156 Converter

Single Channel Optical Converter

The single channel 156 converter is designed for the control of an optek AF56 / AS56 optical sensor or probe for process monitoring. Range settings and configurable alarms add flexibility in the process control. Analogue signals can be passed e.g., to PLC.

Used For

  • For one NIR Absorption sensor (Turbidity)
    • Turbidity (EN ISO 27027)
    • CU (concentration units)

The 156 converter provides continuous inline, real-time measurement and control of concentrations, color changes or turbidity in a variety of industrial processes. With four fixed measuring ranges and one variable measuring range, the converter can be set to match your specific process parameters. The 3-digit LED indicator displays the percentage of the selected measuring range. Two independent set points and one mA output are provided for alarms and real-time process monitoring when wired to the plant's process control system. An additional failsafe relay output is built in for remote sensing of lamp or power failure. Combined with a precision sensor, the converters are cost-effective measuring systems that provide reliable measurements throughout your process.
