D1012 Quadruple Repeater Power Supply DIN-Rail Model D1012Q Characteristics: General Description: The quadruple channel DIN Rail Repeater Power Supply D1012Q provides a fully floating dc supply for energizing conventional 2 wires 4-20 mA transmitters located in Hazardous Area, and repeats the current in Safe Area to drive a load. Function: 4 channels I.S. analog input for 2 wires loop powered transmitters, provides isolation between input versus output and supply, and current (source mode) output signal. On demand it is possible to supply the following combination of input/output: 2 independent input // 2+2 independent groups of output or 1 input // 4 outputs. Signalling LED: Power supply indication (green). EMC: Fully compliant with CE marking applicable requirements. Front Panel and Features: • Input from Zone 0 (Zone 20), Division 1, installation in Zone 2, Division 2. • Quadruple channels for 2 wires Transmitters. • 4-20 mA Input, Output Signal. • Input and Output short circuit proof. • High Accuracy. • EMC Compatibility to EN61000-6-2, EN61000-6-4. • ATEX, IECEx, FM & FM-C, Russian Certifications. • Type Approval Certificate DNV and KR for marine applications. • High Reliability, SMD components. • High Density, four channels per unit. • Simplified installation using standard DIN Rail and plug-in terminal blocks. • 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier. Technical Data: Supply: 24 Vdc nom (20 to 30 Vdc) reverse polarity protected, ripple within voltage limits s 5 Vpp. Current consumption @ 24 V: 160 mA with 20 mA output typical. Power dissipation: 2.3 W for 4 channels with 24 V supply voltage and 20 mA output typical. Max. power consumption: at 30 V supply voltage, 4.0 W for 4 channels. Isolation (Test Voltage): I.S. In/Out 1.5 KV; I.S. In/Supply 1.5 KV. Input: 4 to 20 mA (2 wire Tx current limited at = 22 mA). Transmitter line voltage: 14.0 V typical at 20 mA with max. 30 mVrms ripple. Output: 4 to 20 mA, on max. 300 Q load source mode, current limited at 20.6 mA. Response time: 500 ms (10 to 90 % step change). Output ripple: s 30 mVrms. Performance: Ref. Conditions 24 V supply, 250 Q load, 23 ± 1 °C ambient temperature. Calibration accuracy: s ± 0.1 % of full scale. Linearity error: s ± 0.05 % of full scale. Supply voltage influence: s ± 0.05 % of full scale for a min to max supply change. Load influence: s ± 0.05 % of full scale for a 0 to 100 % load resistance change. Temperature influence: s ± 0.01 % on zero and span for a 1 °C change. Compatibility: /* £ CE mark compliant, conforms to 94/9/EC Atex Directive and to V. ^ 2004/108/CE EMC Directive.
