FAQ
FAQ
Q1: What is the primary function of this terminal board?
A1: It distributes and switches trip commands from the control processor to field-level trip circuits through safety relays.
Q2: What does de-energize-to-trip mean in practice?
A2: Loss of control power or internal failure will cause the relays to release automatically, forcing the turbine into a safe shutdown state.
Q3: Can the trip contacts be wired in series for higher safety integrity?
A3: Yes, contacts can be configured in series or in voting logic at the system level to achieve higher protection reliability.
Q4: Is surge protection built into the relay outputs?
A4: The board includes suppression circuits to reduce voltage spikes caused by inductive loads such as solenoids and contactors.
Q5: How does the control system detect relay health?
A5: Relay states are monitored via feedback channels in the controller, enabling detection of failed or stuck contacts.
Q6: Is the board suitable for safety-critical applications?
A6: It is engineered specifically for turbine protection systems where deterministic response and fail-safe behavior are required.
Q7: Can the relays be driven independently?
A7: Each relay is individually controlled, allowing selective tripping based on logic conditions or protection thresholds.
Q8: Does the board require manual configuration or jumpers?
A8: No local configuration is required; all operational logic is defined in the control system software.
