Product description:

Direct connection of PROFIBUS DP to pneumatic valve manifolds

This SI Unit represents a PROFIBUS DP slave for SMC pneumatic valves. It is designed for digital and analogue data control by connecting compatible EX245


modules and for use within rugged industrial environments, especially automotive plants.

Main Features

  1. IP65 protection
  2. Special M23 (17 pins) connector for robotic applications (PROFIBUS DP and power supply)
  3. Up to 32 digital outputs for manifold type solenoid valves
  4. Up to 128 digital inputs
  5. Up to 64 digital outputs independent of solenoid valves
  6. Up to 8 modules (limited by the total current consumption)
  7. Protection function for short circuit and integrated diagnostics for short circuit and dropped power supply
  8. Galvanically isolated power supplies (PROFIBUS DP, logic / sensors, valves / loads and additional supply for loads)
  9. Modular station (free module configuration)
  10. Flexible power supply combination

Corresponding valve series

  • VQC1000 / 2000 / 4000 series
  • SV1000 / 2000 / 3000 series
  • VSR8-4 / VSS8-4 series
