APPLICATIONS
The DPM 742-BL is powered from the 4-20mA signal loop and needs no other power supply. The LED backlighting requires a
separate d.c. power supply. Ensure correct polarity when connecting.

Backlighting switched on.
Note:
If the backlighting supply voltage (V+ - 0V) = 5V,
then no resistor R is required, and connect BL- to 0V.
