Connecting a T50 Industrial Terminal

You can connect a T50 Industrial Terminal (Cat. No. 1784-T50) to the
1779-KP5 for use on the Data Highway Plus network. To connect the
T50 to the 1779-KP5, you can use a 1784-CP5 cable, or you can construct
a cable using the following pinout:

PowerĆDistribution Guidelines

Allen-Bradley power supplies have circuits that suppress electromagnetic
interference from other equipment. For installations near particularly bad
electrical noise generators, an isolation transformer can provide further
suppression of electromagnetic interference from other equipment.

In applications where the AC power source is subject to unusual
variations, a constant-voltage transformer can stabilize the AC power
source to the interface, thereby minimizing shutdowns.
