The IS220PTURH1B is a turbine-specific primary I/O trip pack module designed for use within the Mark VIe (and Mark VI) turbine control system family.
It handles primary trip logic, discrete I/O, speed and protection inputs/outputs, and is built for turbine applications requiring high reliability, fast response, and redundant network connectivity.
This module interfaces to turbine terminal boards, breaker coils, overspeed detectors, and emergency shutdown circuits, acting as a dedicated protection and I/O interface in power generation, gas/steam turbines, and process-industrial setups.
It supports simplex and triple modular redundant (TMR) configuration, dual Ethernet ports for communication, extensive diagnostics, and rugged design for harsh industrial environments.

| Application Focus | Turbine trip logic, breaker coil control, primary I/O protection |
The IS220PTURH1B finds use in many critical industrial and power-generation environments:
Gas turbine emergency shutdown systems: implementing overspeed protection, flame failure detection, trip coil actuation.
Steam turbine control: handling primary I/O for turbine protection boards, synchroniser logic, trip circuits.
Power generation plants: acting as a dedicated primary I/O trip module, ensuring fast, reliable response for turbine and generator protection.
Oil & gas platforms and offshore facilities: where rugged, redundant protection modules are required to interface with turbine systems under harsh conditions.
Retrofit and modernization projects: replacing older trip-pack modules while maintaining compatibility with Mark VI/Mark VIe control architectures.
Selecting the IS220PTURH1B brings several key advantages:
Dedicated turbine protection functionality: specifically designed for primary trip logic rather than general I/O, yielding faster response and fewer compromises.
Redundancy capable: supports both simplex and triple modular redundant architectures, giving high system availability and fault tolerance.
Dual Ethernet communication: provides network redundancy, reducing risk of communication failure.
Rugged environmental performance: many variants rated for wide temperature ranges, vibration/EMI resistance, and heavy-duty industrial use.
Heavy-duty physical specification: at ~3.0 kg and sizeable form factor, indicating robust internal design with ample electronics for the protection role.
Ease of integration: compatible with turbine control terminal boards, control systems in the Mark VI/Mark VIe family, simplifying engineering and replacement.
Strong diagnostics: built-in self-test, indicator LEDs, and fault-logging ease commissioning and maintenance.
