Ordering Information
Order Control Output Boards and Option Boards separately below. Example: for a Relay Control Output, order the E53-R4R4 Output
Board in addition to the E5CK-AA1-500 Process Controller. For E5AK or E5EK, order an E53-R output module.
Note: You can mount only one Output Board and one Option Board to E5EK or E5CK.
Item
Standard models
Position--proportional
24 AC/DC models
Note: 1. When using the heater burnout alarm function with a standard model, the Linear Output Module cannot be used for the control
outputs (heat). 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.
2. Order Output and Option Boards separately.
3. E5EK-PRR2/E5AK-PRR2 controllers are supplied with relay output. The relay output is not compatible with any other module.
