West 4100+ Digital Temperature Controller

The West 4100+ is part of the Plus Series of controllers that take flexibility and ease of use to new levels.

The 4100+ controller is an evolved product from the N4100. The product benefits from having more versatile features and user-friendly functionalities such as remote setpoint inputs, digital inputs, plug-in output modules, a customisable operator/HMI menu, jumperless and auto-hardware configuration, and 24VDC transmitter power supply.

It has been designed to incorporate improvements, save users’ time (as much as 50% on product set-up), reduce inventory stock and virtually eliminate the likelihood of operator errors.

The 4100+ provides a product which surpasses competitive offerings in terms of ease of use, delivery and value for money.
