ADU252 USB Solid-State Relay Interface

( See ADU222, 2-amp 120VAC/DC Version)

The ADU252 USB Solid-State Relay Interface allows control of 2 PhotoMOS SSR outputs via a USB port.  High quality PhotoMOS solid-state relays ( Panasonic AQZ202G ) switch AC or DC loads. Suitable for 5V, 12V, 24V or 48V control applications. This USB Solid-State Relay Interface is easy to use with VB, VB.NET, and Visual C++ via standard HID drivers included with Windows XP,8, or 10.  A mini-driver ( DLL )* is also provided allowing control using standard ASCII commands using familiar readfile , writefile commands.  The ADU252 includes a 10' USB cableand a flange mount enclosure. An optional DIN rail version is available.
