MSI-4020 Analog Output Card (20 Channel, 12-bit)

The MSI-4020 is a 12-bit analog output card with 8, 12, 16, or 20 channels designed for applications requiring large numbers of outputs for exciting analog output transducers in harsh industrial environments. The card is jumper configurable for output current drives of either ±15 mA using the onboard ±15VDC power supply, or an output current capacity of ±50 mA using an external ±15VDC power supply for powering the output buffer op-amps. Output ranges are individually jumper selectable as 0-5V, 0-10V, ±5V or ±10V for each channel requiring no potentiometer adjustments. In addition, sites for ten optional resistor pairs are available for user supplied voltage divider networks on these outputs. The card is I/O addressed using option jumpers for addresses A2-A9 for specifying the card base address. Up to thirty-one cards can be accessed in a PC/AT system at a single base address requiring a total space of only four I/O addresses. Outputs provided via a 50-pin connector. Requires +5V only.
