USB Relay Boards
The IA-3000-U Series are a low-cost range of USB relay boards, digital I/O units and Analog I/O modules for desk-top, panel mount or Industrial DIN rail mounting. They feature mains rated relays of up to 240VAC 8Amp,  as well as signal multiplexing modules, powering and controlling up to 16 relays per board. Highest density boards includes 32 relays per board, they are USB controlled, too, but they are powered by a standad 24V DC power supply.

All IA-3000-U, USB Relay Boards has a Virtual COM Port structure, so that they can be used with most legacy software packages, and they also include an API software DLL package, as well as Open Source sample programs, for those customers that prefer developing their own software. 

Each IA-3000 Series board is provided with a wide literature package on CD, that includes the product's dedicated User Manual, with a detailed software and hardware installation guide, including several wiring options, when applicable. 

Most software programs that can send or receive ASCII data to an RS232 port, are suitable to operate the IA-3000-U modules. Typical programs that can be used are Windows HyperTerminal  emulator,  MXTTY, as well as GenieDAQ, ADAMView, LabVIEW, DasyLab, TestPoint and more.
