Terminal Blocks - Headers, Plugs and Sockets are a type of electrical component used commonly in industrial, commercial and residential establishments for secure and convenient mounting and connection of wires and cables. The use of Terminal Blocks is essential in many electrical applications as they provide a mechanical connection and electrical insulation to protect against short-circuits, prevent unwanted contact with live parts and facilitate the safe and efficient distribution of power around a room or facility. The ELVR13100 belongs to this family of components, and its application field and working principle will be detailed in this article.

The ELVR13100 is a Voltage Relay (Type B) designed for the measurement of mains voltage. It relays an adjustable preset signal when mains voltage value falls within preset limits. It has a segregated and replaceable timing circuit module to control the contact switch-on time delay. This makes it useful for a range of electrical applications, such as early warning systems in industry, peak load management and switchgear monitoring. It also supports protection from surge and overvoltage events. The ELVR13100 is especially suitable for applications in noisy environments or where severe operating conditions are present, as it features an isolation box with safety terminal strips.

The construction of the ELVR13100 consists of two main components: a plastic encapsulated measured contact relay module and a time delay module. The relay module houses the primary input, which connects to the mains voltage, and the secondary output, which connects to the voltage regulator. This is then connected to the time delay module, which contains the circuit board and resistors. The resistors are connected to the time delay pot terminals and the power supply terminals, which are used to adjust the time delay range settings. The power is supplied by the input of the voltage regulator connected to the mains voltage.

In operation, the ELVR13100 measures the mains voltage and generates a signal when it falls within a preset range. This signal is then used to actuate a contact switch, which can be used to trigger an alarm or turn devices on/off. The adjustable time delay module is used to set the delay duration for the actuator of the contact switch. This is convenient for applications that require timed control over equipment, and helps ensure the correct switching happens at the right moment.

In conclusion, the ELVR13100 Voltage Relay is a reliable and versatile component designed for the measurement of mains voltage and the control of contact switch-on time delay. It is suitable for use in noisy environments and offers the added benefits of surge protection and peak load management. This makes it an ideal solution for industrial, commercial and residential electrical applications.
