DPM 742-BL

Specifications liable to change without prior warning

PRODUCT DESCRIPTION

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.

backlighting ensures excellent readability under low light conditions. Connection is via screw terminals. The module's

low cost means it will suit high and low volume applications. 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.
