SMC’s EX250 series is designed to connect the valve
series VQC, SV and SY (see chapter 4) and input mod-
ules for different eldbus protocols.
All input and output signals are combined in a
compact manifold that conforms to IP67. Up to 8 input
channels and 8 outputs can be connected in a single
manifold.
All connections (air, power supplies, eldbus and
sensor) are located on the same side of the manifold
which allows mounting in tight spaces.
All status indicators clearly visualized by LEDs on the
front of the manifold.
Installation manuals are available on SMC’s website
www.smc.eu.
For eldbus connectors and cabling,
see end of this chapter.
