How to Install Your Incremental Encoder Module

Publication 1794ĆUM015B-EN-P - May 2001

Methods of wiring the terminal base units are shown in the
illustration below.

Wiring the TerminalBase Units (1794ĆTB3G shown)

Wiring when totalcurrent draw is less than 10A

Wiring when totalcurrent draw is greater than 10A

DaisyĆchaining

Individual

Totalcurrent draw through any base unit must not be greater than 10A

Combination

24V dc

Note: Usethis configuration if using any

noisy" dc digital I/O modules in your system.

incrementalencoder Module wiring separate from digitalwiring.

Note: All modules powered by the same power supply

must be pulse, frequency or TC/RTD/mV modules for this configuration.
