Features:
- Four speed paths accept either passive pickups or active sensors.
- K1 and K2 use forcibly guided contacts for primary trip outputs.
- One PTUR pack mounts directly on the simplex terminal assembly.
IS230STURH2A assigns different terminal pairs to passive magnetic pickups and active pulse sources.
Trip-contact position and solenoid-voltage returns allow the PTUR pack to supervise both relay paths.
The IS200STURH1A group is bounded to mechanical-drive operation because synchronizing circuits are omitted.
The General Electric IS230STURH2A Mark VIe Primary Turbine Protection Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Sensor Connections
- Passive inputs: Pickups land between PR#_H and PR#_L.
- Active inputs: Pulse sources use TTL# and PR#_L.
- Circuit count: Four independent speed paths are available.
- Frequency span: Measurement covers 2 Hz to 20 kHz.
Primary Trip Outputs
- Relay pair: K1 and K2 form the two trip outputs.
- Contact design: Both safety relays use forcibly guided contacts.
- Output count: The H1 group provides two primary trip paths.
- Parallel terminals: Selected points support redundant contact wiring.
Protection Supervision
- Contact return: Relay position is fed back to PTUR.
- Voltage return: Solenoid voltage is monitored for both channels.
- Speed testing: Input tests require an external test signal.
- Compatibility: Terminal ID mismatch produces a hardware fault.
Documented Use
- Drive type: H1 hardware supports mechanical-drive turbines.
- Protection task: The module handles primary overspeed inputs and trips.
- Pulse use: Four pulse-input circuits can serve non-synchronizing arrangements.
- Functional boundary: H1 provides neither primary synchronization nor emergency stop.
