Introduction

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 slots with multiple high resolution, 16-bit analog input and 12-bit analog output channel interfaces.

The analog I/O PMC interface supports 50 external analog input channels and 8 analog output channels, while the onboard memory provides 128 x 16-bit buffers for each input channel. The analog input channels are converted in series with a programmable conversion time from 10 to 46 microseconds for each channel, with a total conversion time from 700 microseconds to 2 milliseconds for all channels. Users can program a port conversion list if less than all 50 channels are used.
