Description

The ADU218 USB Solid-State Relay I/O Interface allows control of 8 SSR outputs, 8 contact or TTL inputs, and 8 event counters via a USB port. The ADU218 can effectively convert a standard PC to a powerful PLC (programmable logic controller). High quality PhotoMOS solid-state relays switch AC or DC loads. This low-cost serial relay contact interface is easy to use with VB, VB.NET, C, Python, MATLAB, LABView etc. 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 ADU218 includes a 10' USB cable and is available as a PCB or in an enclosure with several mounting options.
