The RSTi-EP remote I/O system is well-suited for industrial internet-enabled applications. It features an extended operating temperature range, enhanced diagnostics, plug-and-play connectivity, and high channel density – all designed to simplify machine design and maintenance.

  • PROFINET RT, Profibus/Ethernet IP/Modbus TCP-IP, EtherCAT interfaces
  • Hot-swappable with advanced diagnostics
  • Supports PROFINET system redundancy
  • Best in class I/O density
  • Up to 64 I/O modules per node (takes up half the space of traditional systems)
  • High-density analog and digital modules
  • Special-function modules including high-speed counter, frequency, SSI encoder, PWM output, serial communications
  • SIL 3-compliant safety module

RX3i Profinet Scanner

RX3i Profinet Scanner – connect a remote universal RX3i I/O rack of Series 90-30 or RX3i modules to a PROFINET I/O Controller.

  • Profinet RT, Profibus/Ethernet IP/Modbus TCP-IP, EtherCAT Interfaces
  • Direct Fiber Interface directly to the remote I/O Rack
  • Up to 16 Slot racks can be a single node
  • Advanced Sequence of Events recording version available with IRIG-B time synchronization

RX3i CEP Single-Slot RX3i I/O Carrier

The RX3i CEP Carrier, a single-slot RX3i carrier with integrated PROFINET network interface and redundant 24 VDC power supply inputs, is the latest one-slot (expandable to two) expansion module from Emerson. It offers use of existing, advanced RX3i or Series 90-30 I/O in a small footprint, with superior availability for maximum uptime, and maximum flexibility to reduce operating costs.
