Note 1) Refer to “Applicable Fluids List” on page 17.
Note 2)
When fluids with high temperature are used, the available pressure range will be reduced. (For details, refer to “Operating Pressure Range” on page 4.)
Note 3) The response time until the set value reaches 63% in relation to the step input.
Note 4) When options are used, add the weight of the optional parts.
Note 5) Piping port and the metal part of the body are grounded to DC(–)/blue line. Power supply with positive ground cannot be used. Please consult SMC
if the product is used for positive ground environment.
