USB Solid-State Relay Interface (5 Amp)

2 Channel


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. 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.
