The M453 Analog I/O PMC board is designed to provide analog output and analog input on a cost effective and small industrial standard PMC form factor. The M453 provides a host processor card that has industrial standard PMC slot(s) with multiple channels of high resolution (16-bit) analog inputs and 12-bit analog outputs interfaces. The Analog I/O PMC interface supports 50 external analog input channels and 8 analog output channels. The on board memory provides 128 x 16-bit buffers for each input channel. The analog input channels are converted in series. The conversion time for each analog channel is programmable from 10 to 46 microseconds; from 700 microseconds to 2 milliseconds is the conversion time for of all channels. The User can program a port conversion list if less than all 50 channels are used.
