Amikon offer diverse GE items

The versatility of the 90-30 series is due to its large variety of CPUs, and each of the 11 available CPUs can accept multiple expansion modules for additional features. These CPUs range from standard entry level CPUs, mid-range models and high-end performers.

CPUs

Standard Models include the CPU 311, CPU 313 and the CPU 323. The 311 and 313 offer 160 discrete I/O and 5 I/O module slots, while the 323 allows up to 320 discrete I/O and 10 expansion I/O slots. All three models offer 64 In/32 Out analog capability.

These standard models have the CPU built into the backplane, making all onboard slots capable of accepting I/O. They also accept EtherNet and various bus protocol modules and use Ladder Logic and SFC for their programming language. While the 311 only has 6K bytes of memory, the 313 and 323 each have 12. All three standard models have a single serial port.

Midrange models consist of the CPU331 and the CPU341. They offer increased functionality over the entry level models that include features such as override capability, and a real time clock with battery backup. Both he 331 and 341 offer 1024 discrete I/O, a considerable jump compared the entry models.

Both mid-range models offer 49 I/O expansion slots and a single serial port. But the biggest jump between these two models is in the analog capability. The 331 allows 128 In/64 Out while the 341 jumps to a high of 1024 In/256 Out.

Coming in on the high end are the CPU350, CPU351, CPU352, CPU360, CPU363 and CPU 364. These high-performance CPUs achieve much higher throughput by using an Intel 386EX processor. They can handle a much higher level of I/O and can use either Ladder Logic, SFC or “C”.

All high-end models allow 4096 discrete I/Os and all have analog capability of 2048 In/512Out. All high-end models have 80K bytes of user logic memory except for the 364 which has 246K. The same is true for the number of serial ports with each model having 3, again the exception being the 364 which has 1 RS485 port, 1 EtherNet port and 1 TCP/IP port built in.

The 90-30 series CPUs are capable of being accessed over the internet can be attached to an EtherNet LAN and they were designed to operate with a variety of third-party devices as well as HMIs and motion controls. All models have:

PID functionality to control temperature, flow, pressure and other process related factors

Four level password security to protect the physical, logic and application security

Complete diagnostics for both the CPU and I/Os

Capability to change programming online

RX3i PAC System General Specifications and Features

With many controllers, changing them out at end of life out requires a complicated migration that often includes new software, new firmware, and other integration differences. They may also include mechanical issues like mounting options, incompatibility with existing enclosures and other headaches. But while the RX3i was designed to add functionality and capacity compared to the 90-30 series, it does so without disrupting the existing system and can be done incrementally and on the fly to prevent shutdown.
