Solid state relays (SSR) are active electronic components that can be used to control currents and voltages in any type of electrical system. They are typically used in industrial automation, communications, and control systems. The MCTC4850KRA is a member of the MCTC family of SSRs and is designed specifically for use in sensing, switchgear, control and protection applications. This article will provide an overview of the MCTC4850KRA application field and working principle.

Application Field

The MCTC4850KRA is designed for use in AC and DC applications and can be used in a wide range of applications including sensing, switchgear, control and protection applications. The MCTC4850KRA is suitable for switching low level, low voltage AC and DC circuits, such as the control circuits of motors, lighting and alarms. The MCTC4850KRA can be used for applications that require high accuracy and fast response time, such as relays for temperature and pressure measurements, and for switching motor drive systems.

Working Principle

The MCTC4850KRA operates by using a solid-state relay to control the current and voltage in an electrical system. The relay works by using an input signal to control its output. When the input signal is high, the output is high, when the input signal is low, the output is low. This type of operation is known as break-before-make or bbm operation. In this operation mode, the input signal is used to first turn off the current before turning on the desired voltage. This prevents power surges that can otherwise occur when two or more input signals are simultaneously active.

The MCTC4850KRA has an operating temperature range of 0°C - 55°C, a voltage range of 0 - 24Vdc, and a current range of 16A. It is capable of controlling currents up to 20A and voltages up to 24Vdc. The MCTC4850KRA has a hot-swappable design, meaning it can be replaced without having to power down the electrical system. The SSR is also designed with fast turn-off and turn-on speeds, allowing it to be used in applications requiring high accuracy switching.

Conclusion

The MCTC4850KRA is a reliable and versatile solid state relay that can be used in a variety of applications, including sensing, switchgear, control and protection applications. It has low input and output signal levels, a wide operating temperature range, and fast response times. The MCTC4850KRA is an ideal choice for applications requiring reliable, accurate control of voltage and current.
