Why Choose the Lovato LRK20RD024RS Micro PLC?
The Lovato LRK20RD024RS is a compact and versatile micro PLC base module designed for machine control, automation and building-management applications. It combines 12 inputs, 8 relay outputs, an integrated display and built-in Ethernet and RS485 communications in a single programmable controller.
Powered from 12/24 V DC, the LRK20RD024RS provides eight standard digital inputs plus four inputs that can operate as either digital or 0–10 V analogue inputs. Its eight relay outputs make it suitable for direct switching of a wide range of control circuits, while the integrated Ethernet and RS485 interfaces provide flexible connectivity to automation networks, HMIs and supervisory systems.
The base module supports up to 20 onboard I/O points and can be expanded to a maximum of 44 I/O using compatible Lovato LRE expansion modules. A built-in 4-line × 16-character LCD display, DIN rail or screw mounting and compact enclosure make the LRK20RD024RS a practical solution for standalone automation and distributed control systems.
