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.
Micro PLCs such as the Lovato LRK20RD024RS provide programmable logic, timing, counting and signal-processing functions within a compact controller. The combination of digital inputs, configurable analogue inputs and relay outputs allows the unit to monitor sensors and switches while controlling contactors, valves, alarms and other automation equipment.
Built-in Ethernet and RS485 connectivity makes the LRK20RD024RS particularly useful in connected automation systems where communication with HMIs, supervisory equipment or other controllers is required. Expansion using Lovato LRE modules increases total system capacity to 44 I/O points, allowing the controller to support applications ranging from simple machine functions to more complex distributed control tasks.
