This manual explains the use of the alpha CON 200 controller/transmitter, including operation steps, installation methods, and warranty methods.
This manual provides step-by-step instructions for operating and installing the αlpha CON 200 1/8 DIN Conductivity Controller with Temperature Display and Transmitter. It includes sections on safety, front and back panel components, wiring, mounting, calibration, relay configuration, and specifications. The device supports two set points, automatic/manual temperature compensation, and isolated 4-20 mA output for remote monitoring. It is designed for industrial applications and comes with removable terminal blocks and built-in memory backup.
The controller operates on 85–260 VAC or DC, features a 4-digit LED display, and includes two SPDT relays. It supports conductivity ranges from 0.00 to 2000 µS/cm and temperature from -10 to 110°C. Calibration and setup are managed via front-panel buttons, with password protection for configuration changes.
