Applications
The MCX240D5 solid state relay is used to switch AC loads up to 5A from low-voltage DC control signals in industrial automation, HVAC systems, and embedded control boards. Its 4000V isolation voltage ensures safe separation between the microcontroller signal domain and mains-voltage load circuits. The zero voltage crossing feature makes it ideal for resistive heating elements and lamp control applications where soft switching reduces electrical noise.

Frequently Asked Questions
What is the maximum load current the MCX240D5 solid state relay can switch?
The MCX240D5 supports a maximum on-state current of 5A, allowing it to control a wide range of AC resistive or inductive loads in industrial and commercial applications without requiring an external power relay or heat sink in low-ambient environments.
How much isolation voltage does the MCX240D5 provide between input and output?
The MCX240D5 offers a maximum isolation voltage of 4000V between control input and load output, providing strong galvanic isolation that protects low-voltage microcontroller circuitry from dangerous mains voltages in AC switching applications.
Can the MCX240D5 be driven directly from a 3.3V microcontroller output?
The MCX240D5 has a control voltage of 3V with a control current of only 15 mA, making it compatible with 3.3V logic outputs from modern microcontrollers and FPGAs without additional driver circuitry in typical control designs.
What advantage does the zero voltage crossing feature offer in resistive heater applications?
Zero voltage crossing switches the AC load only when the sine wave passes through 0V, eliminating inrush current spikes and reducing radiated EMI by up to several dB compared to random-phase switching SSRs in heating and lighting control systems.
