Solid State Relays

Solid State Relays, or SSRs, are modern replacement relays for traditional electromechanical relays. Unlike the traditional relay, a solid state relay does not contain moving parts; instead, it has an integrated circuit that controls the switch. Solid State Relays are used in a wide range of applications, including motor control, sensing, switching, as well as general-purpose and specialized applications.

PS7113L-1A-E4-A Application Field and Working Principle

The PS7113L-1A-E4-A is a Solid State Relay designed for use in light-load/high-current applications. It is especially suitable for panels with tight installation areas that require a small form factor. The relay provides 4 channels and can switch up to 3A per channel, with a maximum voltage rating of 250VAC. It is specifically used for applications such as temperature control, motor speed control, light dimming, and pulse-width modulation.

The PS7113L-1A-E4-A has an input voltage range from 3V to 32V and a maximum switching power of 70W per channel. It features protection from reverse polarity, over-voltage, and short-circuit. The relay is designed with a dustproof and waterproof shell, and is also resistant to vibrations. It has an MTBF of 221k hours and a life expectancy of 100k cycles.

The working principle of the PS7113L-1A-E4-A is based on switching the current in the load circuit through an internal MOSFET. It uses an input voltage to activate the internal circuitry, which switches the current in the control circuit. This switch, in turn, is connected to the load circuit, which can be a motor or light source, and the current then switches to the load circuit. The PS7113L-1A-E4-A is designed with an over-current and temperature protection circuit and is rated to hold up to 70W per channel.

The PS7113L-1A-E4-A is an ideal choice for applications that require a low-profile, high-efficiency Solid State Relay with protection from both reverse polarity and over-voltage. Its compact size and high power ratings make it an ideal choice for tight installation areas, while its high level of protection ensures that the relay will remain safe and reliable in operation.
