The EX250 integrated assembly comprises a digital serial interface and a user-defined number of solenoid control valves mounted on a manifold. It reduces valve wiring ensuring easier, faster connection in confined spaces.

The unit can drive 32 solenoid valve outputs and has 32 electrically stackable sensor inputs. SMC claims the unit is suitable for use in industries as widespread as automotive assembly, food and beverage manufacturing, water treatment, packaging, electronics and chemical processing, delivering increased productivity and efficiency when used with DeviceNet or Profibus-DP network systems.

Piping and electrical connections are aligned on one side of the unit to minimise space requirements. Valve ports are all fitted with replaceable push-in piping connectors for ease of maintenance.

The EX250 is IP67 rated and is fitted with self-diagnostic functions including solenoid valve voltage monitoring and sensor power supply over-current cut-off.

Each valve incorporates an LED on/off status indicator, surge protection to prevent back-EMF and a flush-mounted manual override facility for testing pneumatic circuit functions.
