jumpers should be inserted accordingly to enable this functionality.
What is the purpose of fuses FU1 through FU12?
Fuses FU1 through FU12 serve the purpose of providing power to the relays on the terminal board. If power is required for relays 1-6, two fuses should be placed in each power circuit supplying those relays. For instance, FU1 and FU7 supply power to relay output 1.
