What is the use of IS200VPROH1BCD?

The IS200VPROH1BCD is designed to provide an emergency trip function for the Mark VI system. The VPRO board will also control the 12 relays on the attached TREG board; Nine relays will form three sets of three-to-vote inputs to control the three trip solenids provided by the TRPG and TREG terminal boards. The board also has the ability to provide an independent emergency overspeed protection system. The IS200VPROH1BCD also features backup sync check protection, 9 thermocouple inputs, and 3 analog current inputs for detailed overtemperature protection for gas turbine applications.

Relay is an electrical control element, it is an automatic switch with a small current to control a large current, mainly used to control the opening and closing of the circuit.

The working principle of the IS200VPROH1BCD relay is to use the principle of electromagnetic induction, when the current at the input end passes through the coil, a magnetic field will be generated to attract the iron core, so that the contact at the output end is closed or disconnected. In this way, the purpose of controlling the large current with a small current can be achieved.

There are many types of IS200VPROH1BCD relays, which can be divided into different types according to different classification standards. For example, according to the working principle, it can be divided into electromagnetic relays, thermal relays, solid state relays, etc. According to the use can be divided into intermediate relay, time relay, current relay and so on.

Relays are widely used in power systems, automatic control systems, communication systems, transportation systems and other fields. In the circuit, the relay can be used to realize the automatic control, protection, conversion and other functions of the circuit.

In short, relay is an important electrical control element, it can achieve the purpose of controlling large current with small current, and is widely used in various fields.
