The PTUR module interfaces with dedicated turbine protection signals and supports the primary trip protection system.
It interfaces with turbine speed-related signals through the TRPA terminal board, supporting turbine speed monitoring and protection logic.
The module supports emergency stop input connections, allowing external shutdown signals to be incorporated into the turbine protection architecture.
It receives voltage detection signals from the terminal board for turbine protection and monitoring applications.
Dual Ethernet interfaces connect the I/O pack to the Mark VIe IONet network, enabling communication with the turbine control system.
