1.3 Model 100 Standard Terminal Board (Optional)
If the sensor is ordered with an explosion proof condulet/junction box, the sensor will come with the Model
100 Standard Terminal Board mounted in the J-Box (Figure 7). This terminal board affords the user easy plug-
in connectors for use in wiring the unit during installation, and convenient test points for measuring the
milliamp (mA) output.

Figure 7 DM Standard Terminal Board
The standard terminal board provides an easy Digital Volt Meter (DVM) connection for reading the mA output
from the sensor. Two test points (TP1 and TP2) provide a connection across a 10Ω resistor that develops a
10mV voltage drop per 1mA output. Thus a reading of 40mV on a DVM equals 4mA of current. This is an
alternative method to reading the mA output of the sensor for assemblies that do not include the DM-100
Series Display option. Refer to Section 2.6, Field Wiring for more information about the setup of the DM-100
Terminal Board.
1.4 DM-100 Display Terminal Board (Optional)
If the unit is ordered with the optional display or a battery pack (wireless configurations) the unit comes with
the DM-100 Display Terminal Board mounted in the J-Box (Figure 8).
