In industrial production or daily life, if the controlled circuits can be turned on or off automatically when certain conditions are met, the normal operation of the whole system can be avoided due to the failure of a single piece of equipment. Relay is a common electrical control device in industrial production and daily life. Honghong monitoring relay can monitor the changes of voltage, current, cosine phi, temperature or liquid level to ensure the reliable operation of the system and promote energy saving.
Surveillance LED Lights

The use of LED lamps has become very common nowadays, and LED lamps can be found in all kinds of buildings, factories and public places. Compared to the power consumption of conventional incandescent and halogen lamps, LED lamps consume less power and are more difficult to monitor. If multiple LED lights are installed in a building or elevator car system, managers need to recognize one or several light faults in time and pass them on to the reporting system in order to ensure reliable lighting.
Honghong Monitoring Relay HK-E1IM1AACL10 is a new type of current monitoring device in the ENYA series for power distribution installation, which can handle low current variations in the range of 50mA to 1A. It is capable of monitoring whether the current is below the set threshold, within the set frequency band or exceeding the upper limit. These functions can be selected using the selector switch and can be used with or without the memory function. To ensure that no alarms are generated at power-up, the unit has an internal timer that hides short-term variations in current from 0.1 to 10 seconds. If the current range defined as "good" is exceeded, the MIN or MAX LED starts blinking.

The Honghong HK-E1IM1AACL10 is optimized for the distributor structure, which can be directly powered by 230VAC supply voltage and can be easily mounted on DIN rails for easy integration into existing systems, saving space and cost.
Voltage monitoring

In self-powered commercial and domestic technical systems, systems with long supply lines or weak energy supplies (remote buildings), anomalies can often be seen directly in the supply voltage. Critical electrical conditions such as undervoltage, asymmetry and phase failure can be easily detected with the Honghong voltage monitoring device HK- E1YM480Y.
These problems are caused by the start-up of various building service systems (e.g. air-conditioning, ventilation systems, heat pumps or elevators). With the HK-E1YM480Y it is possible to measure the voltage of all 3 phases and detect deviations according to the set voltage thresholds. An internal timer is used to define the time at which deviations can be tolerated, thus enabling a delayed switch-off. This means that short deviations do not immediately trigger the switching process. The compact design of the Honghong HK-E1YM480Y allows it to be powered independently of the measurement circuit and is suitable for use with all power distributors.

The compact design of the Honghong HK-E1IM1AACL10 enables reliable voltage, current, cosine phi, temperature or level measurements.
Vacuum Pump Monitoring

A SMD machine is a device that accurately places surface mount components on PCB pads by moving the mounting head. During the operation, the manager needs to monitor the bonder to prevent its vacuum pump rotor from jamming. The Honghong monitoring relay HK-V2IM10AL10 monitors the current to the vacuum pump motor. Once the permissible range is exceeded, such as an overload due to a clogged sheet, the relay output is disconnected and the contactor shuts down the pump. The vacuum sensor on the laminating machine detects the error condition and signals the stopping of the laminating process.

The HK-V2IM10AL10 supports 24 - 240 V AC/DC power supply voltage and can be used to monitor voltage, current, cosine phi, temperature, and other parameters, making it very powerful.
