Advanced Pump Automation

Minilecs microprocessor-based system is engineered for smart control of up to three pumps in various applications. It enables automated start/stop sequences, dry run protection, and water level management, reducing manual intervention and operational risks. The auto/manual/test modes empower users to operate, check or override the system as necessary, ensuring optimal performance and safety.


Flexible Installation and Connectivity

The device accommodates both DIN rail and surface mounting, making it suitable for diverse installation scenarios. Its compact design, combined with screw terminal connections and front panel controls, simplifies integration into existing setups, whether for new projects or retrofit jobs. LED status indicators keep operators informed of system health at a glance.


Reliable Monitoring and Fault Logging

Featuring basic inbuilt fault indication and status logging, this pump automation system delivers real-time awareness of operating states and potential faults. When abnormal conditions are detected, users are alerted through both audio and visual alarms, helping avoid downtime and enhancing preventative maintenance processes.
