        Features:

        • 16-bit resolution with 100 Hz sampling per channel, delivering ±0.25% FS accuracy for precise gas/steam turbine exhaust monitoring .
        • Auto-sensor recognition, built-in cold junction compensation, and 2 ms open/short circuit detection for rapid fault diagnosis .
        • Dual Ethernet ports supporting TMR/duplex configurations and hot-swap design (<5 min MTTR) for non-stop system availability .
        The IS220PTCCH1B is engineered to meet the demanding response requirements of gas turbine exhaust temperature monitoring. It features a 16-bit A/D converter and a dedicated sampling rate of 100 Hz per channel, enabling the control system to detect rapid thermal changes such as flame instability or combustor blowout within a 10 ms window .

        Equipped with advanced onboard intelligence, the IS220PTCCH1B continuously monitors itself and its field wiring. It includes auto-sensor recognition that identifies the type of thermocouple connected (E, J, K, etc.) and its polarity without manual configuration, preventing human configuration errors . Crucially, it performs hardware line monitoring capable of detecting an open circuit (broken wire) or short circuit in the thermocouple loop within 2 milliseconds and immediately flags the data as invalid .

        The IS220PTCCH1B is built for the redundancy requirements of critical power generation assets. It features dual independent 10/100 Mbps Ethernet ports that support Modbus TCP/IP and Profibus DP protocols, allowing integration into redundant I/O networks (IOnet) . This hardware supports Simplex, Duplex, and full Triple Modular Redundant (TMR) control architectures without additional external switches, allowing a single combustion temperature sensor to feed three independent processor channels simultaneously for 2oo3 voting logic .

        The IS220PTCCH1B GE Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

It supports Simplex (single channel), Duplex (dual backup networks), and Triple Modular Redundancy (TMR) architectures. In TMR setups, three individual PTCC packs plug into a single TBTCH terminal board to achieve bumpless voting hardware protection.
        • Dual IONet Communications: Features dual, full-duplex 100 Mbps Ethernet ports (IONet). This proprietary, deterministic network enables the pack to interoperate in real-time with Mark VIe master controllers.
        • Sensor Flexibility: Natively interoperates with diverse industry-standard sensor types, including E, J, K, S, and T-type thermocouples (whether grounded or ungrounded) as well as raw millivolt signals ranging from -8 mV to +45 mV.
        Description
        The IS220PTCCH1B is a Thermocouple Input Module from General Electric, specifically designed for the Mark VIe Speedtronic platform to manage critical turbine temperature monitoring. This IS220PTCCH1B features 12 combustion-optimized inputs with a dedicated cold junction, supporting conventional thermocouples such as Types E, J, K, S, and T for precise exhaust temperature measurement.

        To ensure high accuracy, the IS220PTCCH1B utilizes 16-bit A/D conversion with 100 Hz sampling per channel and ±0.25% FS accuracy. The IS220PTCCH1B is equipped with dual redundant Ethernet ports (Modbus TCP/IP, Profibus DP), allowing parallel connection to DCS and cloud platforms for real-time diagnostics and firmware updates. It also supports hot-swap replacement for easy maintenance.

        For reliability, the IS220PTCCH1B integrates comprehensive self-diagnostics, including flash memory, RAM, and power supply monitoring. Its isolation rating of 1500 Vrms prevents ground loops, and its ATEX Zone 2 certification makes the IS220PTCCH1B suitable for hazardous environments. It operates on 28 Vdc with a current draw of 0.16 A.
