Product design
Active barrier, 1-channel
• The active barrier is used for the transmission and galvanic isolation of 0/4 to 20 mA/
HART signals. The device has an active/passive current input to which a 2- or 4-wire
transmitter can be directly connected. The output of the device can be operated actively
or passively. The current signal is then available to the PLC / controller or to other
instrumentation at plug-in screw terminals or optional push-in terminals.
• HART communication signals are transmitted bidirectionally by the device. Connection
sockets for connecting HART communicators are integrated into the front of the device.
• The device is optionally available as an "associated apparatus", which allows devices to be
connected in Ex Zone 0/20 [ia] and operated in Ex Zone 2 [ec]. 2-wire transmitters are
supplied with power, and transmit analog 0/4 to 20 mA/HART measured values from
the hazardous area to the non-hazardous area. These devices are accompanied by
separate Ex documentation, which is an integral part of this manual. Compliance with
the installation instructions and connection data in this documentation is mandatory!
