.*
1 = mA, 2 = Pt100, 3 = mA- isolating transformer
1.2. Areas of application
The units can not be operated in hazardous areas.
The maximum permissible ambient temperature is +60 °C.
The minimum permissible ambient temperature is -20 °C.
Two current outputs (4 to 20 mA) and six contacts are controlled depending
several functions. Up to six control signals can be fed to the controller.
As input variants are current input or Pt 100 input available. The input can be
linearised by the software.
The units can be configured and controlled via a serial interface (MODBUS).
Access to the various program levels can be protected by a numerical code.
The units are supplied in a panel mount housing (IP20) with external
dimensions of 72 mm x 144 mm.
