LU series safety barriers/isolators/power suppliers

LU-A/B/AB series Barriers: conform to the standard of GB3836.1-2000 and GB3836.4-2000, and [Exia]ⅡC for Explosion-Proof certified.

LU-A safety barriers (analogue input): provide isolated DC voltage from safe-area to hazardous-area for 2-wire transmitters, and transform 4-20mADC which from the 2-wire transmitter to isolated 4-20mA.d.c. to output.

LU-B safety barriers (analogue output): may isolate the 4-20mAd.c. control signal which from the regulator or manipulator and then output to electrical 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.

LU-AK safety barriers (digital input): receive switch/proximity switch input which from hazardous-area, and transfer it to standard electric level signal to output to safe-area after isolated.

LU-BK safety barriers (digital output): through the node switch or logic level signal to control the power signal which from the safe-area, and then output to drive the intrinsic-safe device which in the hazardous-area.

LU-G series isolators/power suppliers: are used to each kind of signal input circuits such as the 2-wire transmitter input, voltage /current input, THC input, RTD input and slide-wire resistance input. The isolators/power suppliers would transform the above signals to isolated standard process signals and then output to control systems or intelligent instruments.
