The IS230SNHRH2A is a HART-enabled analog I/O pack for the GE Mark VIe and GE Mark VIeS platforms. It provides 4 analog input channels and 4 analog output channels, supporting 4–20 mA process signals with embedded HART digital communication for intelligent field device diagnostics and asset management.
The H2A revision is optimized for high reliability, precision control, and simplex architectures. It features 16-bit A/D and D/A conversion, galvanic isolation, and direct terminal board mounting to improve vibration resistance in turbine and heavy industrial environments.

Gas and steam turbine control
Smart valve position control
Pressure and temperature transmitter integration
Predictive maintenance and remote calibration systems
Commonly used in power generation and heavy process automation where smart instrument communication is required.
Q1: Can it be used in TMR systems?
This H2A version is optimized for simplex architectures. TMR applications require system-level design verification of terminal boards and voting logic.
Q2: Does it support HART pass-through?
Yes. HART digital data can be transmitted through IONet to asset management software for remote device configuration without interrupting the 4–20 mA control signal.
