223) Seek a time relay circulation circuit diagram, can control a electromagnetic valve changing-over? 224) An alteration scheme based on FX2N PLC is proposed for the relay control system of DU modular machine. 225) The serial links are point - to - point Frame Relay and need an IP addres...
If both input circuits are closed, the DI safety relay checks the status of the safety valve. If one or both solenoids of the safety valve are energized, the Status contact is open, and the DI safety relay does not energize its outputs. If both solenoids are de-energized, the Status ...
