Description

The Remote I/O-Module ANTARES 8AI is operated and supplied with power by means of the Rail Control Unit (RCU) ANTARES. This module is suitable for the direct connection of 8 intrinsically safe two-conductor transmitters.

The hot-swap capability allows the electronic unit to be replaced without disconnecting from voltage even in an Ex atmosphere. The internal and galvanically isolated bus connection is established by simply joining the modules to the RCU. A bus rail is not necessary. Line break/short-circuit monitoring can be programmed for each channel. The bus status messages and individual messages per channel are displayed through the LEDs. This facilitates diagnosis at the module as well. The ANTARES Designer software allows parameters to be set for the signal range and a 4- stage input filter for each channel. See the system description for installation instructions.
