7I73 Smart Serial I/O card

The 7I73 is a remote real time pendant or control panel interface. The 7I73 uses a high speed real time RS-422 link for host communications and can support update rates up to 10K updates per second so there is no detectable delay or roughness in the control panel or pendant interface. The 7I73 supports up to four 50KHz encoder inputs for MPGs, 8 digital inputs and 6 digital outputs and up to a 64 Key keypad. If a smaller keypad is used, more digital inputs and outputs become available. Up to eight 0.0V to 3.3V analog inputs are also provided. The 7I73 can drive a 4 line 20 character LCD for local DRO applications. Software contrast control is provided for the LCD. The 7I73 is powered by the same CAT6 cable that provides the data interface. Cable length can be up to 30 Meters. The RS-422 interface at 2.5 MBaud is compatible with HostMot2s SSLBP smart serial interface.
