Product Introduction
IS220PTURH1B is a Primary Trip Protection Pack module designed specifically for steam turbines in GE's Mark VIe series control systems. It has an overspeed protection function. When the turbine speed exceeds the set value, it sends a signal to trigger an emergency shutdown. It can perform zero-speed detection to determine whether the turbine has stopped rotating. It can also monitor the vibration of the turbine and the temperature of key components to prevent equipment damage due to excessive vibration or overheating.

Product Details
The Primary Trip Protection (IS220PTURH1B) pack provides the electrical interface between one or two I/O Ethernet networks and a turbine control terminal board. The pack contains a processor board common to all Mark* VIe distributed I/O packs, a board specific to the turbine control function, and an analog acquisition daughterboard. The pack plugs into the TTURH1C terminal board and handles four speed sensor inputs, bus and generator voltage inputs, shaft voltage and current signals, eight flame sensors, and outputs to the main breaker. Input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. Output is through a DC-62 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.
As an alternative to TTURH1C, three IS220PTURH1B I/O packs can be plugged directly into a TRPAH1A terminal board. This arrangement handles four speed inputs per IS220PTURH1B, or alternately, fans the first four inputs into all three PTURs. Two solid-state primary trip relays are provided by TRPA. This arrangement does not support bus and generator voltage inputs, shaft voltage or current signals, flame sensors, or main breaker output.
To install the IS220PTURH1B I/O pack：
1. Securely mount the desired terminal board.
2. Directly plug the PTUR I/O pack into the terminal board connectors.
3. Mechanically secure the packs using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right-angle force applied to the DC-62 pin connector between the pack and the terminal board. The adjustment should only be required once in the life of the product.
4. Plug in one or two Ethernet cables, depending on the system configuration. The pack will operate over either port. If dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.
5. Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.
6. Use the ToolboxST* application to configure the I/O pack as necessary.
