Lovato ME024RSD024 is a 2.4 A electronic reversing motor starter with a 40–500 V AC operational range, 24 V DC auxiliary supply, adjustable Class 10A thermal motor protection and built-in SIL 3 / PL e Safe Torque Off functionality.
£247.74
The Lovato ME024RSD024 is a compact electronic reversing motor starter with integrated STO (Safe Torque Off), designed to provide forward/reverse motor control, electronic switching and motor thermal protection in a single device. It has a rated operational current of 2.4 A AC-3 / AC-53a and supports operational voltages from 40–500 V AC.
Unlike conventional reversing arrangements that require multiple electromechanical contactors and interlocking components, the ME024RSD024 integrates the reversing function electronically. Its built-in Class 10A thermal motor protection has an adjustable trip range of 0.18–2.4 A, allowing the starter to be configured for the rated current of the connected motor.
For safety-related machine applications, the ME024RSD024 incorporates a Safe Torque Off (STO) function rated to SIL 3 according to IEC 61508 and Performance Level e according to ISO 13849-1. A 24 V DC auxiliary and control supply, diagnostic outputs and compact construction make it a versatile solution for modern industrial automation and machine-control systems.
The ME024RSD024 combines several functions traditionally implemented using separate motor-control components. Electronic forward/reverse switching provides the reversing function, while the integrated Class 10A thermal protection monitors the motor load and can be adjusted from 0.18–2.4 A to suit the connected motor.
Its integrated STO safety function provides a means of preventing torque generation when correctly incorporated into the machine safety system. With safety capability up to SIL 3 and PL e, the ME024RSD024 is particularly suited to modern machinery where compact motor control and safety-related stopping functions need to be coordinated within the automation architecture.

The ME024RSD024 is a 2.4 A electronic reversing motor starter with integrated Class 10A thermal motor protection and a built-in STO (Safe Torque Off) safety function.
The integrated thermal protection has an adjustable trip range of 0.18–2.4 A, allowing it to be matched to a suitable motor within this range.
The motor-side rated operational voltage range is 40–500 V AC at 50/60 Hz, while the starter requires a 24 V DC auxiliary and control supply.
Yes. The ME024RSD024 incorporates a built-in STO safety function with safety capability up to SIL 3 according to IEC 61508 and PL e according to ISO 13849-1.
The starter provides three outputs: one relay output with a changeover contact and two 24 V DC PNP digital outputs for signalling and control-system integration.
Lovato ME electronic motor starters provide machine builders and automation engineers with compact solutions that integrate motor switching, reversing, thermal protection and functional-safety capabilities for modern industrial machinery.
