Allen-Bradley 193-ECM-DNT E300 DeviceNet Communication Module

Allen-Bradley 193-ECM-DNT is a DeviceNet communication module that attaches to the E300 electronic overload relay to provide DeviceNet network connectivity. It serves as the interface between the E300 and a DeviceNet master node (for example, an Allen-Bradley 1756-DNB), enabling the relay to transmit status information and receive control or diagnostic data over the network. The module is described as the DeviceNet communication option for the E300 overload relays within the 193-ECM-DNT family, and it is designed to integrate motor protection functionality with a DeviceNet bus for applications requiring remote monitoring and coordination with a centralized control system. In practice, it supports plant-wide DeviceNet integration of the E300’s protection features, facilitating access to overload status, fault conditions, and operational readiness from the network.
