32 Channel USB Relay Module - 24V
It has thirty-two onboard 24V DC relays that can switch up to 7A load. The relays are controlled by USB capable Microchip PIC Microcontroller (PIC18F65J50) and come with built-in firmware that supports simple commands to control relays and read relay status. The board, when attached to a PC/Laptop shows up as a serial port and all you need to control the board is a serial terminal application like HyperTerminal or Putty. This board can easily be controlled by writing a simple serial port application in VC++, VB, VBA (Word, Excel, etc), Perl, Python, etc.
