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.
