The SBX328 board provides analog signal output for any intelligent board with a SBX I/O Expansion Bus connector.  The single-wide SBX328 plugs directly onto the host board, providing eight independent output channels of analog voltage for meters, programmable power supplies, etc.  Voltage output can be mixed with current loop output for control of popular 4-20 mA industrial control elements.  By using an Intel single chip computer (8041) for refreshing separate sample-hold amplifiers through a single 12-bit DAC, eight channels are contained on a single SBX board for high density and low cost per channel.  High quality analog components provide 12-bit resolution, and slew rates per channel of 0.1V per channel.  Maximum channel update rates are 5KHz on a single channel to 1KHz on all eight channels.
