Solid state relays (SSRs) are electronic devices that use semiconductor switching technology instead of electro-mechanical contact switching. The MCTC2490JRDs are high-performance, cost-effective SSRs. They employ GaAs infrared (IR) emitting diode light or visible red LED to provide optical coupling between input and output. They switch loads using zero voltage switching (ZVS) for high-efficiency operation and maximum durability.

The MCTC2490JRDs are designed for use in applications such as solid-state lighting, motor control, power supplies, contactors, and other applications requiring fast switching. This SSR has a wide range of applications due to its low on-state resistance, high input-to-output isolation voltage, and high EMI/RFI immunity.

The MCTC2490JRD SSR utilizes an SCR (silicon-controlled rectifier) triggered by a signal from the LED light. The light acts as a controllable source of current, which creates an oscillating current in the AC line. This current will cause the SCR to turn on or off. When the SCR is turned on, the load will be powered. When the SCR is turned off, the power to the load will be removed. This enables fast switching with minimal AC distortion and no contact bounce.

In addition, the MCTC2490JRD is designed for use with PoE (Power-over-Ethernet). This means that its power can be supplied through a single Ethernet cable, eliminating the need for extra power connections. The SSR supports 4KV of isolation voltage, making it suitable for use in industrial and medical applications.

The MCTC2490JRD is a highly reliable, cost-effective SSR for a variety of applications. Its low-noise operation and superior EMI immunity make it ideal for use in challenging environments. Its zero voltage switching capability ensures maximum durability, and its support for PoE eliminates the need for extra power connections.
