MESA 7I70The MESA 7I70 is a 48 point remote isolated field input card designed for fast real time PC based control systems. The 7I70 communicates with the host with a robust isolated RS-422 link. Standard CAT5 cables are used for wiring convenience. The 7I70 is supported by Mesa's low cost FPGA cards which present a simple parallel register interface to the host, with all protocol details handled by the smart interface. One FPGA card can support up to 32 external devices and up to 3072 control points while still maintaining a 10 kHz service rate for all points. The 7I70 has 48 DC voltage sensing inputs. The 7I70 inputs are smart with variable threshold sensing. Default input threshold is 50% of field power voltage with 20% hysteresis but input thresholds are individually programmable from 0 VDC to 36 VDC. All inputs have LED status indicators and removable screw terminal field wiring. The 7I70 is suited for high performance industrial automation and machine tool applications.

Price of the 7I70 in 100's is $57.
