M22-FW-24A

In the field of Panel Indicators, Pilot Lights, the M22-FW-24A is one product which is favored by many. Its wide application field and complex working principle are factors that have made this product to become a common choice.

M22-FW-24A is mainly used to indicate operation states, errors and running conditions of electric equipments, e.g. for machines, pumps and other industrial equipments. The products are applicable to all kinds of AC or DC voltages. The main purpose of this product is to indicate when the equipment is in a running state, when it is in a paused state, when it needs maintenance, when it is in a closed state or needs resetting, when it shut down due to an error, and other conditions. By displaying different colors of lights, M22-FW-24A can provide visual feedback when the equipment is running.

The working principle of the M22-FW-24A is quite complex. It consists of a light source (LED, or Light Emitting Diode) and a control circuit. The control circuit of M22-FW-24A mainly includes a voltage sensor, a voltage dropping capacitor, a transistor amplifier, a voltage signal shunt, and a light driving circuit. The power supply will be connected to the voltage sensor and the light-emitting diode in the circuit, which will be powered up. The amplitude of the input voltage signal will be monitored and compared by the voltage sensor circuit, and if the input signal reaches the over-voltage point, the voltage dropping capacitor in the circuit will discharge to reduce the input signal voltage and protect the circuit. The voltage signal will then pass to the transistor amplifier, which will be amplified. Next, the voltage signal will be split into two parts: one is connected to the voltage signal shunt and the other one is connected to the light driving circuit. The voltage signal shunt will be sensed and then sent to the light driving circuit to drive the light-emitting diode.

In conclusion, M22-FW-24A can provide visual feedback when the equipment is running. It has wide applications in many industries, such as for machines, pumps, and other industrial equipments. Moreover, the working principle of this product is quite complex and it consists of several components, including a voltage sensor, a voltage dropping capacitor, a transistor amplifier, a voltage signal shunt, and a light driving circuit.
