Often referred to as Panel Indicators, Pilot Lights, M22N-BN-TOA-OC is an important tool helping electricians, technicians and engineers in identifying electrical problems in a variety of situations. It is used to monitor the operation of contactor, motor, circuit breaker, power converter, SCR, power transformer, power switchgear and other related equipment. When it is connected to the device being monitored, it will activate and monitor the voltage, current, and other related parameters.

The M22N-BN-TOA-OC determines the voltage, current, and other related parameters of the electrical device monitored in two different operating modes, namely, normal changeover mode (NCM) and negative changeover mode (NCM). In the NCM, the indicator monitors the incoming voltage as well as the current. When a fault occurs, an alarm will activate and indicates a negative changeover. In the NCM, the indicator monitors the current and the incoming voltage, but no alarm will activate. Instead, the indicator will display the fault level on a red LED display.

The M22N-BN-TOA-OC also utilises auto-calibration capabilities, allowing it to self-adjust the fault level, current and voltage measurement points according to the type of the equipment being monitored. The calibration parameters are adjustable, permitting the user to customise the device for the specific application. This ensures accurate and reliable measurements.

The M22N-BN-TOA-OC features a selectable display to optimise the reading accuracy. Three display modes are available: instantaneous, double, and average. In the double display mode, both instantaneous and average values are displayed. This allows the user to track the changes and to identify problems more easily.

The indicator is equipped with adjustable trip points which can be preset for high and low voltage. When the device is used to monitor contactor operation, the trip points can be adjusted according to the contactor’s switching characteristics. This allows the user to select the current value at which the contactor should switch. Additionally, the indicator can be used to detect voltage drift, indicating that the contactor is not aligned correctly and needs readjustment.

The M22N-BN-TOA-OC is designed to be easy to install and operate in a range of industries. It features robust construction and is IP65 rated for protection against dust and water. Additionally, it is designed for reliable performance in wide temperature ranges. Available in several enclosure options, the indicator is suitable for both indoor and outdoor use, making it suitable for a variety of applications.

The M22N-BN-TOA-OC is an important tool for electricians and technicians in identifying electrical problems. With its adjustable calibration features, adjustable trip points, and easy installation, the M22N-BN-TOA-OC is a reliable and efficient indicator for monitoring voltage and current levels. This device is ideal for use in industrial, commercial and residential applications.
