Control for electropneumatic valve banks

Camozzi pneumatics has introduced an input module to its series Y electropneumatic valve banks which gives advanced control and sensing. An input module acts like the fingers on a hand (the valve bank being the hand itself). Signals from sensors on cylinders, or any other device, are fed back into the input modules, which then let the circuit controlling the valve bank and the bus system know the exact status of the system at all times.

With the input modules it is now possible to connect feedback signals from the field (end positions of actuators, etc). Using the valve island series Y, it will be possible to connect 48 digital inputs divided in a maximum three modules, in addition to the already known 32 solenoids.

Each module will accommodate eight digital inputs (four x M12, female connectors with five poles). To each connector, two inputs can be connected. The male connectors will be of a DUO type which will allow the connection of two different cables; for example, those of two magnetic proximity switches, CSH. The protection class is IP65.

The initial module and the input modules (of a series Y valve island with fieldbus connection) have a double electrical power supply, one which goes to the electronics (processor) and one which feeds the solenoids. In this way, in case of an emergency stop it is possible to remove all electrical power from the solenoids while still maintaining power supply to the electronics (processor).
