SMC EX250-SDN1-X122 Inline Pneumatic Manifold

The SMC EX250-SDN1-X122 Inline Pneumatic Manifold is a compact nine‑station valve manifold with an attached EX250 SI Unit, configured in a VQC4-0011‑BBBZ arrangement to deliver integrated pneumatic control in a single package. As part of the EX250-SDN1 family, it provides 32 inputs and 32 outputs over a DeviceNet interface, enabling 24 VDC valve coils and I/O expansion in a space‑saving footprint. The assembly is IP67 rated for rugged environments, operates from 24 VDC, and is suited for an ambient range of 5 to 45 °C with 35–85% relative humidity. DeviceNet communications support up to 500 kbps (with common options at 125/250 kbps), and outputs are Source/PNP with a negative common; the unit includes surge suppression for coil protection. Weight is around 250 g, and the package can include two tie‑rod accessories to aid mounting rigidity.
