Proportional amplifier, 1-channel

The amplifier is used to control proportional valves. For this purpose, nominal values (voltage signals) from 0 V to +10 V are transformed into the necessary magnetic current for the proportional valves. In FluidSIM the amplifier is coupled to the respective valve with the help of a label. The maximum current at the amplifier output is hereby automatically adjusted in relation to the coupled valve. A step current relative to the maximum current can be specified, in order to compensate the positive overlap of proportional valves. The amplifier requires a power supply of 24 V.
