Controllers and I/O

Boost system productivity with powerful controllers & I/O. The I/A Series® Control & I/O sub-system combines seamless, fully integrated control with a powerful set of tools to optimize your plants productivity & performance.

The latest generation of I/A Series controllers can co-exist with and migrate from the earliest generations of I/A Series hardware. The CP270s provide twice the capacity and three times the performance of older controllers - improving cost effectiveness in demanding applications. The CP270s are optionally fault-tolerant & perform regulatory, logic, timing & sequential control, as well as data acquisition, alarm detection & notification.

Patented fault-tolerance Providing the highest availability of any system in the process industry, I/A Series hardware is engineered for non-stop operation. Fault-tolerance resides at all levels of the system, from process controllers to redundant field networks & fieldbus modules. With innovative industrial packaging & rugged environmental protection, with optional intrinsically safe capabilities, our Control & I/O solution promises unsurpassed reliability for your process. I/A Series controllers and I/O products are designed to run in G3 environments on the plant floor with up to a 60º C ambient temperature. Use of fiber cabling in the controller virtually eliminates noise and grounding problems in the system.

Remote I/O Solution. Designed for highly distributed applications, our I/O locations are best suited to the application -- in the control room or the process units. Our innovative compact packaging reduces the physical space required in the control room and when distributed to the field dramatically reduces the cost of field wiring

Foxboro Automation introduces distributed control system

Foxboro Automation has extended its low-cost Foxboro A2 distributed control system (DCS) with a compact new product that combines control and I/O technology into an expandable baseplate or chassis. Like a PLC, this can be deployed independently or as part of a centrally controlled network.

“In addition to our flagship I/A Series automation system, Invensys offers the Foxboro A2 system as a highly cost-effective alternative for smaller applications. The new Foxboro A2 T2550 controller now allows this low-cost, multi-loop process control capability to be deployed right at a process unit,” said Betty Naylor-McDevitt, marketing director of the Foxboro Automation unit of Invensys Process Systems. “While the T2550 can be easily integrated into a control or plant network, it will continue to control the process even if a network link is lost. Combined with optional controller redundancy, this provides a high degree of fault-tolerance at a very low cost.”

The T2550 controller is the first product in the Foxboro A2 line to bundle full process control and I/O functionality in a compact, field-mountable baseplate and termination assembly. Each unit can have up to two process controllers, which can operate in a simplex mode or in an optional redundant mode. No additional engineering is required to make the system redundant. The standard T2550 control and I/O baseplate can also house up to 16 I/O cards. These can be replaced live, under power, without disturbing field wiring or other I/O.

Like other members of the Foxboro A2 product family, the T2550 controller supports high-density packaging of a broad range of analog and digital I/O types. System controllers can be mixed and matched as needed to meet specific control and price requirements using the highly flexible licensing strategy. Users pay only for currently needed functionality and can upgrade at any time without cost penalty. Redundant processors with automatic switchover, redundant power supplies, and redundant network connections can be specified on a controller-by-controller basis. Control strategies are configured graphically using IEC-61131 tools including function block, sequential function charts, structured text, and PID and advanced regulatory control. A library of pre-constructed function blocks is also available to speed application development.
