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 (see Figure 8). 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 8. Standard Terminal Board

This 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 100 Series

Display option. Refer to section 2.6 Field Wiring for more information about the setup of the Model 100

Terminal Board.

1.4 Model 100 Display Terminal Board (Optional)

If the unit is ordered with the optional display or a battery pack (as used in wireless configurations) the unit

comes with the Model 100 Display Terminal Board mounted in the J-Box (See Figure 9).
