3.2 USER INPUT WIRING
Sinking Logic
USR COMM Connect external switching device between the
USR User Input terminal and User Input Common.
The user input of the meter is
internally pulled up to +9 to +28 V
with 10 K resistance. The input is
active when it is pulled low (<0 .7 V).
3.3 INPUT WIRING
PWR COMMON
+9-28 VDC
Thermocouple

CAUTION : Power input common and sensor input common are NOT isolated
from user input common. In order to preserve the safety of the meter
application, the power input common and the sensor input common must
be suitably isolated from hazardous live earth referenced voltages; or input
common must be at protective earth ground potential. If not, hazardous live
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 common; and the common
of the isolated plug-in cards with respect to input common.
