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 con- nected to one Unit. All the parameters for the E5ZN can be uploaded or download- ed in one operation using DeviceNet Configurator. Ordering Information List of Models Name External input power Applicable Temperature Model supply voltage Controller DeviceNet 24 VDC E5ZN E5ZN-DRT Communications Unit 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.
