UNIT OF REMOTE TONE CONTROL BY STARTER (RTCS) 
 
We are offering two modification of unit RTCS unit:
  • Unit of RTCS-01, intended for start and control of main aggregates (motors, etc) and test of voltage occurrence on single-phase and three-phase current mains with 380V by the given DTMF code;
  • unit of RTCS-02, intended for DTMF control command transmission to RTCS-01 unit and reception from its information about unit situation.
RTCS-01 and RTCS-02 units give the opportunity to build remote control systems with large number of various electric machines and carry out control of units’ situation on various areas.
Each of  RTCS-01 and RTCS-02 unit operates in a complex with radio station. The radio station can be any type with the opportunity to voice frequency transmission.
