Solid State Relays

VOR2142B8 Application field and Working Principle

A solid state relay (SSR) is an electronic switching device that controls a load without relying on physical contact. In contrast to conventional relays, SSRs use semiconductor switching elements such as thyristors, triacs, or transistors. The VOR2142B8 solid state relay is a rugged and durable industrial grade device.

The primary application field of the VOR2142B8 is process temperature control or temperature measurement, where accurate control of heated elements and processes is needed. It can also be used to control other electronics such as fans, pumps, and motors. With a wide operational voltage range of 5V to 240V AC or DC, the VOR2142B8 can be used in a variety of applications.

The power dissipation of the VOR2142B8 is rated at 25W, which makes it suitable for controlling an array of loads, from small resistive loads to large inductive loads. It also features a number of protective features, including over-temperature protection and short-circuit protection, as well as a zero-crossing switch-on and switch-off function.

The working principle of the VOR2142B8 is based on the SCR (silicon-controlled rectifier) triggering technology. It is composed of a switching element, such as a triac, and a separate thermal management module, which is tasked with thermal management to prevent overheating. When the voltage is applied to the switching element, it will cause the switch to turn on or off. The thermal management module will monitor the temperature and adjust the voltage accordingly, ensuring that the VOR2142B8 operates within the specified temperature range.

The VOR2142B8 is a reliable and cost-effective solution for controlling a variety of electronic loads. Its robust design, wide operating voltage range, and protective features make it an ideal choice for industrial applications where accurate and reliable control and monitoring are required.
