Output

Output to actuator . . . . . . . . 0 ... 100 % supply air pressure

Supply

Supply air pressure . . . . . . . 1.4 ... 6 bar (20 ... 90 psig)
Air supply. . . . . . . . . . . . . . . according to ISO 8573-1

according to IEC 654-1. . . . . The device can be operated
at a class D2 location
Transport and
storage temperature. . . . . . . –50 ... 80°C (–58 ... 176°F)
Storage conditions
acc. to IEC 60 721-3-1 . . . . 1K5, 1B1, 1C2, 1S3, 1M2
Protection class . . . . . . . . . . IP 54; IP65 as an option
IP65 protection class can be selected from model code
option –F or can be retrofit on existing device by ordering
the kit EW 411 406 301.
