Product Description
2.1
General
YT-930 IP converter receives 4~20mA DC signal from the control room and outputs 0.02 ~ 0.1 MPa
signal to pneumatic-pneumatic positioner to operate a control valve system. YT-930 is designed to be
used in Ex ia IIC T5/T6 intrinsic safety or non-explosion proof environment.

Main Features and Functions
➢
Low air consumption level yields to lower plant operating cost.
➢
A wide range of uses with IP66 protection grade.
➢
Can be used at low voltage (8.5 V) and can be compatible with most of general controllers.
➢
Polyester painting makes the product strong against corrosion environment.
➢
Easy dial adjustment for Zero and Span.
➢
Modularized inner parts make maintenance easy and simple.
➢
I/P converter operates normally during sudden changes in supply pressure and / or high vibration
environment.
➢
Air filter regulator <YT-200 series> can be directly installed without any pneumatic piping.
➢
DA and RA can be set for the output pressure relative to the input current signal by simple switch
operation.
➢
DA and RA can be set for the feedback signal relative to the output pressure by simple switch
operation. (Only feedback signal option)
