Rockwell Automation has expanded its overload relay family with the new Allen-Bradley 193-EC5 E3 Plus solid-state overload relay, featuring voltage protection and energy monitoring.
Part of the E3 Plus family, the new overload relay combines current and voltage protection with enhanced power monitoring and diagnostic capabilities, helping users improve energy efficiency and safeguard critical electric motor loads, according to Rockwell Automation.
This capability helps speed troubleshooting, minimise downtime and reduce energy costs, the company says.
The new overload relay is specially designed for low voltage applications in materials handling, water/wastewater, process, petrochemical, and minerals and mining.
Communicating status and diagnostic information using DeviceNet communications with Rockwell Software RSEnergyMetrix software, the new overload relay identifies motors contributing to the monthly peak demand and power factor line items on utility bills.
It also assists in activity-based cost accounting and verifying energy-reduction initiatives.
In addition, the overload relay is equipped with Allen-Bradley DeviceLogix Intelligent Component Technology, which integrates logic-solving capability into the overload relay.
This provides users with basic digital control when a programmable controller is not available. It also can be used to turn off a motor in the event of lost communications within a control system, Rockwell Automation says.
