The T2550 controller is the first in the vendor’s low-cost Foxboro A2 distributed control system line to bundle full process control and I/O functionality in a compact, field-mountable baseplate and termination assembly.
Like a PLC, it can be deployed independently or as part of a centrally controlled network. Each unit can have up to two process controllers, which can operate in a simplex mode or in an optional redundant mode. 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. The T2550 controller allows low-cost, multi-loop process control capability to be deployed right at the process unit, says Betty Naylor-McDevitt, marketing director at the vendor. “While the T2550 can be easily integrated into a control or plant network, it will continue to control the process even if the network link is lost.”
