sc200™ Universal Controller

One Hach Controller for the Broadest Range of Sensors

The Hach sc200™ universal controller works with up to 29 digital or analog sensors for up to 15 different parameters.

SC200 Controller

Build Your Own sc200

The sc200 Universal Controller is the most versatile controller on the market. It allows the use of digital and analog sensors, either alone or in combination, to provide compatibility with the broadest range of sensors.

  • Replaces the Hach sc100™ digital and GLI53 analog controllers with advanced features for easier operator use.
  • Configurable to operate either 2 Digital Sensor Inputs, or 1 or 2 Analog Sensor Inputs, or a combination of Digital and Analog Sensor Inputs. Configure Now
  • Communication options include MODBUS RTU and Profibus DPV1.

Key Benefits

Maximum Versatility

  • Standardized controller eliminates the need for a variety of dedicated controllers
  • Multi-channel controller operates either 1 or 2 sensors reducing inventory holding costs and providing an inexpensive option to add a second sensor at a later time
  • "Plug and Play" operation with all Hach digital sensors
  • True dual sensor controller provides 4-20 mA outputs to transmit primary and secondary measurement values

Ease of Use and Confidence in Results

  • New display and guided calibration procedures reduce operator error
  • Password protected SD card reader offers a simple solution for data download and transfer
  • Visual warning system provides critical alerts

Communication Options

  • MODBUS RS232/RS485 or Profibus DPV1
