1) Brief Introcucion

  LU-B11 (type F) Barriers (analogue output, 1 channel) conform to the standard of GB3836.1-2000 and GB3836.4-2000,and [Exib] IIC for explosion-proof certified. The barriers may isolate the 4-20mA d.c. control signal which from the regulator or mainipulator and then output to elctrical converter or electrical valve positioner on industrial control field, and at the same time the barriers prevent the hazardous energy from intrinsic safety terminal into hazardous area(industrial control field), to insure the system intrinsic-safety explosion-proof.
