The LPD350 is a compact, cost-effective, 3½-character LCD digital display designed specifically for current loop signals. With its intrinsically safe digital display, the LDP450F is suitable for installation in the field. It is equipped with a 4½-character LCD display which can be read even under poor lighting conditions. The loop-powered (two-wire) design allows for any supply of the digital display via the 4 – 20 mA current loop. No additional wiring is needed for a power supply. The current loop will be interrupted and the display will be looped directly into the circuit.
