Product info

Brand:

GE

Product Number:

IS200TREAH1A

Describe:

The GE IS200TREAH1A is a specialized turbine emergency trip terminal board designed as a core component of the GE Mark VIe control system . It serves as a critical interface between field devices (such as speed sensors and trip relays) and the turbine protection I/O packs (e.g., PPRO or YPRO), playing an essential role in ensuring the safe operation of gas and steam turbines .

-30℃ to +65℃

Storage Temperature:

-40℃ to 85℃

Humidity:

5% to 95% (non-condensing)

Input Channels (Speed):

6 passive pulse rate (MPU) inputs (supporting up to 3 shafts with 2 sensors each)

Speed Pulse Range:

2 Hz to 20 kHz

Output Channels (Trip):

3 TMR voted 24 V DC solid-state output contacts

Trip String Monitoring:

4 circuits, 24-125 V DC range

Application

Gas Turbines:

Used in Mark VIe control systems for aero-derivative and heavy-duty gas turbines. It monitors overspeed and processes emergency trip signals to prevent catastrophic rotor failure .

Steam Turbines:

Integrates with turbine protection systems to monitor critical parameters such as differential expansion, bearing vibration, and emergency overspeed, triggering a trip if safety limits are exceeded .

Compressor Trains:

Deployed in large centrifugal or reciprocating compressor applications to monitor shaft speed and vibration, providing a hardwired emergency shutdown (ESD) path for process protection .

FAQ

Q: What is GE's legacy in the industrial automation industry?

GE (General Electric), founded by Thomas Edison in 1889, was a global leader in PLC systems, including the famous Series 90-70, PACSystems RX3i/RXi, and VersaMax I/O platforms. While GE's industrial automation division was acquired by Emerson in 2019, these products remain widely used in factories worldwide .

Q: Does GE support hot-swapping of I/O modules?

Yes, most GE PACSystems and VersaMax I/O modules support hot insertion (hot-swapping) when used with compatible Network Interface Units. This allows module replacement without powering down the entire system. However, always verify your specific NIU configuration before performing

hot-swap .

Q: What is the most common failure mode in GE PLC modules?

Power supply aging (capacitor failure) and communication faults (Ethernet/Profibus dropouts).

Q: What is GE's proprietary communication protocol for PLCs?

GE developed SRTP (Service Request Transport Protocol) for Ethernet communication with PLCs, succeeding the serial SNP/SNPX protocols. It uses default port 18245 .
