FIXED RANGE TRANSMITTER FOR POTENTIOMETER GENERAL DESCRIPTION The transmitter DAT 205 2W is designed to provide on output a 4÷20 mA current loop linearised signal proportional with the variation of resistance introduced from the potentiometer connected to its input; to make the measure, a 1 Vdc voltage reference is provided at the ends of the potentiometer. The regulation of the zero and full-scale value are made using the ZERO and SPAN potentiometers; there is not influence between the regulations. FEATURES - Input for potentiometer - Zero and Span values adjustable by potentiometers - Independent...

FIXED RANGE TRANSMITTER FOR mV,V AND mA SIGNALS GENERAL DESCRIPTION The transmitter DAT 207 2W is designed to provide on output a 4÷20 mA current loop signal proportional with the variation of the normalised current or voltage signal applied to its input. FEATURES - Input for current or voltage signals - DAT 207A 2W to measure voltage signals included between 0 ÷ 5 mV and 0 ÷ 200 mV; Zero and Span values adjustable by potentiometers Independent Zero and Span adjustment 4÷20 mA current loop output High accuracy EMC compliant – CE mark Suitable for DIN rail mounting in compliance with EN-50022...

SELF-POWERED CURRENT LOOP ISOLATOR GENERAL DESCRIPTION The transmitter DAT 511 is a passive 0÷20 mA current loop isolator. The input current, variable from 0 up to 20 mA, is converted in an output current of the same value but keeping a galvanic isolation from the input circuit. The converter is a passive isolator: this means that the device employs the measurement signal to power it self, so it does not require any external power supply. FEATURES - 0÷20 mA isolated conversion - No external supply required - 3000 Vac galvanic isolation - Good accuracy and performance stability - EMC compliant...
