Most Configurations Are In Stock For Same Day Shipment
We will advise immediately if your order will be delayed

The ISE/West 4400 is a powerful Programmer, packed with innovative features to control complex processes. Metal treatment and environmental chambers are typical applications. The 4400 is suitable for controlling multiple slave controllers via comms, for multi-zone processes. It's unique modular construction allows the addition of low cost options at any time. It's simplistic operator interface is preferred by most operators.

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