GE, a global technology leader, recently introduced a new turbine dedicated I/O module, the IS220PHRAH1A, designed to improve the reliability of turbine operations and reduce long-term maintenance costs. The IS220PHRAH1A can be directly interfaced with specific turbine site equipment, reducing the use of instruments needed to connect, thereby increasing operational reliability and reducing long-term maintenance costs.

The I/O module is commonly used in conjunction with TREAH_A terminals and is widely used in emergency shutdown applications for air-derived turbines. The IS220PHRAH1A module can be connected to a barrier or box terminal block and has restrictions on field wiring for voltage sensing, limiting the cable length to 1000 feet of 18 AWG wire. It is worth noting that the IS220PHRAH1A cannot be automatically reconfigured when swapping BPPB P-Pack with BPPC P-Pack.

The front panel of the IS220PHRAH1A module has the component ID number and multiple LED indicators, which are arranged in pairs and labeled PWR/ATTN, LINK/TxRx and ENET 1, and LINK/TxRx and ENET2. There is also a component labeled IR Port at the bottom of the panel. The module accepts three speed signals, including deceleration, acceleration and overspeed, and has a hardware-implemented overspeed function. The module monitors the status and operation of the selected trip plate through a series of integrated feedback signals, supporting TMR and single backup protection.

In addition, the IS220PHRAH1A has a high-speed processor built in and two fully independent 10/100 Ethernet ports, features a hardware reset circuit and a watchdog timer, and monitors temperature via internal sensors. The introduction of this module further enriches ABB’s product line in industrial automation and control, providing customers with an efficient, reliable and user-friendly interface solution.
