24V dc ControlNet Redundant Media Adapter Cat. No. 1794-ACNR15 13
24V dc ControlNet Redundant Media Adapter Cat. No. 1794-ACNR15
Wiring
1. Connect the ControlNet network cable to connector A.
2. Connect the redundant ControlNet network cable to connector
B.
When using the 1794-ACNR15 as a single channel, use channel
A.
3. Connect +24V dc input to the left side of the lower connector,
terminal D.
4. Connect 24V common to the left side of the upper connector,
terminal C.
5. Connections E and F are used to pass 24V dc power (F) and
24V common (E) to the next module in the series (if required).
6. Set the network address using the 2-position thumbwheel
switch G. Valid setting range from 01 to 99. Press either the +
or - buttons to change the number.
ATTENTION
!
When connecting wiring, torque terminal screws C,
D, E, and F to 7-9 inch-pounds.
