NEMA 4X Large Display Loop-Powered Indicator

TEK-LCD 7805A SERIES NEMA 4X Large Display Loop-Powered Indicator

The Tek-LCD 7805A is a plastic, loop-powered process meter with 1″ display digits in a field-mountable enclosure designed for demanding applications. The meter derives all of its power from the 4-20 mA loop with a small 1 V drop, so there is no need to run additional, costly power lines. The Tek-LCD 7805A is built in a NEMA 4X and IP65 rated plastic enclosure which can stand up to even the harshest environmental conditions. It is programmed using four easy-to-access, front-mounted control dials.
