The Analog I/O Board is an accessory board that allows the implementation of an analog interface to Elexol’s IO24 Controller Range.
The board consists of an 8 channel, 10 bit Analog to Digital Converter (MCP3008) and a 12 bit Digital to Analog Converter with 2 buffered outputs (MCP4922). Communication to the A/D and D/A Converters is via the SPI interface of the IO24 Controller Module.
The 8 channels of the A/D, 2 channels outputs of the D/A, and all the VREF voltages are connected to screw terminals for easy access. These screw terminals will accept cables 0.5 – 2mm. The connection between the IO24 Controller Module and the Analog I/O board is via a 30 cm IDC connection cable. This cable is provided with the board.
The board has been designed to a 72mm standard width so that it can easily be mounted in DIN rail mounting modules.
