7I66-8 oddělovací I/O karta

The 7I66 is a remote isolated digital I/O card. The 7I66 is available in two models, the 7I66-8 (8 output and 16 input) and 7I66-24 (24 output). The 7I66 inputs sense positive inputs relative to a common field ground. Input impedance is 22K Ohms and inputs can range from 5VDC to 32VDC. All I/O pins have LED status indicators. Outputs are sourcing type drivers capable of driving 2.5 A loads. The field I/O points are are galvanically isolated from the communications link. The 7I66 uses field power of 8VDC to 32VDC and sets its default input threshhold to 50% of field power supply voltage with 10% hysteresis. Inputs can be programmed to other thresholds and filtering can be added if desired. In addition to the being able to read digital on/off status of each input, all input pin voltages are readable with 8 bit resolution (7I66-8 only). The RS-422 interface at 2.5M Baud is compatible with HostMot2s SSLBP smart serial interface which can support as many as 32 7I66 cards with real time update rates up to 10 KHz and cable lengths up to 100 feet. 3.5 mm screw pluggable screw terminals are used for all isolated I/O.
