The SUMMIT is a 6-channel 16-bit DAC and 24-channel high drive digital I/O.

SUMMIT

The Summit is a six channel analog output card with 16-bit resolution. In addition, the Summit provides 24-lines of high current digital I/O. It is designed for use in systems where high reliability is of utmost importance while operating in harsh environments.

Each analog output range is individually configurable to ±10V, ±5V, 0-5V or 0-10V.

Analog (DAC) output transfers can be setup for individual or simultaneous through either software or a hardware input strobe configurations.

Software compatibility is important because it immediately offers third party driver support as well as second sourcing. The Summit is compatible with several other ISA cards including Measurement Computing CIO-DDA06/16 and Keithley DDA-06. It is also a combined DAC06 and DIO24 rolled into one.

8255 Software compatible interface structure provides one 8255 compatible I/O ports that provides 24-lines of general purpose digital I/O.

High-current digital outputs 65mA sink and 15mA source. This is true even while operating at high temperatures.

Direct interfacing to OPTO-22’s isolated I/O racks. Digital I/O connector is organized to allow direct connection to OPTO-22’s isolated I/O racks including the G4 series, the PB16-H, PB16-J, PB16-K, PB16-L, PB8H and the PB24HQ.

Single +5V Supply Operation means reduced power supply and system level complexities.

LED status indicator. An LED displays card activity which is useful for both product development and field service status. By looking at the LED you can quickly determine system status with no tools required.

PC/104 Data bus width. Either 8- or 16-bit data paths are possible for the analog outputs. 16-bit data path effectively doubles the PC/104 bandwidth.

FPGA customization available. We are always able to offer FPGA customization to any of our standard products to meet your exact program requirements.
