The 1M Servo Amplifier Cards series is a family of electronic amplifier units used to control proportional hydraulic valves, especially pressure-control valves that operate without position feedback.
The documented versions include compact Eurocard-format amplifier cards and related module variants, with an approximate 100 × 160 × 35 mm format, DIN 41612 F32 plug connection, and a nominal 24 VDC supply. Depending on the model, the output stage is sized for either 0.8 A / 20 VA or 2.5 A / 25 W solenoids, and the cards support functions such as adjustable ramp-up and ramp-down times, PWM output control, rapid solenoid energization, and monitor-signal handling. The series is built for industrial installation with operating temperatures up to 70 °C, short-circuit-protected inputs and outputs, LED status indication, and a valve response time of about 50 ms for a full signal change. The 1M Servo Amplifier Cards series is intended for hydraulic control systems that require compact amplifier electronics with configurable signal shaping for proportional valve actuation.
