Πληροφορίες για το προϊόν "RPS-4M 4-Slot Redundant Power Communication Module, Modbus RTU/TCP"
RPS-4M CR is a 4-slot redundant power communication module that combines N+1 power backup with remote monitoring of the power modules it hosts. Each slot takes a 100W power module, and when four modules are fitted the unit can deliver the rated power of three, so the failure of any one module does not interrupt supply. The load current is shared evenly across the modules, which avoids premature wear on a single unit.
Power modules can be hot-swapped, so a faulty unit can be replaced without shutting down the system. The built-in diagnostics report the temperature, output current, status and usage time of each module, and a relay alarm output signals a module failure to external equipment. Diagnostic data can be read by a supervisory system over RS-485 or Ethernet.
Communication uses Modbus RTU slave on the RS-485 port and Modbus TCP server with a built-in web server on the 10/100Base-TX Ethernet port. Engineers can use the module in ICP DAS redundant architectures covering I/O, controller, Ethernet ring and HMI redundancy.
Applications
- Redundant power supply for I/O data acquisition systems
- Controller redundancy for program control
- Ethernet ring communication redundancy
- HMI redundancy for display and information recording
- Remote monitoring of power module condition in industrial control cabinets
