Loop Powered Indicators

The Model 2211-EX Digital Indicator enables the process variables to be displayed locally inside the plant; in any engineering units. These are powered by the 4 -20 mA d.c. signal from a 2-wire transmitter, requiring no external supply or batteries. The drop across the terminals is less than 1V & being non-voltage producing device, can be directly used in hazardous area. The unit is housed in aluminium casted weather-proof / Ex-proof casing. Another model 2211-IS is the panel mounting type.

SALIENT FEATURES :
• 4-20mA d.c. Input. Drop less than 1 V.
• Weather-proof / Ex-proof Al-casted enclosure.
• 3½ digit LCD display.
• Built in reference for easy calibration.
• Any Full Scale Calibration with DIP Switches.
