Functional Description

IS230TNRLH2E is a Relay Output DIN-Rail Module manufactured by General Electric. It is a part of the Mark VIe Control System. These relay outputs serve as a crucial interface between the control system and external devices or equipment.The module is specifically designed for DIN-rail mounting. This mounting option ensures easy integration and organized installation of the module within the overall control system. It acts as an interface between the control system and external devices, allowing the system to control and monitor various processes and equipment. The module's compatibility with the Mark VIe Control System ensures seamless integration and efficient operation.

Operation

• The relays utilized in the Relay Output DIN-Rail Module are designed to operate at the frame rate of the control system. They have a robust rating of 3.0 A, allowing them to handle high-current applications reliably. The rated contact-to-contact voltage for these relays is 500 V AC for one minute, ensuring safe and secure electrical connections within the controlled circuits.
• Furthermore, the rated coil to contact voltage is 1,500 V AC for one minute. This specification ensures sufficient insulation between the relay's coil and its contacts, preventing any potential voltage leakage or interference. The high coil to contact voltage rating contributes to the overall safety and reliability of the module and the control system.
• The relays in the module exhibit a typical operating time of 10 ms. This quick response time allows for efficient and prompt switching of electrical circuits based on the control signals received from the Mark VIe Control System. The fast operation ensures precise control and enables the system to respond rapidly to changes or events in the industrial processes.
• To provide protection against transients or voltage spikes, relays 1-6 in the module are equipped with a 250 V metal oxide varistor (MOV). The MOV acts as a transient suppressor, diverting excess voltage away from the normally open (NO) terminals and the power return terminals. This feature helps protect the relay contacts from damage caused by sudden voltage surges, ensuring their longevity and reliability.
• The relay outputs in the module also incorporate a failsafe feature. In the event of a cable being unplugged or a loss of communication with the associated I/O processor, the failsafe mechanism activates. This feature intelligently de-energizes the corresponding relay, ensuring a safe and controlled response to the loss of communication. The failsafe functionality adds an extra layer of protection and helps prevent unintended or unsafe operations when communication is disrupted.

FREQUENTLY ASKED QUESTIONS

What is IS230TNRLH2E?
It is a Relay Output DIN-Rail Module manufactured and designed by General Electric

What is the purpose of the terminal board in the Mark VIe I/O modules?
The terminal board is a critical component that mounts to the control cabinet. It serves as a connection point for the I/O signals and provides the necessary interface between the external devices or sensors and the I/O pack. There are two basic types of terminal boards: S and T. They differ in their configuration and functionality.

What is the difference between the S-type and T-type terminal boards?
The S-type terminal board features a single set of screws for each I/O point, allowing a single I/O pack to condition and digitize the signal. This board is utilized for simplex, dual, and dedicated triple modular redundant (TMR) inputs. Depending on the redundancy requirement, one, two, or three S-type boards may be used.
