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

The 193-ECM-DNT is Allen‑Bradley’s DeviceNet communication module for the E300 electronic overload relay family, providing a DeviceNet interface that enables the E300 to communicate on a DeviceNet network. When used with a DeviceNet master such as a 1756‑DNB, it enables exchange of relay status and trip information between the E300 and the control system, and it is configured with RSNetWorx for DeviceNet to assign the device address and data rate. A blue reset button on the communication module allows resetting the relay trip state through network communications or digital inputs, reflecting the E300’s protection status in the networked system. The module integrates with the E300 protection logic to extend connectivity for industrial motor protection schemes that rely on DeviceNet for monitoring and control. Rockwell's release materials document the 193-ECM-DNT’s firmware applications with revisions such as 1.001–1.003 across Series A/B, underscoring ongoing updates and compatibility within the E300 family.
