LOOP-POWERED ISOLATORS - TxIsoLoop-1 &TxIsoLoop-2 - 1

LOOP-POWERED ISOLATORS - TxIsoLoop-1 & TxIsoLoop-2 INTRODUCTION Loop isolators provide signal protection by electrically isolating the input signal from the output. TxIsoLoop-1 and TxIsoLoop-2 simplify your application and avoid the undesirable ground loops by providing single and dual loop galvanic isolation. The 0/4-20 mA input is measured and an identical isolated signal is reproduced at the output. Power is drawn from the 0(4)-20 mA input loop, thus no auxiliaty power or an external power supply is needed. ! Input/output galvanic isolation ! Input Signal (INPUT): 0 to 20 mA; 4 to 20 mA (check ! ! No need for power supply ! Powered from the input loop ! Calibration free. High accuracy minimum current for proper operation) Maximum Input voltage (Vin max.): 32 Vdc Voltage Drop (Vdrop): < 3 Vdc Output Signal (OUTPUT): 0(4) to 20 mA Max. Load (RL): 1450 R Accuracy: 0.2 % FS @ 0 a 60 °C / RL= 250 R; 0.3 % FS @ -20 a 75 °C / RL= 250 R Operating current: > 0.1 mA Overload: < 40 mA; < 32 Vdc Response time: 2 ms @ RL= 250 R Isolation: 3000 Vac / 10 s; 240 Vac continuous EMC: EN 61326-1 Ambient temperature range: -20 to + 75 °C Humidity: 20 to 90 % RH Protection: IP40 Wire gauge for connections: 0.14 to 1.5 mm² Recommended torque: 0.8 Nm Terminal blocks injected in Polyamide BLOCK DIAGRAMS CHANNEL 1 NOVUS AUTOMATION INC.
