MemoRail Modbus A1405N Compact Multiparameter Transmitter | Memosens Sensors | Modbus RTU | 1 Channel

Description

MemoRail Modbus A1405N Compact Multiparameter Transmitter | Memosens Sensors | Modbus RTU | 1 Channel

Compact Multiparameter Measuring Device for Memosens and Digital Sensors.

MemoRail Modbus is a space-saving transmitter with Modbus RTU interface in a 17.5 mm modular housing. Available as a 1- or 2-channel version for operation with contactless Memosens sensors as well as the SE680 digital conductivity sensor and the SE740 optical oxygen sensor.

  • 1-channel version
  • Slim modular housing with 17.5 mm width
  • Memosens communication
  • With pH/ORP combo 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

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

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

Red and green LEDs report the operating and sensor states. 1- and 2-channel versions are available to optimally suit your application.

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.

Memosens and Digital Sensors
The use of digital sensors and Memosens sensors with contactless Memosens technology ensures maximum reliability and availability of the measuring point.

MemoRail Modbus is ready to use immediately after a Memosens or digital sensor is connected.

We look forward to hearing from you!
