Endress+Hauser 2 Channel Galvanic Barrier, Isolating Amplifier, NAMUR Sensor, Switch Input, Relay Output, SIL 2, Zone 2

The Endress+Hauser two-channel NAMUR isolating amplifier is designed for the safe operation of proximity switches according to EN 60947-5-6 (NAMUR) as well as open and mechanical contacts with resistive coupling elements. With a universal power supply (24 to 230 V AC/DC) and one relay output (changeover) per channel, this device is ideal for intrinsically safe (Ex i) circuits up to zone 0 (gas) and zone 20 (dust) in the Ex area.
