VT-SSPA Plugin Proportional Amplifiers

Indramat VT-SSPA Plug-In Proportional Amplifiers are 24 VDC valve-mounted amplifier units used to operate solenoid-actuated pressure-control and directional valves without closed-loop position feedback. The amplifier converts a command signal into proportional solenoid current, using a 0…10 V range for proportional control and a higher command range for switching-style operation at regulated maximum current. Adjustment options allow the output behavior to be matched to the valve, including zero or bias current setting, maximum-current attenuation, independent ramp-up and ramp-down timing, and dither frequency tuning. The units mount directly to valve connection bases built to EN 175301-803 and can be rotated in 90° steps for flexible cable routing and installation. Connection options include cable-gland versions and M12 component-connector versions. Across the series, nominal current ratings range from 0.8 A to 2.5 A, supporting different proportional valve and solenoid requirements.
