MCTC2490JHA

Solid State Relays

Solid state relays are electronic switching devices that are used to switch electrical circuits in response to control signals and maintain circuit isolation. These devices are built using components of semiconductor materials including transistors, MOSFETs, and thyristors. As a result, solid state relays are capable of switching thyristors at a much higher speed than traditional electromechanical relays and they can also be controlled accurately and reliably.

The MCTC2490JHA is a two-channel, dual-output solid state relay. It is designed to provide a wide range of switching applications for both AC and DC loads. The device is capable of switching up to 480VAC and 2A of current, and it has an optical isolator for protecting the input and output circuits. The MCTC2490JHA is constructed with an advanced power transistor technology to provide reliable and consistent switching performance.

Application Field

The MCTC2490JHA has two channels, allowing it to control multiple loads at the same time. It is an ideal choice for applications such as lighting control, electric vehicles, home automation and industrial process control. It is also suitable for applications where high inrush and fast switching times are required. In addition, the MCTC2490JHA can be used in temperature, pressure, humidity and flow control applications.

Working Principle

The MCTC2490JHA operates in two modes: light-on and dark-on. In light-on mode, the device is activated when the light is applied to it. Conversely, in dark-on mode, the device is activated when the light is removed. The MCTC2490JHA also includes an electronic LED for indicating the status of the device. Each of the two channels of the MCTC2490JHA has an independent opto-coupler for input protection.

The MCTC2490JHA has three operational states: off, idle, and ON. In the off state, no current flows between the power pins of the relay. In the idle state, the relay is switched on but there is no current flowing. In the ON state, current flows between the power pins of the relay. When either of the two channels is activated, the opto-coupled LED lights, indicating that the power is on. This device is capable of switching two channels simultaneously.

Conclusion

The MCTC2490JHA is a two-channel solid state relay designed for a wide range of switching applications. It is equipped with an advanced power transistor technology and optical isolation for input and output circuits. It can be used for a variety of applications such as lighting control, electric vehicles, home automation, industrial process control, and temperature, pressure, and humidity control. The device operates in light-on or dark-on modes and is capable of switching two channels simultaneously.
