The solid-state relay (SSR) is an electronic switching device that switches on or off when an external voltage is applied across its terminals. Solid State Relays (SSRs) generally switch high voltage circuits on and off using the low voltage at their control terminals. A solid-state relay (SSR) does not include moving parts, making it less prone to wear and tear and more reliable than a mechanical relay. SSRs are typically used where control signals are produced by digital circuitry, such as microprocessors or programmable logic controllers (PLCs), and AC or DC loads are controlled. Besides industrial controls, lighting controls, HVAC, process controls, and other applications requiring high voltage or high current loads, they are also used to switch loads of high voltage and high current. Solid-state semiconductors utilize semiconductors’ electrical and optical properties instead of moving components to control input-to-output actions.
It is an electronic switching device made of semiconductors with no movable parts. Due to no moving components, it is a Solid State Relay, and thus does not undergo any wear and tear on contact, making it long lasting for up to 100 million operations.

Applications of Solid State Relays
Solid State Relays are more convenient and durable devices as compared to convection switching devices, making them handy in applications. They are most commonly used in applications where frequent and high-frequency switching is needed. Due to its unique advantages, it is used to control AC or DC circuits by allowing smaller inputs to control larger output signals. thus, making them useful in many domestic electronics and industrial motor control applications, as stated below:
BCH Solid State Relays are the most suitable switching systems available today with their longer life, sensitive and faster functions. They are used as an effective and reliable switching mechanism in the majority of electrical systems in both domestic and industrial settings.
BCH Solid State Relay are ideal for an application that requires high switching frequency and can be used in harsh environments like shock, vibration, and dusty environments.
Solid State Relay electronically switches power to a load circuit, and Solid State Relay has no moving parts. Therefore, there is no mechanical wear and tear on contacts. The life expectancy of Solid State Relay is over 100 million operations.
BCH Solid State Relay is widely used in heating control, Motor control, capacitor switching and lighting control, solenoid, transformer control, and air conditioning applications.
The BCH electronic switching device is used for external voltage (AC or DC) for controlling terminals. While serving the same functions as an electromechanical relay, expect moving parts. Solid State Relay differs from a general relay, does not contain any mechanical contacts, and mostly uses electronic parts. Thus, Solid State Relays have wide features.
BCH Solid State Relay ranges from 12A to 125A. In which single-phase and three-phase Solid State Relay are available with low-level output control without interfacing. Its narrow Solid State Relay range has current monitoring & temperature controller PID with high switching frequency and longer life. Solid relay has a compact size that has input voltage 3 to 32VDC while other voltages are on request.
