Information About 193-EA1FB

The 193-EA1FB relay by Allen-Bradley is an electronic overload relay that is used for motor protection. The modular design, diagnostic information, communication options, integration to Logix technology, and simplified wiring make this relay the best overload relay for motor control applications in automation systems. This electronic overload relay comes with a number of benefits, including intelligent motor control which is DeviceNet and EtherNet/IP enabled. Moreover, the Allen-Bradley 193-EA1FB relay comes with an integrated I/O, which assists in providing diagnostic information as well as scalable solution. The relay has an adjustable trip class of 5 to 30, warning settings, a programmable trip range, and a wide current range. The 193-EA1FB relay comprises 3 modules which are sensing, communications, and control modules. The users have an option for each of the 3 modules with extra accessories to customize the relays to suit their own exact needs.

The Allen-Bradley 193-EA1FB electronic overload relay provides overload protection via the true RMS current measurement of each of the distinct phase currents of the connected motor. This module uses the information to calculate a thermal model, which gives a simulation of the actual heating of the motor. The percentage of the thermal capacity utilization or the %TCU gives a report of the calculated value, which is then read through a communications network. For an overload trip to occur, the value must reach 100%. The Allen-Bradley 193-EA1FB electronic overload relay has a thermal memory circuit which is designed to estimate the thermal decay in the Trip Class 20 settings. As a result, the thermal model of the connected motor is maintained even when there is no power supply connected to it.

Frequently Asked Questions about 193-EA1FB
Question: What is the 193-EA1FB?
Date Update:16/06/2025
Answer:

The 193-EA1FB is an electronic overload relay from Allen-Bradley’s E1 Plus series, designed to provide advanced motor protection in industrial automation systems. It protects motors from overload conditions by continuously monitoring the true RMS current of each phase. This data is used to calculate a thermal model of the motor, ensuring precise trip behavior. The relay includes built-in diagnostics and programmable trip settings. It’s ideal for smart motor control centers and integration with Logix-based systems.

Question: What trip class does it use?
Date Update:16/06/2025
Answer:

By default, the relay is set to Trip Class 10, which defines the thermal time-delay characteristics of the overload trip. However, the trip class is adjustable between 5 and 30, offering flexibility for various motor types and applications. This allows protection to be tailored for standard, high-inertia, or high-cycling motors. Trip class settings determine how quickly the relay responds to overload conditions. Accurate selection ensures both protection and motor longevity.

Question: Does it support communications?
Date Update:16/06/2025
Answer:

Yes, the 193-EA1FB is communication-enabled, supporting DeviceNet and EtherNet/IP protocols via optional modules. This allows integration with Rockwell’s Logix control systems for real-time diagnostics and control. Users can monitor parameters such as %TCU (thermal capacity utilization), phase loss, and trip history remotely. Communication enhances predictive maintenance and system transparency. It also reduces wiring complexity in large motor installations.

Question: What temperature range does it support?
Date Update:16/06/2025
Answer:

The 193-EA1FB operates reliably within a temperature range of -20°C to +40°C, making it suitable for most factory and field installations. For extended temperatures, ventilation or enclosure climate control may be required. The electronics are rated for thermal stability and protection accuracy within this range. High ambient temperatures may slightly reduce trip accuracy unless derated. The relay is designed to maintain precision in standard industrial environments.

Question: What type of protection does it offer?
Date Update:16/06/2025
Answer:

The relay provides thermal overload protection using true RMS current sensing for each phase. It calculates a dynamic thermal model of the motor to determine when an overload condition exists. It also includes thermal memory, allowing the relay to simulate cooling time when the motor is powered off. This protects against repeated quick starts that could overheat the motor. It ensures accurate protection even during power loss or restarts.
