Solid State Relays

The MCTC4850KLC is a solid state relay (SSR) that is designed to switch electrical loads when exposed to control signals from low voltage sources. SSRs can switch much higher current than traditional mechanical relays, enabling device users to reduce size and weight requirements, as well as increase reliability.

The MCTC4850KLC utilizes a triac to switch an AC load up to 13 amps, and can be controlled by low level signals such as 3-32V DC, 4-20 mA, or even digital signals. The SSR is designed to be mounted onto a standard DIN rail to enable easy assembly into a compatible panel or junction box, and also includes a built-in LED indicator for monitoring and connection checks.

Application Fields

The MCTC4850KLC is designed for applications such as industrial process control, motor load control, conveyor systems, lighting controls, and general power switching. This SSR can also be used in automotive applications such as HVAC control, power door motor control, or lighting control.

Working Principle

The operation of the MCTC4850KLC is based on the simple idea of switching current or voltage on when a control signal is applied. The SSR uses a triac to control the on and off states of the load it is connected to, and is activated by a control signal (3-32V DC, 4-20 mA, or digital) that controls its gate between the MT2 and MT1 terminals. When the control signal is applied, the gate is actuated and the triac turns on, allowing the current or voltage to flow from MT2 to MT1 and power the connected load. When the control signal is removed, the triac will turn off (open) and the load will be disconnected.

The MCTC4850KLC includes LED indicator to let the user know when a current or voltage is connected to the load, and a built-in snubber circuit to prevent spurious or destructive voltage transients. This SSR also features a dielectric strength of 4.5 kVAC for reliable and safe operation.

In summary, the MCTC4850KLC is a solid state relay that is designed for applications where high power switching is required. It uses a triac to switch an AC load up to 13 amps, and is easily controlled by low level signals such as 3-32V DC, 4-20 mA, or digital signals. This SSR also includes a built-in LED indicator for monitoring and connection checks, and features a dielectric strength of 4.5 kVAC for reliable and safe operation.
