SMC EX250 series Pneumatic Logic Controller

SMC EX250 Series Pneumatic Logic Controller, 48 Inputs, 32 Outputs - EX250-SEN1

This pneumatic logic controller is a Compact industrial module designed to manage pneumatic valve networks and sensor inputs within automation systems. It operates from a 24V supply and accepts Air as the controlled medium. The unit provides LED indication for status monitoring and connects via a swivel heavy-series 45° elbow connector to simplify cabling in confined assemblies. It is intended for use where reliable PNP switching and a dense I/O count are required in factory and process environments.

Features & Benefits

• 48 inputs and 32 outputs deliver high I/O density for complex control
  PNP output configuration enables sink to source integration with PLCs
  24V supply reduces integration complexity with standard control systems
  LED indicators offer immediate Visual status for diagnostics
  Operating range to +45°C permits use near warm equipment
  Swivel heavy-series 45° elbow eases tight-cabinet wiring routes

Applications

• Suitable for distributed valve manifold control in automated lines
  Ideal for pneumatic sequencing in packaging machinery
  used with solenoid valves in material-handling installations
  Can be used for remote I/O extension on manufacturing cells
  Suitable for factory-floor automation requiring Compact controllers

How is the unit connected to plant networks and field devices?

Connection is MADE using a swivel heavy-series 45° elbow Interface for the supply and signal cabling, and I/O devices wire directly to the designated terminals
the controller expects a 24V supply for logic and outputs.

What environmental limits must be observed during installation?

The controller is specified to operate up to +45°C and within non‑condensing humidity ranges
avoid locations exceeding that temperature to maintain correct operation.

What output behaviour occurs on communication failure?

Outputs are PNP type
in the event of communication irregularities the controller’s built-in status LEDs indicate errors so operators can identify and isolate the fault for corrective action.

Which medium is this device intended to control?

The controller is designed for pneumatic systems and specifically manages devices using compressed Air as the controlled medium.
