Product Precautions
- General Electric IS220PTURH1A forms part of a turbine primary-trip arrangement. Its speed, voltage and emergency-stop interfaces must match the specified terminal board and installed protection design.
Product type: Turbine-specific primary-trip module
Terminal-board pairing: IS200TRPAH1A
Specified supply: 28 V DC, 0.41 A DC for the paired arrangement
Terminal-board pairing: IS200TRPAH1A
Specified supply: 28 V DC, 0.41 A DC for the paired arrangement
The IS220PTURH1A identity belongs to the Mark VIe PTUR turbine-specific primary-trip function. Its specified accessory is IS200TRPAH1A. Treat the module, terminal board and installed turbine wiring as a coordinated arrangement; the terminal-board designation is a pairing requirement and does not mean that the board is included with the offered module.
The paired arrangement is rated for a 28 V DC power supply at 0.41 A DC. Its speed input is specified from −15 to +15 V DC, voltage input from 16 to 140 V DC and emergency-stop input from 18 to 140 V DC. These interface ranges serve different circuits and must not be interchanged when checking the installed terminations.
The emergency-stop power output is specified at 28 V DC open circuit and 17 mA DC short circuit; the contact output is rated at 28 V DC, 7 A DC. The open-circuit and short-circuit values describe boundary conditions, not a single normal operating point. Verify field loads, trip wiring and the approved functional test before returning the turbine protection arrangement to service.

The electrical values apply to IS220PTURH1A with the IS200TRPAH1A accessory terminal board. They are connection ratings for that arrangement, not proof of supplied terminal-board inclusion or an independent system safety rating. The planning guide is prepared by Apter Power; apply the complete manufacturer instructions and the stated applicability boundaries.
System and supply context: The electrical values apply to IS220PTURH1A with the IS200TRPAH1A accessory terminal board. They are connection ratings for that arrangement, not proof of supplied terminal-board inclusion or an independent system safety rating. Accessories are included only when itemized in the quotation.
Platform applications: The following applications describe GE Mark VIe functions. Match the complete IS220PTURH1A identity to the installed system before selecting a replacement.

-
Turbine primary trip
Integrate the PTUR module in the approved Mark VIe turbine trip arrangement. -
Speed-signal integration
Match the speed-signal circuit to the specified input range and terminal assignments. -
Emergency-stop circuits
Review input and power-output boundaries against the complete emergency-stop wiring. -
Protection maintenance
Retain the PTUR and TRPA pairing and validate trip behavior under the authorized test procedure.
Prepare IS220PTURH1A against the installed configuration and applicable General Electric instructions. Plan isolation and the resulting interruption of system operation before replacement.
Confirm the board pairing
Use the specified IS200TRPAH1A terminal-board arrangement.
Isolate trip circuits
Follow the site procedure before disturbing powered protection or emergency-stop wiring.
Distinguish input ranges
Do not interchange speed, voltage and emergency-stop input circuits.
Interpret boundary ratings
Keep open-circuit voltage separate from short-circuit current when reviewing the E-stop output.
Check the contact load
Review the 28 V DC, 7 A DC contact-output rating with the connected load and circuit protection.
Test the full function
Validate the complete turbine trip arrangement before release; a module replacement is not a system-level acceptance test.
