The ISE/West 4700+provides a programmable safety cut out with optional outputs for annunciators and alarms. A latched relay cuts power to the process if it exceeds the safe value. The unit must be reset before the process can continue.

Plug in direct replacement for the N4700 / N4701 series.

We fully configure the control prior to shipment so that it is truly plug & play. Configurations can be easily modified if your requirements change.
