Ordering Information

■ List of Models

Note: 1. When using the heater burnout alarm function with a standard model, the Linear Output Unit cannot be used for the control outputs (heat).

2. Be sure to specify the Current Transformer, Output Unit, and Option Unit when ordering.

3. The Digital Controller provides transfer outputs at 4 to 20 mA for the PV and other values and control outputs at 4 to 20 mA for the current

outputs.

Note: The Digital Controller uses a dedicated, high-resolution Output Unit. The E53-C Current Output Unit for the E5

@X cannot be used with the

Digital Controller.

Note: 1. The Option Unit can be used either by the E5AK or E5EK.

2. The E5AK allows a maximum of three Option Units to be mounted. Refer to page 8 for mounting combinations.

The E5EK allows only one Option Unit to be mounted.
