Signalling / protecting modules type M...

Technical info

Modules type M... are parallely connected with relay coil. Polarity P: -A1/+A2. Polarity N: +A1/-A2.

Modules type M : 

  • Module D (polarization P)- it limits overvoltage on DC coils;
  • Module D (polarization N) - it limits overvoltage on DC coils;
  • Module LD (polarization P) - it limits overvoltage on DC coils. Coil energizing indication;
  • Module LD (polarization N) - it limits overvoltage on DC coils. Coil energizing indication; 
  • Module RC - it protects against EMC disturbance. It limits overvoltage;
  • Module L - coil energizing indication;
  • Module LV - it limits overvoltage on AC and DC coils. Coil energizing indication;
  • Module V - it limits overvoltage on AC coils. No indication;
  • Module R - it limits harmful voltage on AC coils induced in long lines which causes unwanted making of the relay.
