GE IS200TRLYH1BHH IS200TRLYH1B Mark Vie Relay Output Terminal Board

GE IS200TRLYH1BHH and IS200TRLYH1B are relay output terminal boards for Mark VI and Mark VIe series turbine control systems. The relevant introduction is as follows:

Functional characteristics:

Signal output control: Provides digital output signals for various control and monitoring applications. Through the control logic interface with the system, the relay is turned on or off to control external devices such as pumps, valves and alarms, etc., which can control the operation of steam turbines in power generation facilities and ensure safe shutdown.

Relay characteristics: The socket-type sealed mechanical relay is equipped with MOV (metal oxide varistor) suppression function, which can protect the relay and related circuits from voltage spikes and other effects, and improve the reliability and stability of the module.

Multiple application modes: Supports application modes such as simplex, duplex and triple mode redundancy (TMR). In simplex mode, the control signal is transmitted through the JA1 connector and the feedback voltage is monitored; in TMR mode, the relay control signal is input from three connected VME board racks through the JT1, JR1 and JS1 plugs, and the signal controls the corresponding relay driver after voting.

Physical characteristics: The IS200TRLYH1B has 2 large black terminal blocks on the left edge, with a total of 48 barrier terminals, each with a white logo. There are 4 connector ports on the right border, 3 of which are vertically aligned and 1 is parallel to the bottom port. There is a row of relays near the center with a transparent cube cover, and black round transistors and red MOVs on both sides of the relays.

Technical parameters: The input voltage is generally 24V DC, which may vary depending on the installation requirements. There are usually 8 or more relay outputs, and there is a galvanic isolation function between the input and output to enhance anti-interference ability and system security. Communication is usually carried out through GE's proprietary protocol.

Installation method: Support DIN rail or panel mounting, convenient installation in equipment such as industrial control cabinets, and adapt to different installation environments and needs.

Environmental adaptability: It has certain environmental adaptability and is suitable for use in harsh industrial environments. It can work stably within a certain temperature and humidity range, and can meet the complex environmental requirements of industrial equipment sites such as gas turbines.
