The 193-EC1DE relay is an electronic overload relay unit that is designed and manufactured by Allen-Bradley/Rockwell Automation. These overload relays are available in 2 configurations and they are available through the Bulletin 193-EC product line. The 193-EC1DE unit is an E3 relay variant that comes with 2 inputs and 1 output. The unit features thermal overload capabilities that include the adjustable settings, thermal utilization, thermal memory, time to reset, and the time to trip capability. Besides that, the 193-EC1DE overload relay comes with other capabilities for phase loss, ground fault, stall, underload, remote trip, and over-temperature protection. Also, the unit has advanced diagnostic capabilities and it comes with status indicators for the trip status, device status, warning status, number of starts status, and the hours of operation status.

The 193-EC1DE electronic overload relay has a rated insulation voltage of 690 Volts AC and a rated frequency of 20 to 250 Hertz. The adjustable current rating of the unit is 9 to 45 Amps. The unit is compatible with a DeviceNet configuration terminal that can be used for various operations like programming, monitoring, configuration, and commissioning. The unit provides protection for single-phase and three-phase motors and it has an integrated inputs and outputs. The 193-EC1DE overload relay has an adjustable trip class of 5 to 30 Amps. The unit operates in environments with an ambient temperature range from -20 to 55 degrees Celsius (-4 to 131 degrees Fahrenheit) and it can be stored in an area with a wider temperature range. The specified relative humidity range is 5 to 95% (non-condensing). The component has an approximate weight of 1.2 kilograms (2.7 pounds) and small dimensions.
