    Product Datasheet: Crydom CX Series Solid-State Relays

  • Product Description:

    The Crydom CX240D5 is a compact, printed circuit board (PCB) mount solid state relay capable of switching a 5 amp load at line voltages between 12Vac and 280Vac. They are ideally suited for high-density applications requiring relatively high-power switching in a compact environment. The CX240D5 utilizes rugged back-to-back SCRs (inverse-parallel) to switch load current, which enables them to perform reliably for millions of hours in even the harshest industrial applications. The typical MTBF for the CX240D5 is >7 million hours.


    The input of the CX240D5 accepts control signals between 3Vdc and 15Vdc and pulls <15mA @ 5Vdc. An internal optical isolator provides 4kVrms dielectric protection between the AC mains and personnel / control circuitry


    The CX240D5 has a zero-crossing output. When an input signal is applied, the solid state relay will not conduct load current until the AC mains passes through the zero-crossing point of the sine wave. This greatly minimizes surge currents and reduces the level of conducted emissions generated by the solid state relay.


    The CX240D5 is also available in a DIN mount carrier (HBC-11-CX240D5) for applications without a printed circuit board or where only a few individual solid state relays are required. Additional DIN mount PCB solid state relays can be found in the Compact Power Controller section of our website.


    Solder Profile:

    The solder profile must be sufficient to provide adequate solder coverage on all of the pins but not in excess of the maximum ratings of the solid state relay

    Wave Solder; Maximum 260°C for 10 seconds

    Hand Solder; Maximum 400°C for 3 to 5 seconds

    Reflow; Not suitable for reflow


    Pin Forming:

    Bending the pins on the solid state relay can damage internal components. Please contact us if you require special forming of the pins.


    PCB Traces:

    The output of the CX240D5 utilizes discrete SCR die capable of withstanding high surge currents. In many applications, the capabilities of the solid state relay will exceed the capabilities of the traces on the printed circuit board. The load characteristics, environment and fault-protection requirements must be taken into consideration when designing the PCB.
