Field output card designed for fast real time PC based control systems
The MESA 7I71 is a 48 point remote isolated field output card designed for fast real time PC based control systems. The 7I71 communicates with the host with a robust isolated RS-422 link. Standard CAT5 cables are used for wiring convenience. The 7I71 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 7I71 has 48 sourcing 5VDC to 28VDC power drivers with up to 300 mA load capability. All outputs are short circuit protected and driver chips have thermal protection. Short circuit and thermal shutdown status is provided to the host. All outputs have clamps to allow driving inductive loads, LED output status indicators, and removable screw terminal field wiring. The 7I71 is suited for high performance industrial automation and machine tool applications.
Price of the 7I71 in 100's is $86.00.
