540039

Name: Festo 540039 Motor controller SFC-LAC-VD-10-E-H2-IO
Brand: Festo

Motor controller SFC-LAC-VD-10-E-H2-IO

The Festo 540039 is an industrial component featuring an adaptive status controller operating mode, an integrated mains filter, and an encoder rotor position sensor. It delivers a nominal controller power of 480 VA at a nominal DC load voltage of 48 V and a nominal load current of 10 A, backed by protective functions including I²t monitoring, current monitoring, voltage failure detection, drag error monitoring, and software end-position detection. System configuration and commissioning are handled via an RS232 interface operating at 38400 Baud, while user interaction is facilitated through a 128 x 64 pixel graphical LCD display and four control elements.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Engineering context

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.
