E-BM-AS drivers can drive up to two single or one double solenoid proportional valves. The E-BM-AS are off-board, digital basic drivers in DIN rail format designed for valves without transducer.
Format type: DIN rail, power supply: 24 VDC (standard) or 12 VDC
Digital drivers control the current to the solenoid of proportional valves without transducer, according to the electronic reference input signal. The solenoid proportionally transforms the current into a force, acting on the valve spool or poppet, against a reacting spring, thus providing the hydraulic regulation. The hydraulic regulation means regulation of flow (velocity) or pressure (moment or force of a mechanical system).
