NeoTecMaster, Slaves and Signal Converters – Reliable Interfaces for Precise Measurement Data
In modern water treatment and process plants, accurate acquisition, processing, and transmission of measurement data are essential. Our NeoTecMaster products, Slaves, and signal converters provide the ideal solution for integrating different sensors into existing systems.
Signal converters with 4–20 mA or Modbus interfaces ensure safe and interference-free transmission of measurement signals over long distances, while remaining fully compatible with common control and monitoring systems. This enables efficient integration of key parameters such as pH, Redox, chlorine, or conductivity into digital monitoring platforms.
Whether as a master control unit, slave extension, or signal converter – these components are indispensable for process safety, seamless system integration, and accurate data transmission. They enable centralized control, reduce installation complexity, and support sustainable optimization of water analysis operations.
The calibration box is used for the calibration of Modbus sensors. The wires from the sensors are connected to the terminal block on the front of the box and the Box is connected to a computer via a USB interface.Advantages:Simple and safe calibration of the Modbus sensors

The NeoTec Slave 2/3/4G is designed for use in control and regulation systems with decentralised I/O nodes. It consists of CAN field bus components, all of which are designed for top-hat rail mounting and are graduated in snap-in widths of 22.5 mm. It is also possible to route both the CAN bus and the power supply through a bus strip integrated into the top-hat rail. The extensive product portfolio of over 100 different fieldbus components enables solutions with conventional I/Os through to communication with standardised industry-typical fieldbus protocols. Thanks to the modular design, the components can be easily retrofitted. The I/O modules are mainly available in units of 2, 4 and 8 I/Os. The integration of the busbar into the top-hat rail ensures user-friendly, time-saving and safe wiring.
The use of the NeoTec Slave 4-20 mA allows to process up to six external 4-20 mA measuring signals. Via the additional four outputs which are defined as 4x 0-10V or 2x 0-10V + 2x 4-20mA, the data can be transferred process-specific to downstream components.Advantages:inversion of the input signals on the assigned outputs possible (e.g. for concentration-dependent pump control) compact design for top hat rail mounting when using several modules, only one power supply is necessary addition of a further module for application integration possible
The use of the NeoTec Slave 4-20 mA allows to process up to eight external 4-20 mA measuring signals. Advantages:inversion of the input signals on the assigned outputs possible (e.g. for concentration-dependent pump control) compact design for top hat rail mounting when using several modules, only one power supply is necessary addition of a further module for application integration possible
By using these NeoTec Slave relay modules, potential-free relay contacts are added to the overall system. All relay contacts can be freely assigned to the incoming measuring signals and can therefore be used, for example, for limit value-related control concepts or measured value-related messages.Advantages:individual implementation of: alarm message based on received measured values and/or status messages switching contacts for simple valve control compact design for top hat rail mounting when using several modules only one power supply is necessary modular expandable according to process requirements
