Name: Festo 538912 Motor controller SFC-DC-VC-3-E-H0-IO
Brand: Festo

Motor controller SFC-DC-VC-3-E-H0-IO

The Festo 538912 is an industrial component featuring a cascade controller operating mode with a P position controller, PI speed controller, and P current regulator, utilizing an encoder position sensor alongside a nominal controller power of 75 W. Comprehensive protective functions include I²t monitoring, current monitoring, voltage failure detection, drag error monitoring, and software end-position detection, supported by electrically isolated digital logic outputs with a maximum current of 500 mA. Powered by a nominal DC voltage of 24 V for both the logic power supply at 0.1 A nominal current and the load supply at 3 A nominal current, the unit operates within a permissible range of ± 10 % and features an RS232 configuration interface operating at 9600 Baud. Housed in an IP54 protection class enclosure compliant with EU-EMV guidelines for the CE symbol, the component withstands shock per DIN EN 60068-2-27 and functions within a storage temperature range of -25 to 60 °C at 0 to 95 % non-condensing relative air humidity.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
