DIRT220A is a type of rack-mounted contact output monitor that is used to monitor current and voltage over a wide range of applications. This monitor is available in two models, namely, model DIRT220A and DIRT230A. With its robust, durable and reliable design, it is suitable for many applications such as industrial, HVAC, lighting, security and marine applications, just to name a few.

The DIRT220A monitor consists of an LCD display, multiple display modes, DMX and analog input ports, as well as relay and open collector outputs which can be configured based on application requirements. It operates on 12V to 24V DC power supply, and provides protection for input signal thanks to its overvoltage, undervoltage, and overcurrent protection. It is also capable of handling analogue signals up to 4-20mA and providing a 4-20mA output. The device is IP65 rated, making it suitable for indoor and outdoor use. It also has two additional channels for monitoring battery voltage, temperature and/or humidity.

At the heart of the device is an advanced non-volatile microprocessor which is used to continuously monitor and protect the applied voltage and current. The processor can be programmed to continuously monitor average, peak, and minimum values on both the input and output signals. It can also be configured for overvoltage, overcurrent, and over temperature protection, as well as for indications to alert the user when the applied voltage or current exceeds the configured limits. Furthermore, the device also offers several options for the user to select from a range of auto-detect modes to calculate the current and voltage values for the specific application.

The outputs of the device include relay outputs which can be selectively configured in relation to low, normal or high voltage settings. This allows the user to control the connected load by controlling the voltage or current set on the device. The outputs also include open collector outputs which can be used for DC applications. The outputs can be controlled through analogue or digital signals, allowing the device to be integrated with external controllers.

Overall, the DIRT220A is a very versatile and reliable monitor that is suitable for a wide range of current and voltage applications. It offers robust design and protection features, with a wide range of output options including both analogue and digital signals. Its its easy to configure user-friendly interface also makes it suitable for applications where the user needs to set their own parameters for monitoring and protection.
