J54 Digital Inputs
Connector J54 Dig In accommodates up to three digital signals from external
devices. You can use digital input signals to trigger test events with your
controller applications.
• All of the inputs are optically isolated.
• Channel inputs can be 3 volts (minimum) and 26 volts (maximum) from an
external voltage source.
Cable specification
The cabling information shown assumes a single cable destination (with an
overall shield). In other applications, the cable may have more than one
destination. For these applications an overall shield is not practical and non-EMI
connectors and back shells are permissible.
• 9 pin contact type D male EMI connector
• Back shell–EMI metallized plastic
• Cable–shielded twisted pairs as required (24 AWG minimum) with drain
wire(s) connected to the metallized backshell at the chassis.
