Solid-state relay reference design offers remote, wireless AC power switching

August 15, 2013 // By Jean-Pierre Joosting
Zilog, now part of IXYS, has introduced its ZAURA Reference Design to expand its portfolio of digital wireless solutions that target the industry need for wireless connectivity in control and sensing, for power metering applications, and to eliminate standby power consumption.

This reference design integrates Zilog’s ZAURA RF 868 MHz wireless module onto a current-sensing power SSR. The product is designed to showcase wireless control of an AC power SSR. The IXYS ICD power SSR, with part number CPC1966, features AC zero-crossing detection to minimise surge currents and sine wave distortions. This reference design can be used as a basis for developing systems that can control different power products.

On its own, without the ZAURA RF wireless 868 MHz module attached, this design’s Base Power Board functions as a development board to provide current to power the module and the switch. With the Module attached and controlled by a hand-held remote control device, RF communication can turn a load on and off. To demonstrate RF control, a hand-held ZAURA RF remote control device is also included with this reference design. Documentation supplied provides specifications and schematics, describes its software commands, and also provides a procedure for quickly getting started with development.
