18 Metering & Protection Panel Mount Indicators OM-LCD-LP digit 2-wire loop powered indicator The second generation OM-LCD-LP microprocessor based panel 2-wire loop powered display has been designed to be accommodated in shallow panel installations. The OM-LCD-LP is a digit indicator with a high contrast LCD display with 12.7mm digits to ensure excellent visibility. All function settings and calibration is achieved by user programmable pushbuttons (pushbutton functions include decimal point, digital filter, resolution, square root extractor etc.). The display is fully scalable to read in engineering units. The OM-LCD-LP is supplied factory calibrated and computer tested. Since the instrument utilises pushbutton setup it can be scaled and configured without test equipment or the need to dismantle to select components.

In the self-powered version the system voltage provides both power supply and an input to the voltage modulation circuit of an oscillator. Square wave pulses from a multi-vibrator circuit with a mark-space ratio varied by the measured voltage, and amplitude varied by the measured current, are fed to an integrator and an output amplifier circuit. The DC milliamp signal produced is therefore directly proportional to the power input. All inputs are isolated by the use of transformers. For large voltage variations use the auxiliary powered versions. Self-powered units permit voltage variations up to +20% of the nominal input. Measures both import and export power.
