4.3 INPUT WIRING
CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input
common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not,
hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential
of the user input common with respect to earth ground; and the common of the isolated plug-in cards with respect to input common.
AC Inputs From Tach Generators, Etc.

Input A
Current Sinking Output
Input A
Switch or Isolated Transistor; Current Sink
Input A
Current Sink Output; Quad/Direction

Switch or Isolated Transistor; Current Source
Input A
Switch position is application dependent.
Emitter Follower; Current Source
Input A
Current Sink Output; Quad/Direction
Counter A
& Rate B
Counter A &
Counter B
Current Sink Output; Quad/Direction
If you are wiring Input B, connect signal to Terminal 6 instead of 5, and set DIP switches 4, 5, and 6 to the positions shown for 1, 2, and 3.
If using single Counter B, then wire signal to 6,
and Quad/Direction to 8. Set switch positions
4, 5, and 6 as shown for 1, 2, and 3.
