Sourcing & lifecycle
Approvals include CE, cULus, Lloyd, and NK, covering industrial control and marine applications. Documentation for compliance audits is available upon request via RFQ.
Mounting & expansion
Mounts on a backplane; CPU occupies one slot. Expansion reaches 80 modules across 7 racks via backplane interfaces. The RS-232C port is typically used for programming or Modbus communication; the USB port provides a direct connection to CX-One software. Both ports are active simultaneously; no port-switching DIPs.
