Steam Turbine Controllers

The new line of steam turbine controllers, TRI SEN 3410/3420, is designed to provide an upgrade path to triple modular redundancy (TMR) capability for both existing TS410 installations and new applications. The 3410 controller operates as a plug-and-play replacement for the TS410 and TS410A systems, while the 3420 controller serves new applications. The TMR systems use three isolated, parallel control systems with extensive diagnostics and 2-out-of-3 voting to help ensure safety and availability.

In facilities with existing TS410 systems, the manufacturer uploads the new application to a program that translates it into TriStation 1131 programs, and it leaves the field wiring in place, making the upgrade easy. A replacement transition panel fits into the same space as the existing TS410 panel, and the chassis can be installed up to 100 ft. from the transition panel. With the manufacturer's overall TRI-SEN line of turbomachinery controls, users get solutions that range from economical, configurable digital governors to fully integrated TMR systems. The line includes full solutions for start up, sequencing, speed, machinery protection and operator interface.
