Frequently Asked Questions

What is the CRYDOM H12D4840D dual solid state relay used for?

The CRYDOM H12D4840D is a surface-mounted dual solid state relay used for switching AC loads in industrial automation, HVAC, and process control systems. Its SCR output handles up to 40 A at 48 to 530V AC, making it suitable for heaters, motors, and lighting where reliable, noiseless switching is required.

What are the specifications of the CRYDOM H12D4840D relay?

The CRYDOM H12D4840D is a DC-controlled, AC-output dual solid state relay with a Form A (normally open) switch configuration. It delivers up to 40 A at 48 to 530V AC, uses SCR technology, and is surface mounted. It is not finger-safe and requires a heat sink for operation.

Where to buy the CRYDOM H12D4840D relay worldwide?

3G Electric supplies the CRYDOM H12D4840D dual solid state relay to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this SCR-based AC output relay.

How to install the CRYDOM H12D4840D solid state relay?

Mount the CRYDOM H12D4840D on a flat surface using the provided holes. Always attach an appropriately sized heat sink with thermal compound, as operation without one is not recommended. Wire the DC control input and AC load per the wiring diagram, ensuring voltage and current do not exceed 530V AC and 40 A.
