West 4700+ Limit Controller
- The 4700+ limit controller is a member of the P series family. The instrument provides a latched relay output which is activated when process value either exceeds or falls below the a pre-set limit level, providing a fail-safe cut off which has to then be reset before the process can continue. The LED indication shows when limits have been exceeded and when the relay is latched out.
- With a full range of universal sensor input options the 4700+ provides a valuable control 'watchdog' for most systems.
