Key Features:

  • 3+1 Level Structure: MM10 module; SCU module; RCU module; BMU module.
  • Online Program Upgrade: Support direct connection of USB flash disk to SCU module to upgrade ; Support EMS upgrade through SCU module via host computer.
  • Support Bidirectional IO Ports to Achieve Automatic Address Coding: The BMU module supports 2-way bidirectional l0 ports to send/receive instructions, all BMUs in a single cluster can be automatically encoded and the lO ports can support bidirectional blind insertion.
  • Multi-ports Environment Supervision Devices Data Access: SCU modules support 3-channel isolated CAN communication, 3-channel LANcommunication,3-channel RS485 communication,1-channel RS232 communication Ports are reserved for to fully meet the access of other devices in the entire ESS.
