193-EC1ZZ 193-EIMD Allen-Bradley

193-EC1ZZ 193-EIMD Allen-Bradley I / O module

Product  Description：

The 193-EC1ZZ serves as the primary Control and Communication Module for the E3 Plus series. It is a microprocessor-based device that handles the logic, protection algorithms, and network communication (typically DeviceNet) for the motor starter. Unlike integrated versions that include current sensors, the "ZZ" designation indicates that this module is designed for use with external current transformers (CTs), allowing it to protect motors with high current ratings by interfacing with a 5A secondary CT.

The 193-EIMD is an Expansion I/O Interface Module specifically designed to snap onto the E3 Plus core. Its primary function is to increase the digital input density of the relay. This module provides four additional AC inputs (110–120V AC), allowing the system to monitor external field devices such as limit switches, float switches, or auxiliary contactor status without requiring separate PLC input cards.

Product Parameters

193-EC1ZZ Control Module

• Current Adjustment Range: 9 to 5000 Amps (via external current transformers with 5A secondary).

• Network Protocol: DeviceNet.

• Inputs/Outputs: Includes integrated digital inputs and relay outputs for motor control.

• Protection Functions: Thermal overload, phase loss, current imbalance, stall, jam, and underload.

• Reset Types: Configurable for Manual or Automatic reset.

• Insulation Voltage: Rated for up to 600V AC (NEMA) or 690/1000V AC (IEC).

193-EIMD Expansion Module

• Input Type: Digital AC Input.

• Number of Inputs: 4.

• Rated Voltage: 110V AC to 120V AC.

• Frequency: 50/60 Hz.

• Compatibility: Exclusively for use with 193-EC and 592-EC series E3 Plus modules.

• Connection Type: Direct interface connection to the main relay body.

Product Advantages

• Advanced Diagnostics: The E3 Plus system provides real-time data including motor current, thermal usage, and fault history, which helps in predictive maintenance and reducing downtime.

• Space and Cost Efficiency: By using the 193-EIMD expansion module, users can wire field inputs directly to the overload relay. This reduces the need for long wire runs to a central PLC and saves space in the control cabinet.

• Integrated Logic (DeviceLogix): The 193-EC1ZZ supports DeviceLogix technology, enabling the relay to execute simple logic locally. This can provide faster response times for safety or interlocking tasks.

• Scalability: The modular design allows for a "mix and match" approach. You can use the same control module for a small motor or a massive high-voltage motor simply by changing the external CTs.

Important Considerations and Precautions

• Electrostatic Discharge (ESD) Sensitivity: Both modules contain sensitive electronic components. Always follow proper grounding procedures and handle the modules by the edges to prevent static damage during installation.

• External CT Accuracy: Since the 193-EC1ZZ relies on external current transformers, the accuracy of the protection is dependent on the quality and ratio settings of the CTs. Ensure the CT ratio is correctly programmed into the module parameters.

• Power Disconnection: Always isolate the main power and control power before attaching or removing the 193-EIMD expansion module. Plugging modules in while "hot" can damage the communication interface.

• Environmental Protection: These modules should be installed in a clean, dry industrial enclosure. Exposure to conductive dust or high moisture can cause internal short circuits.

• Phasing: When wiring the sensing circuit, ensure that the phase orientation matches the configuration in the software to avoid false "Phase Imbalance" or "Phase Loss" trips.

Product Applications

The combination of the 193-EC1ZZ and 193-EIMD is typically found in complex motor control centers (MCCs) across various industries:

• Oil and Gas: Monitoring large pump motors where ground fault and underload (dry run) protection are critical.

• Water and Wastewater: Integrating float switches directly via the 193-EIMD for automated tank level control.

• Mining and Metals: Protecting heavy-duty conveyors and crushers that require high-current monitoring and jam detection.

• Manufacturing Lines: Using DeviceNet to provide decentralized control and monitoring for multiple motor starters back to a central Allen-Bradley Logix controller.
