Q22F1ABXXB220E

Panel indicators, pilot lights, and related devices provide important information to staff or operators about the state of a machine, process, or system at a single glance. A typical indicator may produce a single point of indication for each condition, such as on/off, open/closed, up/down, and/or present/absent. The Q22F1ABXXB220E is one type of panel indicator. This article discusses the application field and working principle of the Q22F1ABXXB220E.

Application Field

The Q22F1ABXXB220E has wide application in the field of industrial automation, marine, and medical devices. It is a waterproof LED indicator that is designed for 3/4 inch mounting hole, perfect to fit into a variety of enclosures.

It is an ideal device for indicating or signaling the monitoring data, alarm states, run/stop status, and any other changes in a variety of applications in which a visual alert signal or indication is required. It is widely used for on/off indication, process line control, alarm status of motor operation, fault differential pressure, overrating operating temperature or a combination of these applications.

Working Principle

The Q22F1ABXXB220E is an LED indicator driven by a low voltage DC power source. It is designed with a 24Vdc constant current source, which provides an accurate and reliable indication status at different operating conditions. This can be verified by the V=R*I product that is derived from a free wheel diode which is connected across the 24Vdc supply and the LED in the circuit.

The unit is designed to be quite simple in its operation, such that all it requires is a power source and an appropriate control signal. The control signal is provided by an independent system that monitors the operational state of a machine or system. This signal is then sent to the LED indicator, which in turn illuminates the LED in the required color. The appropriate color indicates the appropriate status of the monitored system, allowing operators or personnel to quickly identify the system state.

In addition, the Q22F1ABXXB220E is designed with warning, alarm, and emergency control buttons for proper panel indication. The warning button serves as a reminder, informing the operator of the need to take action when certain parameters are exceeded during operation. The alarm and emergency buttons may be used to alert personnel in the event of a malfunction. The LED indication can be seen from each of these buttons, which helps personnel take the necessary action quickly and efficiently.

Conclusion

The Q22F1ABXXB220E LED indicator is an important device for monitoring the status of a machine or system in an industrial automation, marine, or medical setting. It can be used to quickly provide visual information to personnel about any changes in the system state, allowing them to quickly take the necessary action. The working principle of the Q22F1ABXXB220E relies on a low voltage DC power source and an appropriate control signal being sent to the LED indicator, which illuminates the appropriate color to indicate the state of the monitored system.
