Box T239

The box provides an interface between the computer and the process to automate. You can connect directly the sensors (like temperature sensors) and devices to control (like valves, pumps,...). You can configurate the system yourself without any knowledge of computer languages thanks to the user interface (Siam).

Typical applications

• fermentation
• control of chemical reactions
• quality control
• automatisation of measurements at laboratory-, pilotplant- and production-scale
• instruction tool.

Advantages

• easy to adapt to the needs of the process
• easy to learn and to use
• possibilty of following complex control strategies
• all the paramters can be visualised graphically
• storage of the data on hard or floppy disk
• data transfer to any program that uses ASCII code (spreadsheet, word processing programs,...) or direct DDE communication.
• possibility of controlling several processes at the same time, several reactors, several analytical instruments,....

Standard configuration

• 8 configurable analog inputs (0-10 V, 0-20 mA, 4-20 mA, Pt 100, thermoelement), with 24 V available for Pressure probes
• 4 analog configurable outputs (0-10 V, 0-20 mA, 4-20 mA), with 24 V available
• 4 digital inputs, with 24 V available
• 8 digital outputs (relay), with 24 V available
• communication with the PC through RS485 interface. 16 such boxes can be connected on the same line over a distance from 800 m.

We have also solutions for more specific configurations. Please contact us.

Converter 0-10 V - Pulsations (PWM/pulse wide modulator)

This device has been designed to vary the pulse time of a relay with a 0-10 V signal. The pulse frequency (10, 5, 2, 1 0.5, 0.1 Hz) is fixed on the device with a button. The 0-10 V input signal control the time on wich the relay stay at the on state (see figure). The frequency can be visualised on a display.

For exemple if the input signal is 0 V and the frequency 0.5 Hz, the output stays low. If the input signal is 10 V, the signal stays high. If the input signal is 5 V, the output stays 1 second low and 1 second high.

Typical applications

• control of on/off valves
• automation (pressure control with a valve)

Technical description

• input signal: 0-10 V
• output: relay max 2 A, 24 V
• frequency of the output: 10, 5, 2, 1 0.5, 0.1 Hz

NuDam Serie

These are modules with analog and digital inputs and outputs for Din rail mounting. They communicate with the PC through a RS422 or RS485 interface and with our software Siam. Drivers for other software can also be provided (DASYLab, ISA Graf, libraries and driver for MS DOS/Windows 95/98/NT/2000/XP, OPC Server).
