About This Product

Active barrier with a power supply function that can safely separate the current signal circuit of 4 to 20 mA

■ Applications
The active barrier RN221N supplies power to the converter (also supports dangerous places) and transmits an insulated signal. In addition, converter monitoring by HART® diagnostic function is also possible as an option. In the event of an error, the RN221N sends an alarm. This makes it easy to identify a temporary error location.

・ Insulation 4-20mA current circuit
・ Loop power supply supply
・ Supplies power to a 2 -wire converter
・ Monitoring smart converters by early warning system
・ Essential safety sensor power supply for dangerous places

■ Advantages
・ Flexible support for a wide range of power supply
・ Compact DIN rail housing
・ International explosion -proof certification, ship class certification
・ Compatible with two directions HART®. With a communication socket for HART® sensor set -up. The status information of the converted converter is evaluated by the Hart® protocol.
・ Automatically select the operation mode of the primary or secondary massa
・ Monitoring sensors by early warning system
・ Manual or automatic reset of relay contact
