Overload relay offers motor diagnostics

Palatine, Ill. —A new solid-state overload relay offers remote programming with device parameters for “complete mid-range” motor protection and diagnostics to prevent downtime due to motor failures. Called Motor Logic Plus, the overload relay works as a stand-alone device or over an RS-485 or Modbus network. Up to 99 additional relayscan be networked and remotely controlled. Among protection features are high/low voltage, voltage/current unbalance, phase reversal, etc. Motor Logic Plus sets voltage setpoints, trip points, and restarts. It allows viewing of the last four faults and logging of selective diagnostics. www.squared.com
