Overview
The 210 Loop Powered Indicator measures the current of a 4-20mA loop and provides a digital display of the process variable directly in engineering units. The indicator is powered by the 4-20mA loop and requires no external power.
Two potentiometers inside the instrument enable the Span and Zero to be scaled and a DIP switch enables the decimal point position to be selected.
Field mounting by design
The 210 indicator is fully watertight to IP67 (Nema 4X) standards. It is designed for field mounting with a wall mount bracket supplied as standard. A pipe mount bracket is optionally available.
For use in hazardous areas the Model 210i is ATEX certified, and CSAUS/C certified for both the USA & Canada.
Large LCD for easy reading
The 210 incorporates a large, easily read, 4 1/2 digit display. The measurement resolution is 3 1/2 digits and a trailing “0” can be switch selected for applications requiring 4 1/2 digits.
Each indicator is supplied with a sheet of self-adhesive engineering unit labels. A recess, adjacent to the display, is provided for the correct label to be placed. Applications include the display of flow rate, temperature, pressure and a wide range of other signals transmitted over a 4-20mA interface.
