. | 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. |
