Усилители клапанов для высокодинамичных клапанов VT-KRRA2-527-2X

Description Component series 2X Analog, Euro-card format For valves: 4WRPH 6…L-2X Features Double card for simultaneous operation of two high-response valves Controlled output stage Enable input Short-circuit-proof outputs Adjustable zero point Cable break detection for actual value cable Product description Applications 2-axis control in presses, forming machines and machine tools. Plug-in connections 2 x DIN 41612, 32-pole, for low-power signals (command value, enable, etc.). Screw-plug-in connection to the valve and for supply voltage on handle side (ST 4, 5 and ST 9, 10) included in the scope of delivery. Test points IC base on handle side for control measurements and signal inputs. Displays For cable break, enable and undervoltage. Direct voltage controller (DC/DC converter) For the supply of command value encoders, position transducers and internal supply together for both channels.
