AD116-22D/S, AD116 indicates the design model of the lamp; 22 indicates the installation opening size φ22mm; D indicates the code of different shapes of the same aperture; indicates that the power supply is DC220V, commonly used there are 31, 32, respectively, AC220V, AC380V.
Indicator light reflecting the position of the device state, usually with a light on to indicate that the device is charged, the light off indicates that the device is de-energized; indicator light reflecting the working state of the circuit, usually with a red light on to indicate charged, green light on to indicate no power. To avoid misjudgment, the operation of the light bulb or light-emitting diode should be checked frequently or regularly intact.
The light source using incandescent lamps consists of lamp, bulb, lampshade and connecting wires, etc. Light-emitting diodes are also used as indicators, which are generally installed on the panels of high- and low-voltage power distribution devices, panels, tables and cabinets, certain low-voltage electrical equipment, instruments on the plate or other more conspicuous locations.
Signal indicator light, a device that uses light to monitor the working or position status of circuits and electrical equipment. It is also the most intuitive and unique monitoring component in automation equipment. The main function is usually used to reflect the working state of the circuit (with or without electricity), the working state of electrical equipment (running, outage or test) and position state (closed or disconnected), etc. To remind the operator to deal with the fault in time, or operate a certain function to complete the relevant action
Meaning: Represents safety, normality, readiness (that is, an indication of safe operating conditions or the preparation of mechanical equipment to start).
Function: It is often used to indicate the ready-to-start state of the equipment. All auxiliary components are in the ready-to-use state, various parts are in the start-up state, and the voltage is within the specified range.
Meaning: Represents an alarm or a stop of an abnormal situation (ie, a light alarm for a situation that may be dangerous and requires immediate attention).
Function: It is often used for important parts of the equipment to be cut off by protective appliances, and the temperature exceeds the specified limit.
Meaning: stands for warning (that is, state change or approaching limit value) standby, intervention
Function: It generally reminds the operator to pay attention to the standby or operation status of the equipment, especially the debugging state or the short-term stay state
