  • Narrowbanded, interference-proof, temperature-stable
  • permanent monitoring of radio status
  • Temperature-stable radio module: -30 ° C ... + 75 ° C
  • The radio module complies with EN 300 220


The SECU-DATA M modules are available for transmitting 4-20 mA signals with 12-bit resolution or 16-bit resolution to a receive module SECU-DATA C.
M stands for measuring point. The 4-20 mA current signals of the encoder are digitized and transmitted via radio link to the SECU-DATA C (Control).
The radio-transmitted signals are converted back into 4-20 mA currents and made available at the output for further evaluations.
4-20mA signals are very often used in process control, that is why this module can be used universally for many applications.
