Affordable, Well-Featured, Easy to Use and Adaptable
APPLICATIONS:
Fail-safe protection device to prevent damage to equipment or products. It will shut down a process when a preset temperature is reached and cannot be reset by the operator until the process has returned to a safe condition.
INDUSTRIES
Industrial and lab ovens/furnaces
Plastics and thermal forming
Packaging applications
And any other where protection against out-of-range
temperature condition is a critical requirement

DESCRIPTION
The West 8700+ is part of a range of new generation '+' Series limit devices that share the same distinctive styling as the '+' Series temperature controllers.
The expanded '+' Series limit controller platform includes 1/4, 1/8 and 1/16 DIN models that incorporate numerous product specification, communication, display interface and software improvements that surpass competitive limit device offerings in ease of use, delivery and value­per dollar characteristic of the growing '+' Series product family.
By adding more versatile features and user-friendly functionality like digital inputs, an easy-to-use HMI, jumperless and auto-hardware configuration, 24VDC transmitter power supply and MODBUS communication across the range - the new generation West + Series limit controllers transform the complicated into the simple while saving you time (as much as 50% on product set-up), reducing inventory stock and virtually eliminating the likelihood of operator errors.
The + Series limit controllers are affordable, well-featured, easy to use and adaptable with performance features that work for you to make limit control simple.
