- DIgITAL PANEL METER wITH RS-485 Measurement of d.c. current or voltage and temperature (Pt100, J, K). Three-colour LED display (5 digits, 14 mm high). digital output RS-485 - Modbus RTU protocol. Two alarm outputs of OC type. Programmable parameters through RS-485 interface using the free eCon software: – recounting of indications (individual characteristic), – two alarms of OC type operating in 6 working modes, – display colour programmable in three intervals, – thresholds of displayed overflows, – highlight of the unit, – automatic or manual compensation: temperature of cold ends (for J, K) or wire resistance (for Pt100), – measurement averaging time. • Additional output 24 V d.c. for supplying of object transducers. EXAMPLE OF APPLICATION Alarms configuration through eCon program Measurement and signalling of temperature overflows or d.c. current galVanic isolation Supply
