The AN220 servo amplifier is suitable for controlling the most popular servo valves
Linear output stage with three current ranges (±20mA, ±100mA, and ±400mA)
One side of load at zero voltage, allows use as current driver <br> protected against wrong polarity
6 user-selectable voltage inputs (10 k /V), one ±10V input via ramp generator, one 4...20mA input, one differential input
Internal/external modulation limiting for positive and negative valve modulation, adjustment selectable as separate or symmetrical
PID controller with external disable
Control parameters adjustable on the front plate
Ramp has wide range of adjustment (0.1...10sec) and can be disabled externally
