Introducing MemoRail Modbus trans­mitter

MemoRail Modbus is a space-saving trans­mitter with Modbus interface in a 17.5 mm modular housing. Available as a 1- or 2-channel version for operation with con­tactless Memosens sensors.

Versatile Functionality

The compact multi-parameter analyzer supports a variety of process variables:

  • pH
  • ORP
  • Contacting conductivity
  • Inductive conductivity
  • Amperometric oxygen
  • Optical oxygen
  • Temperature


  • Slim modular housing with 17.5 mm width
  • Memosens communication
  • With pH/ORP combination sensors, measurement of up to four process values simultaneously plus temperature
  • Modbus RTU protocol with standard RS-485 interface
  • Up to 32 devices in parallel on a Modbus master
  • Power supply 24 V DC
  • 3-year warranty

Easy to Use

For quick Modbus configuration, the network address is directly set on the MemoRail Modbus devices using the DIP switches on the front panel. 24 V DC is supplied via plug-in terminals or bus connectors.

Universal Use

MemoRail Modbus is an attractively priced solution in process analytics and optimally suited for use in numerous industries:

  • Pharmaceutical industry, biotechnology – Upstream/downstream process – CIP/SIP systems
  • Food & beverage – Process monitoring – CIP/SIP systems
  • Water treatment plants/equipment
  • Power generation, etc.

Because of their narrow modular housing, these DIN rail devices are ideal for installations where space is limited — in fermentation plants and in control cabinets, for example.
