1.1 What Instrument Do I Have?

Thank you for choosing this Controller.

 

It provides precise control of industrial processes and is available in three standard DIN sizes:-

 

• 1/16 DIN Model Series 816

• 1/8 DIN Model Series 808

• 1/4 DIN Model Series 804

 

Seven model variants are available. A summary of the functionality of each model is shown in the following table:-

A universal input accepts various thermocouples, RTDs or process inputs. Up to three (816) or four (808 and 804) outputs can be configured for control, alarm or re-transmission purposes. Digital communications and a current transformer input are available options in all models.

 

A label fitted to the right side of the sleeve shows the instrument part number, serial number and customer reference.

 

A label on the left side shows the terminal connections, and a brief specification of the terminal functions for the hardware fitted.

 

The figures show examples of these labels.

 

 

A full configuration mode may also be entered which allows controllers to be customised to specific requirements.

 

This Manual explains installation, wiring, configuration and use of the controllers.
