Omron E5ZN-DRT DATASHEET

DeviceNet Communications Unit

E5ZN-DRT

Connect the E5ZN Modular Temperature
Controller to DeviceNet

• The I/O link function allows setting and monitoring (e.g., of
present values) for the E5ZN Modular Temperature Controller to
be performed without communications programming.

• Up to 16 E5ZN Modular Temperature Controllers can be con­nected to one Unit.

• All the parameters for the E5ZN can be uploaded or download­ed in one operation using DeviceNet Configurator.

Note: A DeviceNet Communications Unit and Terminal Unit are required to connect to DeviceNet. (For details on the Terminal Unit, refer to

page 148 or to the E5ZN Catalog (H116-E1-02).) Two End Plates are provided with E5ZN-SCT24S Terminal Units. When mounting to a DIN
track, be sure to mount End Plates on both sides.
