Description

Elemer-BRIZ series spark protection barriers are designed for installation in control cabinets. The devices provide explosion protection of [Ex ia Ga] IIC and 2Ex nA [ia Ga] IIC T4 Gc X type and successfully replace imported analogues in control systems of oil and gas transport facilities, storage facilities, chemical industry, oil and gas refineries and other enterprises where instrumentation is operated in hazardous areas.

ELEMER-BRIZ NAM-Ex barriers are designed for transmission of discrete signals of NAMUR standard sensors or relays to a safe area. They provide intrinsic protection of input circuits and form the power supply of sensors on each channel.
