LoDi-Operator 4-WD-AC

The LoDi Operator 4-WD-AC is a reliable switch decoder for AC voltage, ideal for solenoid and motor-driven turnout mechanisms. It allows precise switching of up to 4 turnouts or signals using true AC voltage—a key advantage over many other decoders that use only DC voltage, which can cause unwanted residual magnetism in solenoid coils.

Technical Highlights of the LoDi Operator 4-WD-AC

✅ 8-channel AC decoder for the SC-Bus, compatible with the LoDi Shift Commander
✅ Designed for 14V – 22V AC voltage
✅ Each output supports up to 1A (total load max. 2A)
✅ Ideal for solenoid drives, motor turnouts & signal control
✅ Prevents residual magnetism and provides demagnetization for coil drives
✅ Individual overload protection per output for maximum safety
✅ Also suitable for stopping sections & other AC-powered devices
✅ Easy configuration via LoDi ProgrammerFX

Why AC Voltage?

Most solenoid turnout motors on the market are designed to operate with AC voltage. However, many standard decoders use DC voltage, which can lead to unwanted magnetization (remanence) in the coil. The LoDi Operator 4-WD-AC supplies true AC voltage, ensuring your drives switch smoothly and reliably—with no long-term side effects.

Versatile Application

In addition to controlling turnouts and signals, the LoDi Operator 4-WD-AC can also switch other AC-powered components, such as stopping sections, older solenoid drives, or lighting elements.

Simple Installation & Operation

The LoDi Operator 4-WD-AC is specifically designed for use with the SC-Bus and is controlled via the LoDi Shift Commander. Configuration is done easily via the LoDi ProgrammerFX, allowing for quick and convenient customization.
