Bosch Rexorth Module for monitoring and limiting the solenoid currents with proportional valves RexrothUseThe VT-MUXA2-2 module can be used to monitor 1 or 2 solenoid circuits. The solenoid currents are limited so that there is no overheating of the solenoids. The solenoid currents necessary for operating the valve are provided by an amplifier (order separately).The amplifier is adjusted according to the rated current data of the solenoid (rated current = 1.03 A). With a command value presetting of 10 V, it provides an output current of 1.0 A.In case of defect or incorrect operation, the amplifier may provide a current of more than 1.0 A. The interconnected VT-MUXA2-2 monitoring module recognizes the over-current, reduces the command value or switches off the solenoid current.The VT-MUXA2-2 monitoring module must be protected against voltage peaks from the 24 V mains. Our VT 11110 capacitor module protects against voltage peaks and smooths the 24 V supply voltage.Explosion hazard in case of incorrect assembly!Please observe the following rules under any circumstances!The Rexroth electronics listed in this data sheet must be installed and operated outside the potentially explosive area.The VT-MUXA2-2 module must be switched between amplifier output and solenoids and between control output (command value presetting by superior control) and amplifier input (see block diagram).Only connect valve solenoids the maximum current of which complies with the monitoring current of the VT-MUXA2-2 monitoring module.Notice:The VT-MUXA2-2 module is an electrostatically endangered component. It has to be assembled complying with ESD protective measures.Component series 1X
