When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the electrical appliance that makes the controlled output circuit on or off can be divided into electrical quantity (such as current, voltage, frequency, power, etc.) relay HKE and Non-electricity (such as temperature, pressure, speed, etc.) relay HKE two categories, with fast action, stable work, long service life, small size, etc., widely used in power protection, automation, motion, remote control, measurement and communication devices middle.
relay HKE is an electronic control device, it has a control system (also known as input circuit) and a controlled system (also known as output circuit), usually used in automatic control circuits, it actually uses a smaller current to control a larger A kind of "automatic switch" of large current, so it plays the role of automatic adjustment, safety protection, conversion circuit and so on in the circuit.
According to the working principle or structural characteristics of relay HKE, it can be divided into electromagnetic relay, thermal dry reed relay, solid state relay (SSR), etc. These three are more common for us, and the common ones are 8 pins or 14 pins, and 8 pins Pin: two sets of normally open, two sets of normally closed, one coil contact, 16 pins: four sets of normally open, four sets of normally closed, one coil contact.
