Control Modes

Advanced control flexibility supports on/off, proportional, and PID configurations. This sophisticated programming ensures precise set point regulation for dual-channel operation, eliminating overshoot and reducing chemical usage.

Hold Function

Reliable hold activation can be initiated manually or via external digital input, safely pausing control functions during sensor maintenance or calibration.

Configurable Alarm System

Customizable alarm settings monitor set points, temperature deviations, and operational anomalies. A highly visible blinking red alarm LED alerts users from afar, while all control relays automatically deactivate until the issue is cleared.

Auto-Cleaning Cycle

Programmable sensor cleaning enables scheduled wash cycles that trigger relays to operate valves, pumps, or compressed air systems, maintaining probe cleanliness for accurate and consistent readings.

Relays

Comprehensive relay options include up to five electromechanical control relays plus one dedicated alarm relay for robust process management.

Analog Outputs

Precise analog control is delivered through up to four galvanically isolated 4-20 mA outputs, perfect for accurate dosing pump and valve regulation.

Digital RS485 Output

Efficient network integration allows daisy-chaining of up to 32 devices via RS485 for centralized remote monitoring and control.

Digital Inputs

Versatile external triggers provide two digital inputs to enable functions such as hold mode, cleaning cycles, or temporary control disable.
