Клапан amplifiers Для servo-клапаны VT 11021-1X

Description Component series 1X Analog, Modular design For valves: 4WS2EM 6-2X, 4WS2EM 10-5X and 4WS2EM 16-2X Features Differential input for voltage Output stage with dither signal Reverse polarity protection for the operating voltage Product description The amplifier module is snapped onto top hat rails according to EN 60715. The electrical connection is established via screw terminals. The module is operated with 24 V direct voltage. The command value ±10 V is connected to the differential input. The output current of the downstream U/I converter controls the servo valve. At the trimming potentiometers Gw, Zw and GD, the following external settings are possible: Max. output current with "Gw" Offset current with "Zw" Amplitude of the dither signal with "GD" Type code 01 Valve amplifier for servo valves without electrical position feedback, analog, modular design, for valves 4WS2EM 6-2X and 4WS2EM 10-5x VT 11021 02 Component series 10 ... 19 (10 ... 19: unchanged installation and connection dimensions) 1X 03 Further details in the plain text * 01 02 03 VT 11021 ‒ 1X / * Technical data General Component series 1X Type of electronics Analog Design Modul Voltage supply Operating voltage Nominal U V 24 Lower limit value UB(t)min V 21 Upper limit value UB(t)max V 35 Power consumption P VA 8 Current consumption max.
