1. Small-Scale Wastewater pH Neutralization
Real-time monitoring and control of chemical neutralization systems where acid or alkaline agents are added to maintain neutral water discharge parameters.
Problem SolvedProvides precise reading of an analog pH sensor (via 4-20mA) and dynamically controls a dosing pump with the built-in analog output, while operating solenoid valves via the high-capacity 2A relay outputs, eliminating the need for expensive external analog expansion blocks.

2. Precision Temperature-Controlled Drying Oven
Regulating heating elements and air circulation systems of a manufacturing oven using industrial thermocouple transmitters and variable frequency drives.
Problem SolvedThe dual 1/6000 high-resolution analog inputs enable reliable dual-zone temperature monitoring. The 0-10V analog output handles fan VFD speeds, and the 2A relay outputs directly trigger heavy-duty contactors to switch the heating elements safely.

3. Municipal Water Storage Level Automation
Automated level monitoring and fill cycle control for a dual-tank storage system in local utility networks.
Problem SolvedSimultaneously tracks levels in two separate tanks using hydrostatic sensors on the built-in analog inputs. The logic commands large pump motor starters with the relay outputs and uses the built-in RS-232C serial port to report alarms directly to an HMI or telemetry modem.
