Upgrade Benefits

  • Replaces obsolete 90-70 controller, extending service life.
  • Boosts overall performance of automation systems.
  • High speed processor and patented technology allows faster throughput without information bottlenecks.
  • Allows easy integration of new technology into base system. System integration over multiple platforms allows higher performance and increased controller flexibility.
  • Expanded I/0 offering with extended features for faster processing, advanced diagnostics, and a variety of configurable interrupts.
  • Control has personal storage and can store machine documentation (Word, Excel, PDF, CAD, & others), to improve troubleshooting and reduce downtime.
  • Increase Uptime
  • Enhance Operational Flexibility
  • Improve Maintainability

How it works

GE IP 90-70 Sequencers are currently nearing the end of their life cycle and will soon become legacy units.

PACSystems* RX3i controller is an incredibly powerful Programmable Automation Controller (PAC) able to replace the GE IP 90-70 Sequencer.

Features a single control engine and a universal programming environment.

The PACSystems RX3i features:

  • High speed, PCI- based backplane for fast through put of new advanced I/O or serial backplane for easy migration of existing Series 90-30 I/O.
  • Existing VersaMAX I/O can be reused and modified for Rx3i compatibility.
  • Open communications support including Ethernet, GENIUS, Profibus, HART, DeviceNet, and serial.
  • Supports high density discrete I/0, universal analog, isolated analog, high density analog, high speed counter, and motion modules.
  • Integration of control platform, logic, motion, HMI, and high availability
