IS230TNTCH3C is a Thermocouple Input Assembly Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. A relay output terminal module is a device used in industrial control systems to provide an interface between a control system and external devices, such as motors, solenoids, valves, or other electrical equipment. It typically consists of multiple relay outputs, which are electrically isolated switches that can be controlled by the control system to turn devices on or off. It seamlessly integrates into the larger control infrastructure, contributing to the overall functionality and performance of the system. Its purpose is to provide relay-based output control, allowing for the activation or deactivation of various external devices or equipment. The module is built with robustness and durability in mind, ensuring consistent and reliable operation even in challenging industrial environments. It is engineered to withstand demanding conditions, including extreme temperatures, vibrations, and electrical disturbances, guaranteeing long-term stability and performance. This relay output terminal module offers multiple relay outputs, enabling the control of various devices simultaneously. The exact number of relay outputs may vary depending on the specific model and configuration.


  • Relay Outputs: The module contains multiple relay outputs, each capable of switching electrical loads. The number of relay outputs can vary depending on the specific module.
  • Electrical Isolation: Each relay output is electrically isolated from the control system and other relay outputs. This isolation ensures that the control system remains protected from voltage spikes, noise, and faults that may occur in the external devices.
  • Control Signal Compatibility: Relay output modules are designed to be compatible with the control signals provided by the control system. These signals can be digital or analog, and the module converts them into suitable output signals for the relays.
  • Switching Capacity: The relay outputs have specific switching capacities, including the maximum voltage and current they can handle. These specifications determine the types of devices that can be controlled using the module.
  • Mounting Options: Relay output terminal modules can be designed for various mounting options, such as DIN rail mounting or panel mounting, depending on the application and the control system setup.

What is the purpose of a relay output terminal module?

A relay output terminal module serves as an interface between a control system and external devices. It allows the control system to control the switching of electrical loads such as motors, solenoids, valves, or other equipment by using relay outputs.

How does a relay output terminal module work?

The control system sends control signals to the relay output terminal module, which in turn activates or deactivates the relay outputs accordingly. Each relay output acts as a switch that can turn devices on or off based on the control signals received.

How are relay output terminal modules installed?

Relay output terminal modules are typically designed for easy installation. They may have DIN rail mounting clips for easy attachment to DIN rails commonly used in industrial control panels. Some modules also offer panel mounting options for direct attachment to panels or enclosures.
