Description

Relay LED indicator lamp detection device

Technical Field

Background

A relay is an electronic control device having a control system (also called an input loop) and a controlled system (also called an output loop), which is commonly used in automatic control circuits, and which is actually an "automatic switch" that uses a small current to control a large current. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. Due to the particularity of the control type relay, in order to quickly distinguish the working state of the relay in the electric control cabinet, an LED indicating lamp is usually arranged inside the relay and used for indicating the working or non-working of the relay.

At present, there are two more common LED pilot lamp mounting methods: one is that the LED indicator light is connected in parallel to a working coil of the relay after passing through a series current-limiting resistor; the other is that a tap is pulled out of a relay coil, and the tap is directly connected in parallel to an LED indicator lamp after voltage division. Because the coil of the relay supplies power, two specifications exist: direct current and alternating current; and the direct current is divided into direct current forward direction and direct current reverse direction; the voltage is divided into three parts according to voltage grades, and the voltage is basically distributed between 3V and 380V. The LED is a current device, light emission is related to current, and the current is generally between 5 and 20 mA; the relay is mostly a voltage type device and is related to voltage; therefore, the structure of the series current-limiting resistor is adopted, the size of the resistor depends on the rated working voltage of the relay, and the structure of the tap shunt is adopted and depends on the number of turns of the coil. When the produced resistor is abnormal or the number of turns of the coil is wrong, the LED is abnormal in light emitting and even the quality accident of the relay is directly influenced.
