Product Description

The CRYDOM Solid State Relay (SKU HA4812, MPN HA4812) is a panel-mounted, AC-output relay with a Form A (SPST-NO) switch configuration. It features a screw-clamp electrical connection, an input current of 10 mA, and an output voltage range of 48 to 530V AC. The relay has a maximum output current of 10 A without a heat sink and is not finger-safe.

Frequently Asked Questions

What is the CRYDOM HA4812 solid state relay used for?

The CRYDOM HA4812 solid state relay is used for switching AC loads in industrial automation, HVAC, and process control systems. It provides reliable, noiseless switching for resistive and inductive loads up to 530V AC, making it suitable for panel-mounted applications where mechanical relay wear is a concern.

What are the specifications of the CRYDOM HA4812 solid state relay?

The CRYDOM HA4812 is a panel-mounted, AC-output solid state relay with a Form A (SPST-NO) switch configuration. It has an input current of 10 mA, output voltage range of 48 to 530V AC, and maximum output current of 10 A without a heat sink. Electrical connection is via screw clamp, and it is not finger-safe.

Where to buy the CRYDOM HA4812 solid state relay worldwide?

You can source the CRYDOM HA4812 solid state relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide competitive pricing and reliable sourcing for this CRYDOM relay.

How to install the CRYDOM HA4812 solid state relay?

Mount the CRYDOM HA4812 on a panel using appropriate hardware. Connect the AC load to the output terminals via the screw clamp, ensuring the output voltage (48 to 530V AC) and current (max 10 A without heat sink) are within limits. Apply the control signal (10 mA input current) to switch the relay. Use a heat sink if exceeding 10 A.
