The West 6700+ limit controller is a member of the P series family. The instrument provides a latched relay output activated when the process value either exceeds or falls below the pre-set limit level, providing a fail-safe cut-off that has to be reset before the process can continue. The LED indication shows when limits have been exceeded and when the relay is latched out.
The 6700+ provides a valuable control ‘watchdog’ for most systems with a full range of universal sensor input options.
