2.7.2 4 to 20 mA Output Connections

A continuous analog current loop output is available for each of the 4 lamp monitor channels in the
MultiBrite System. The 40 to 20 mA output signal is capable of driving a resistive load up to 250 ohms.
Connections to the output should be made using a twisted pair cable. The 4 to 20 mA output is a
continuous analog representation of the relative intensity of the lamp being monitored. The current loop
signal is directly proportional to the percentage reading on the front panel display. 4 to 20 mA
corresponds to 0 to 100% on the display.
