Digital Temperature Controllers

E5CN/E5CN-U

Improvements to E5CN Functionality

■ Changes

Model numbers have been changed to allow for multi-input

specifications.

Precautions in Replacing Previous

Controllers

• The input type setting numbers have changed to allow for multi-

input specifications. (The default setting is for a K sensor between

-200 and 1,300°C.)

• Previous E5CN Controllers cannot be removed from the case for

replacement with new models. Replace the case at the same time.

• The previous ThermoTools cannot be used with the new Controller

models. Use the ThermoTools scheduled for marketing from July

2004.

• The height of the front panel that extends when the Controller is

mounted to a panel has been reduced from 9 to 6 mm.

Note: Items That Have Not Been Changed

• Panel cutout dimensions

• Panel interior dimensions for panel mounting

• Wiring terminal sizes

• Wiring terminal arrangement

• Parameter setting procedure

■ Improved Functions

The previous and new models can be easily differentiated by looking at the front panel. The OMRON logo is in a different position.

Basically, the Controllers are upwardly compatible. The terminal arrangement, terminal sizes, and depth for panel mounting have not been

changed. Changes are listed in the following tables. For details, refer to the E5CN/E5CN-U Temperature Controller User's Manual (Cat. No. H129)

and to the E5CN Temperature Controller Communications User's Manual (Cat. No. H130).
