Real DCS functionality

Foxboro Automation, a unit of Invensys Process Systems, 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. The T2550 controller is said to be 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. www.foxboro.com
