Freemax MX-S2

Freely programmable controller for control engineering systems.
      Designed for mounting on DIN-rail.
      Has different communication interfaces.

Freemax MX-S2
  • Control of various engineering and process plants by recorded user program

General functions

  • Processing of input signals with recorded by user logic and control of outputs of the controller on the basis of this logic
  •  Maintaining parameter on setpoint value using PID-algorithm
  • The possibility of organizing any functions associated with the work in "real time", including the organization of data archiving
  •  Displays information on the color graphics display


 The possibility to creating on Flash-cards format SD the archive to record analog parameters at specified intervals and discrete parameters and status by the time.
The number of types recorded in the archives of analog parameters is not limited. The number of types of discrete parameters - limited by number 64.
Archive capacity depends on the capacity of Flash-cards.

Communication capabilities

 For communication with other controllers by the interface network , or to be able to enable the controller to dispatch system it provides the following interfaces:

  • RS-485 (MODBUS-RTU and UNIVERS protocols)
  • TP/FT-10 (protocol LonWorks)
  • Ethernet (protocol MODBUS-TCP).

   Is possible simultaneous operation of the Ethernet interface and any of the other two interfaces. But, the controller can not be used as an interface converter.
The RS-485 is installed on the left of the controller as a separate module MI-RS3-485.
Interface TP / F-10 is installed to the left of the controller as a separate module MI-LON2
The Ethernet interface unit is a part of controller.

* The program is created on a computer and transferred to the controller with one of the following ways:

  • Flash-card format SD (Secure Digital)
  • connecting the controller to the computer over a network Ethernet
  • remotely over the Internet in the presence of the controller the static IP-address

** Connecting primary converters with output signal (4-20) мА, possible using the transform block signal BPS - (4-20) mA → (2-10) B.
*** Setting both interfaces RS-485 and TP / FT-10 at the same time is not possible.
