The Supply and Communication Interface Box (SCB) is an I/O Unit for the Supply and Communication Computer (SCC). It controls relays that can be connected to for example alarm devices. The SCB is equipped with one or two independent electronic boards. This enables a configuration with a second independent measuring channel in the same cabinet. This type of configuration can be used for independent High Level or Overfill Alarm units Each electronic board has eight relay control outputs, a power supply and a system failure watchdog/relay control circuit. If the communication with the SCC is interrupted, the watchdog will activate the System Failure Alarm. The first relay is used as System Failure Alarm output, the remaining relays are for general purpose alarm and control.
