The ANTARES 4AIO Remote I/O Module is operated and supplied with power by means of the Rail Control Unit (RCU) ANTARES. This module allows the direct linking of 4 intrinsically safe transmitters with 2, 3 or 4 conductors or the output of 0 to 20 mA or 4 to 20 mA signals. The hot-swap capability allows the electronic unit to be replaced without disconnecting from voltage even in an explosive atmosphere. The internal and galvanically isolated bus connection is established by simply plugging the modules to the RCU. A bus rail is not necessary. Open circuit/short circuit monitoring can be programmed for each channel. The bus status messages and individual messages per channel are displayed by the LEDs. This also enables diagnostics on the module. The Software ANTARES Designer allows parameters to be set for the signal range, channel type (in or out) and a 4-stage input filter for each channel. See the system description for installation instructions.
