Controller M1


The Con­troller M1 is a smaller, more pow­er­ful, and more eco­nom­i­cal con­troller.
In ad­di­tion to the com­pact timer relay other com­pact ver­sions are also avail­able: im­pulse re­lays, tog­gle re­lays, flasher units and, on re­quest, de­vices with cus­tomer-de­fined func­tionality. The stan­dard op­tions stated above are in­cluded by de­fault and just need to be ac­ti­vated and con­fig­ured. Of course all stan­dard func­tions can also be or­dered pre­set di­rectly from the fac­tory.



  1. MSP430 16-bit micro controller with flash technology (can be re-programmed many times)
  • 1 digital input and 1 digital output
  • Relay contacts in versions S2 and S3 are completely potential-free which supports AC voltage switching
  • Low quiescent current of 1 mA
  • Standard functions and parameters can easily be modified with the programming station
  • More complex applications can be realized with C code
  • Quick implementation of customer requirements
  • Special programs are available on request
  • Housing dimensions 30 x 30 x 40 mm. Please refer to the section housings and base plates for additional housing options.
