SP4-PS

SP4-PS application field and working principle

SP4-PS application field involves the connection of three-phase motors in industrial, refrigeration, and automation applications, thermoelectric plants, heating, etc. It offers safe power on/off control and can be used in different voltage networks operating in AC or DC. Moreover, it works with mechanical, thermal, or magnetic loads.

The working principle of the SP4-PS relay socket is based on the connection of 1 NO contact, 1 NC contact, and an auxiliary contact made with silver alloy if necessary. The socket is composed of a plastic body and a terminal thats built with two electrodes which provide connection for each output. The 1 NO contact is used to control the power on/off; the 1 NC contact is used to control the stop; and the auxiliary contact is used to control the running functions of the equipment or machines.

The SP4-PS has an electronic system that is powered by batteries or an AC voltage and detects the armature current when the device is in operation. This is done by measuring the impedance between the two electrodes. When this impedance is greater than the expected value, the SP4-PS sends an electrical signal through 1 NO contact, 1 NC contact, and the auxiliary contact. This signal will be the stop instruction.

In order to provide a safe and reliable operation, the SP4-PS has a protection system that prevents any overload of voltage or current through the circuit. This protection system is important for ensuring a safe and reliable operation. It helps to prevent any damage to the electrical components or any interruption in the machine’s functioning.

The SP4-PS also has a connection for mounting an electrical switch for manual control. This feature allows the user to control the machine from a distance by supplying power or cutting it off, and it can also be used to control the running modes of the equipment or machines.

The SP4-PS relay socket can be used in various applications such as motor control, heater control, and thermoelectric control. It provides a simple solution to the problem of controlling a variety of electrical loads. It is also easy to install, and provides a safe operation and a reliable connection.
