SMC EX120/121/122 SI Unit for Valve Manifolds (16 Outputs)

SMC EX120/121/122 SI Unit for Valve Manifolds (16 Outputs)

SMC EX120/121/122 series compact serial interface (SI) unit that drives up to 16 solenoid valve outputs on a manifold over DeviceNet, CC-Link or CompoNet.

Key features

  • Compact output-only SI unit with up to 16 solenoid outputs
  • EX120 plug-in type for SV1000-4000, VQ1000/2000 and SY3000/5000/7000 manifolds; EX121 flat-cable and EX122 plug-in DIN-rail types for SY3000/5000
  • Protocols: DeviceNet (16/16 or 0/16 occupied points), CC-Link Ver.1.10 and CompoNet in NPN or PNP output
  • Communication and power connectors supplied with DeviceNet types; CompoNet types include power connector EX9-CP2
  • DN1-X26 has no manifold part number set; DeviceNet PNP and S-LINK V versions available made to order
  • Communication connectors EX9-CCM1/CCM2 and T-branch power connector EX9-CP3 available as accessories
