IS200TRLYH1BGG is a coil sensing terminal board developed by GE. It is a part of Mark VIe control system. The Relay Output with coil sensing terminal board is a crucial component designed to facilitate relay-based control and signaling functions within the system. With its versatile configuration options and robust design features, the TRLY_1B terminal board offers reliable operation and flexibility in various applications.
- Plug-in Magnetic Relays: Accommodates 12 plug-in magnetic relays, providing ample capacity for diverse control and signaling requirements within the system.
- Configurable Relay Circuits: The first six relay circuits are configurable via jumpers to support either dry, Form-C contact outputs, or to drive external solenoids, offering flexibility in adapting to different operational needs.
- Solenoid Power Options: For field solenoid power, the board offers multiple power source options, including a standard 125 V DC or 115/230 V AC source, as well as an optional 24 V DC source. Individual jumper-selectable fuses and on-board suppression ensure safe and reliable operation of field solenoids.
- Isolated Form-C Contacts: Relays 7-11 feature unpowered isolated Form-C contacts, providing additional signaling capabilities while maintaining electrical isolation for enhanced safety and reliability.
- Special Application Relay: Output 12 is dedicated to a special application, such as ignition transformers, utilizing an isolated Form-C contact for precise control and signaling in unique scenarios.
- Number of Relay Channels: Boasts 12 relay channels, offering extensive capacity for relay-based control and signaling applications within the system.
- Relay Configuration
- 6 Relays with Optional Solenoid Driver Voltages: These relays are versatile, supporting optional solenoid driver voltages to accommodate diverse operational requirements.
- 5 Relays with Dry Contacts Only: These relays feature dry contacts only, suitable for applications where external solenoid drivers are not required.
- 1 Relay with 7 A Rating: This relay is specifically rated for higher current applications, offering robust performance under demanding conditions.
Caution and Safety Considerations
- Voltage Compatibility: In 240 V AC applications, it is crucial to avoid inadvertent cross-connections between the 240 V AC and DC voltages to prevent voltage surges that may exceed the Transorb rating, potentially leading to component failure.
- Transorb Protection: Most AC supplies operate with a grounded neutral. In the event of an inadvertent connection between the 125 V DC and AC voltage, the sum of the AC peak voltage and the 125 V DC may be applied to Transorbs connected between DC and ground. However, in 120 V AC applications, the Transorb rating can withstand the peak voltage without causing failure, providing an additional safety margin.
Maximum Load Current
- 0.6 A for 125 V DC operation
- 3.0 A for 24 V DC operation
- 3.0 A for 115/230 V AC, 50/60 Hz operation
- 6 A at 115 V AC for Relay 12 only
Relay Contact Rating
- 24 V DC Voltage Current Rating: 10 A for resistive current, 2 A for inductive current (L/R = 7 ms) without suppression.
- 125 V DC Voltage Current Rating: 0.5 A for resistive current, 0.2 A for inductive current (L/R = 7 ms) without suppression.
- 125 V DC Voltage Current Rating: 0.5 A for resistive current, 0.65 A for inductive current (L/R = 150 ms) with suppression (MOV) across the load.
- Loss of Relay Solenoid Excitation Current: The system incorporates fault detection mechanisms to identify instances of loss of relay solenoid excitation current. This detection system ensures prompt identification of any interruptions in the solenoid excitation circuit, enabling timely troubleshooting and remedial action to restore normal operation.
- Coil Current Disagreement with Command: Additionally, the system continuously monitors coil current to detect any discrepancies between the commanded current and the actual current flowing through the relay coil. This proactive approach enables the system to promptly identify and respond to deviations from expected behavior, minimizing the risk of potential malfunctions or system failures.
- Unplugged Cable or Loss of Communication with I/O Board: In the event of an unplugged cable or loss of communication with the I/O board, the system is designed to deactivate relays associated with the affected communication channel. This automatic de-energization of relays ensures that the system maintains operational integrity even in the face of communication disruptions, preventing potentially hazardous or undesirable outcomes.
- Proactive Monitoring: By implementing proactive fault detection mechanisms, the system enhances its ability to maintain operational reliability and mitigate the risk of unexpected downtime or malfunctions. Continuous monitoring of critical parameters enables the system to identify and address potential issues in real-time, minimizing the impact on system performance and ensuring uninterrupted operation.
- Prompt Response to Anomalies: Upon detection of any fault condition, the system initiates appropriate response measures to rectify the issue and restore normal operation. Whether it involves activating backup systems, issuing alerts for manual intervention, or executing automated recovery procedures, the system's responsiveness plays a vital role in safeguarding overall system reliability and functionality.

Frequently Asked Questions
What is IS200TRLYH1BGG?
It is a coil sensing terminal board developed by GE under the Mark VIe series.
How is the status of each relay monitored?
The output of each relay, specifically the coil current, undergoes continuous monitoring and is compared against the commanded value at the frame rate. If there is a lack of agreement for four consecutive frames, an alarm is generated, indicating a potential issue with the relay operation.
How is the solenoid excitation voltage monitored?
The solenoid excitation voltage is monitored downstream of the fuses, and an alarm is latched if it falls below the threshold of 12 V DC. This ensures that adequate voltage is supplied to the solenoids, essential for their proper operation.
What happens if any relay output becomes nonoperational?
In this event, a composite diagnostics alarm, designated as L3DIAG_xxxx, is triggered. This alarm serves as a comprehensive indication of potential issues within the relay system, prompting further investigation and corrective action.
How are hardware compatibility issues detected?
When an identification (ID) chip is read by the I/O processor, any mismatch encountered with the expected hardware configuration results in the creation of a hardware incompatibility fault. This fault signals a discrepancy between the detected hardware and the expected configuration, alerting users to potential compatibility issues that require resolution.
