Product Overview
The IS230TNRLH1B is a discrete output terminal base relay module designed for GE Mark VIe and Mark VIeS Speedtronic turbine control systems. It belongs to the IS230 series TMR (Triple Modular Redundant) I/O pack, serving as a critical hardware component for gas turbine and steam turbine control in power generation, oil & gas, and petrochemical industriesSaul Elect….
This module acts as the interface between the Mark VIe controller and field actuators, offering relay-based discrete output switching for valves, solenoids, alarms and safety shutdown circuits. With conformal coated PCB, it withstands vibration, temperature fluctuation and harsh cabinet environments in power plants. IS230TNRLH1B supports TMR redundant architecture to eliminate single points of failure, ensuring high availability for safety-critical turbine control applications.
