myDatalogC3e 3mA/6Rel

Output extension myDatalogC3e 3mA/6Rel

The extension module myDatalogC3e 3mA/6Rel is used for signal output of 3 mutually isolated mA (0/4…20 mA) outputs.
Furthermore, it offers 2 groups with a common root with 3 relays each. It is an output extension for devices of the myDatalogC3xx family .

Product features

  • 6x relay outputs for direct switching of loads
  • Relay outputs with max. 230V AC / 30V DC, 2.5kV rated surge voltage
  • 3x isolated mA outputs, galvanic isolation at extra-low voltage level
  • mA outputs with error detection (too high load or cable break)
  • Easy installation thanks to plug-in clamps
  • Compatible with all devices of the myDatalogC3xx family


  • CAN bus as system bus
  • 2x 3 relays with one common root each, contact as normally open with isolating links for 230VAC 3A (no optos)
  • 3x 0/4…20 mA outputs (galvanic isolation at extra-low voltage level)
  • Status LED for power supply, bus communication and relay status

Product configurator

With the help of the runtime calculator, you can estimate the autonomous runtime of the application as well as the costs incurred. The actual costs and energy consumption depend on the measurement conditions, such as the reception quality and ambient temperature. Detailed information on the tariffs can be found here.
