Loop powered isolators PR3185 and PR3186 are economical but high performance devices in an exceptional package These are available in one and two channel models for absolutely exceptional packing density on a rail. Response time is less than 5ms and accuracy [conformity] is better than 0.1%. These can be mounted in Zone 2 and certified to IECEx – they are not isolation barriers.

• Powered on input 3185A or output 3186A 24VDC +/-30%
• Voltage drop 1.2V on 3185 and 2.5V on 3186
• Isolation 2500VAC
• Loop supply on 3186 series 17V DC at 20mA
