The ANTARES 8DO-SCL Remote I/O Module (single channel limitation) is operated and supplied with power by the Rail Control Unit (RCU) ANTARES. This module is suitable for the direct control of up to 8 intrinsically safe solenoid valves in the explosion hazardous area. 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 the module to be programmed and the output load to be calculated automatically. See the system description for installation instructions.
