SMC EX250 series Pneumatic Logic Controller

SMC EX250 Series Pneumatic Logic Controller, 32 Inputs, 32 Outputs - EX250-SDN1

This pneumatic logic controller provides decentralised, field-bus ready I/O control for air-based automation systems. Designed for panel or DIN-rail mounting, it links sensors and valve manifolds to common industrial networks while displaying status via an LED indicator. The unit operates from a 24V supply and suits applications requiring compact, high-density control of pneumatic outputs in ambient temperatures up to +45°C.

Features & Benefits

• 32 inputs and 32 outputs for high-density I/O control
  PNP outputs to simplify interfacing with sourcing devices
  Swivel heavy-series O-ring 45° elbow for secure connections
  LED indicator for clear real-time status feedback
  Separate common power supply option to isolate valve loads
  Compatible with Air as the controlled medium for valve actuation

Applications

• Suitable for distributed valve manifold control in factory automation
  Ideal for PLC integration over DeviceNet and other field buses
  Used with VQ/SV manifolds to drive solenoid valves on demand
  Can be used for machine I/O consolidation where DIN-rail mounting is required

What operating temperature range can I expect in typical use?

The controller is specified to operate up to +45°C and is intended for normal industrial ambient conditions without condensation.

How does the unit handle network and valve power connections?

It accepts a 24V control supply and includes separate power supply connector options to allow independent powering of valve loads and control electronics.

Are there protections for vibration and electrical isolation?

The design meets industrial vibration and impact resistance norms and provides insulation between external terminals and chassis as specified for industrial I/O modules.

What connector types and mounting are supported?

The unit uses M12-style connectors for communication and power, supports DIN-rail mounting, and offers swivel heavy-series elbow fittings for pneumatic ports.
