| Isolation Amplifier HE 501 Features Input: 0(4) - 20 mA / 0 - 10 V DC, selectable Output: 0(4) - 20 mA / 0 - 10 V DC, selectable Input, output and mains galvanically separated Modular design Housing for DIN rail mounting 12-pole, 82 x 22.5 x 98.8 mm (h x w x d) Brief Description The active universal isolating amplifier HE 501 serves for the galvanic separation of measuring circuits, which are on different potential. The galvanic isolation is performed between input, output and auxiliary energy (24 V DC). The HE 501 processes input signals within the range of 0 - 20 mA, 4 - 20 mA or 0 - 10 V. With two switches at the top side of the device the input value is defined. The output signal is available at the same time as voltage signal (0 - 10 V) and current signal. With a switch in the front, the output current can be switched between 0 - 20 mA and 4 - 20 mA. The modular structured device allows a clear allocation of measuring circuits and corresponds to the EMV guidelines EN 50081 (Part 1) and EN 50082 (Part 2). www..com DBL\HE501e.PM5 05.07.2007 "HESCH" Schroder GmbH * Industrie-Elektronik * Boschstrae 8 * D-31535 Neustadt Tel. +49 (0) 50 32 / 95 35-0 * Fax +49 (0) 50 32 / 95 35-99 * E-Mail: info@hesch.de * www.hesch.de Technical Data Input Output 0 - 20 mA, 4 - 20 mA or 0 - 10 V DC, selectable with S2, S3 0 - 10 V DC and 0 - 20 mA or 4 - 20 mA switchable with S1 Linearity Error: Temperature Drift: Cut-Off Frequency: Insulation Test Voltage: < 0.2 % of span < 100 ppm/K of span 500 Hz Input / Output Input / Auxiliary Power Output/ Auxiliary Power 2000 V 24 V DC (19 - 30 V) 0 - 50 C DIN rail housing 12-pole, 82 x 22.5 x 98.8 mm (h x w x d) Housing IP 40, Terminals IP 20 EN 50081 Part 1, EN 50082 Part 2 500 V Insulation Test Voltage: Mains Supply: Ambient Temperature: Housing: Class of Protection: Standards: Input 1 2 3 0 ...10 V 0 V switchable with S2, S3 0(4)...20 mA 0...10V 0V S2 S3 0(4)... 20mA Output: 7 8 9 0 ...10 V 0V 0(4)...20mA switchable with S1 0...10V 0V 0(4)... 20mA S1 Auxiliary Energy: 10 0 V www..com 12 + 24 V DC (19 - 30 V) 0V +24 V DC Subject to technical Alterations ! |
