Panel Instrument
The DPM 742-BL gives an accurate, zero adjusted indication of a 4-20mA current. Calibration is by two multi-turn potentiometers which allow sensitive adjustment of the instrument over a very wide range. Decimal points are jumper link selectable. A low drift bandgap reference circuit ensures accurate readings over a wide temperature range. LED backlighting ensures excellent readability under low light conditions. Connection is via screw terminals. This module is supplied with a plastic mounting bezel. A waterproof seal to IP67 / NEMA 4X is achievable, using the optional BEZ 700-IP metal bezel. This is a popular part, normally stocked in high quantity and suitable for new designs.
This 4-20mA loop powered panel meter features a 3½ digit LCD with 12.7mm (0.5") digit height and LED backlighting. Calibration is by two multi-turn potentiometers and connection to the current loop is via two screw terminals.
