SMC EX250 series Pneumatic Logic Controller

SMC EX250 Series Pneumatic Logic Controller, 8 Inputs, 8 Outputs - EX250-SAS3

This pneumatic logic controller is a Compact industrial Interface for decentralised valve and I/O control in pneumatic systems. Designed for use with Air as the working medium, it provides local logic and communication connectivity for machine automation. It is intended for environments requiring LED Visual status indication, PNP outputs at 24V and a sealed swivel heavy-series connection with O‑ring for a 45° elbow.

Features & Benefits

• 8 inputs and 8 outputs for local discrete control and diagnostics
  PNP outputs at 24V for direct sourcing of control loads
  LED indicator display for immediate status visibility
  Swivel heavy-series 45° elbow with O‑ring for secure connection
  Operates up to +45°C for typical industrial ambient use
  Compatible with pneumatic media of compressed Air for valve actuation

Applications

• Suitable for decentralised valve manifolds in factory automation
  Ideal for machine I/O expansion where a Compact footprint is required
  used with solenoid valves for sequence control in handling systems
  Suitable for integration into PLC networks via fieldbus gateways
  can be used in control panels requiring clear LED status reporting

What electrical supply and output type does it require?

The unit requires a 24V supply and provides PNP-type outputs for sourcing loads.

How does the module indicate operational status?

A built-in LED indicator provides Visual signalling of run, error and power conditions.

What medium and environmental limit should be observed?

The controller is for use with Air as the medium and is rated for operation up to +45°C.

What connection style is used for pneumatic supply entries?

It uses a swivel heavy-series connection employing an O‑ring and a 45° elbow for sealed fittings.

How small is the controller for tight installations?

The design has a Compact footprint suitable for installations around 63 x 75 mm.
