2P18U3H/68

2P18U3H/68 is a type of electro-mechanical relay specifically designed for safety circuit applications. It is primarily used in applications where multiple circuits need to be integrated to ensure the safety of all personnel involved in the operation. The relay performs two essential functions: it helps control the switching of the machine from one state to another and it keeps the machine in one of two predetermined states: the “Safe” state or the “Unsafe” state.

The 2P18U3H/68 is characterized by its compact and efficient design. Only three components make up the relay: the switch, the current limiter, and the contactor. The power supply can be either single-phase or three-phase. The contactor is an electromagnetically actuated switch which, when energized, will draw current through the circuit thereby controlling the machine’s circuit state. The current limiter will prevent an excessive surge of current going through the system. These two components allow the 2P18U3H/68 relay to safely switch the machine’s circuits between states.

The 2P18U3H/68 is a popular choice for safety circuits, but is also used in a wide variety of other applications. These include motor control, power monitoring, power measurement, and temperature control. It is often found in large power plants, manufacturing plants, and even in household appliances. As the complexity of a circuit increases, so too does the safety of its personnel and the reliability of the products manufactured. The 2P18U3H/68 is a reliable and affordable safety solution for these applications.

In addition to its use in safety circuits, the 2P18U3H/68 is also used as a timing and logging relay. This is due to the fact that the relay is powered directly from the voltage source and is not dependent on a separate power source. The 2P18U3H/68 is able to record the time it takes for a circuit to go from one state to another and then store that time in memory. This process is used extensively in logging operations and in monitoring how quickly processes are completed. In fact, the 2P18U3H/68 is often the go-to choice for logging relay applications.

The 2P18U3H/68 is also used in applications that require precision control. By using a combination of the current limiter and electromechanically actuated switches, the relay can be used to accurately adjust the currents and voltages passing through a circuit without excessive surge. This precision makes the 2P18U3H/68 a reliable choice in applications such as precision testing, medical imaging, and semiconductor fabrication.

Overall, the 2P18U3H/68 is an incredibly versatile and reliable electro-mechanical relay that can be used in a wide variety of applications. Its small size and low cost makes it an excellent choice for safety circuits as well as applications that require precise timing and precision control. As reliability and safety continue to be important areas of focus for technology, the 2P18U3H/68 will remain a popular choice for applications that require reliable control.
