  • Binary inputs and outputs
  • Analog inputs 4-20 mA (2)
  • Serial communication port for external devices (RS 232/422/485), isolated
  • Data logger with 0,1 sec. resolution
  • RTC Real Time Clock
  • Programmable logic controller (PLC)
  • Modubus RTU communication protocols
  • Removable terminal blocks
  • Easy configuration software

The EX-101 is a extension module for MT family of telemetry modules. It is optimized for use in advanced measurement systems equipped with 12/24V power source. Additionally, it can act as a universal I/O station with galvanically isolated RS232/485/422 Modbus RTU interface.

The ability to run local control program allows to use EX-101 module as freely programmable PLC.

Resources

  • 8 optoisolated binary / counter inputs 24V DC (I1 – I8)
  • 8 configurable binary outputs / inputs / counters 24 V DC (Q1 – Q8)
  • 2 optoisolated analog inputs 4-20 mA (8 bit acc./10 bit res.) with configurable hysteresis and filtration
  • Isolated serial port RS 232/485/422
