The DLMHBRAAA application field and working principle is used in a wide range of current monitoring and voltage relay output applications. This type of device is designed to detect, measure, and, if necessary, operate a relay output in response to an analog signal. The main application areas for DLMHBRAAA are within the electrical/electronic industry such as electrical power, instrumentation, and process control.

DLMHBRAAA detects and measures electrical current in either AC or DC. It is designed to provide reliable and accurate over-current protection, particularly in applications with low impedance or high inrush currents. Differental current sensing is achieved by using two integrated precision bridge amplifiers that measure current in two opposite directions. The outputs from these two amplifiers are summed to provide a differential measurement.

Because of its two bridge amplifiers, DLMHBRAAA can be used to measure both positive and negative AC current, providing versatile applications. The differential current sensing eliminates the need for external bias voltage sources and allows accurate high frequency response. This allows the DLMHBRAAA to be used to monitor both load and line currents, which is extra important in multi-phase applications. When a current exceeds the desired threshold level, the indicated output relay turns off.

The voltage relay output provides an adjustable output on-delay timer and adjustable output off-delay timer. The timer is actuated when a voltage level is below (or above) a preset level. When the voltage returns to its preset level, the timer re-engages. The output stays off for the fixed off-delay period and turns on for the fixed on-delay period. The timer is adjustable, allowing for different applications.

The DLMHBRAAA is ruggedly designed to withstand high temperature and other adverse environmental conditions and offers protections against over-temperature, reverse polarity, and high voltage surge. The device is also certified to IEC/EN 61000-4-2 industrial-level standards, thus making it suitable for use in industrial environments.

The DLMHBRAAA is easy to operate and is designed for applications where precise current monitoring is required. The device features an analog current meter to monitor the current, as well as a digital display for voltage monitoring. It also features an adjustable timer, threshold detection, and adjustable relay output. It is also compatible with a wide range of third-party software and hardware.

In summary, the DLMHBRAAA is a versatile and reliable device for monitoring current and voltage levels, relay output activation, and output delay operations. It features a wide range of input and output voltages, adjustable timers, and adjustable current and voltage outputs. It is designed for industrial environments and is certified to international standards for safety and reliability. This makes the DLMHBRAAA suitable for a variety of industrial and commercial applications.
