The ISE/West Pro-EC44 is a powerful control with optional programmer and recorder options. The EC44 includes a high contrast dual color backlit display. The display can be programmed to change colors depending on alarm status. It is packed with innovative features to control complex processes without setup complexities found in other controls. The available EC44communication options include USB Port, Ethernet Port, RS485 Port, and Configuration Port. Its simplistic operator interface is preferred by most operators.

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