Camozzi pneumatics has had the series Y electro-pneumatic valve banks on the market for a few years.

Now Camozzi pneumatics has released input modules to give the Y series valves advanced control and sensing, which are available from Griffiths Components.

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 your system at all times.

With these new input modules it is now possible to connect feedback signals from the field, (end positions of actuators etc.) This input module will be available from autumn.

Using Camozzi pneumatics valve island series Y, it will be possible to connect 48 digital inputs divided in max. 3 modules, in addition to the already known 32 solenoids.

Each module will accommodate 8 digital inputs (4 x M12, female connectors with 5 poles). To each connector, 2 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 mod. 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).

A typical input module is fed off the internal bus only would be obscured in the case of an emergency stop if no additional power supply existed and as a result, the electrical signals from the sensors to the control unit (PLC) would be interrupted and it would not be possible to read the actual positions of the actuators during the emergency stop.
