System Overview

The 84903020 system consists of a relay unit and controller unit. The relay unit is used to detect and switch off an overload or undervoltage condition. The controller unit is used for monitoring the system and performing the appropriate action according to the set parameters. The system is equipped with a number of inputs and outputs (I/O) including current, voltage, relay outputs, and alarm lamps. The unit supports a range of current and voltage sensing, enabling the user to modify the settings if required. The system supports a variety of alarm levels and trips, allowing the user to tailor the system to their requirements.

Current and Voltage Sensing

The 84903020 feature current and voltage sensing systems that are designed to sense both single and three-phase AC current and voltage. The voltage and current sensing function is designed to detect any changes in the power supply that may occur as a result of overvoltage, undervoltage, or overload. The system can detect a range of voltages ranging from single-phase 120V to three-phase 480V. The current sensing range is from 10A to 630A. The unit is designed to trip the relay when an overload or overvoltage occurs. The unit also has a warning LED that is activated when an alarm condition is detected.

Relay Outputs

The 84903020 features relay outputs that can be used to control the connected loads. These relay outputs are designed to be used to switch equipment on and off as required. The system is capable of performing a variety of control tasks, including the automatic switching on and off of the load according to the set parameters. The system also supports a range of time-delay functions that allow the user to set the delay between the time the relay is switched on and when the load is switched off. This feature allows the user to optimize the system performance and prevent unnecessary tripping.

Alarm Lamps

The 84903020 also features a range of alarm lamps. These lamps are used to indicate an overload or overvoltage condition. The alarm lamps are designed to alert the user to the presence of an overload or overvoltage condition and provide the user with a warning that the system needs to be shut down. The lamps can also be used in a variety of applications, such as protecting an overloaded motor.
