• 7I84 Isolated remote field I/O card

The 7I84 is a remote isolated 32 input and 16 output digital I/O card. The 16 outputs are 5VDC to 28VDC sourcing drivers  with  300 mA maximum current capability. Outputs have per output short circuit protection, overvoltage clamps and per driver chip thermal shutdown. The 7I84s outputs are suitable for driving relays, contactors, solenoids, and other medium power inductive or resistive loads. The 7I84 uses field power of 5VDC to 28VDC and sets its default input threshhold to 50% of field power supply voltage with 10% hysteresis for noise immunity. 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,  four input pin voltages are readable with 8 bit resolution.  Two MPG encoder inputs are provided as an option on four  field inputs. Field voltage can be split so that each half of the 7I84 uses a different voltage source for the outputs and reference voltage for the inputs, allowing mixed voltage I/O support. The inputs, outputs, and field power are galvanically isolated from the communications link.  The RS-422 interface at 2.5 MBaud is compatible with HostMot2s SSLBP smart serial interface which can support as many as 32 7I84 cards for a total of 1024 inputs and 512 outputs with real time update rates up to 10 KHz. 3.5 mm screw pluggable screw terminals are used for all isolated I/O.
