ABB 1TGE120021R0010

Description

Product Overview

The ABB 1TGE120021R0010 is a specialized digital input/output (I/O) module designed for ABB’s Relion® 615 series of protection and control relays. This module serves as a critical expansion unit, providing additional binary (on/off) signal interfaces to enhance the relay’s capability to interact with the primary equipment in a substation. The ABB 1TGE120021R0010 module allows the RED615, REF615, or other 615 series relays to monitor more status contacts (like circuit breaker position, isolator status, or pressure alarms) and command more control outputs (for tripping, closing, or alarm annunciation). By integrating the ABB 1TGE120021R0010, engineers can customize the I/O capacity of the relay to precisely match the requirements of a specific feeder or bay, eliminating the need for external auxiliary relays in many cases. This module exemplifies the modular and scalable design philosophy of the Relion platform.

Product Parameters and Specifications

• Manufacturer: ABB

• Product Series: Relion® 615 Series Expansion I/O.

• Module Type: Digital Input/Output Expansion Module.

• Compatibility: Designed for use with ABB Relion 615 series protection relays (e.g., RED615, REF615, REJ615) as a plug-in expansion unit.

• I/O Configuration: Typically provides a combination of binary inputs and outputs. The exact count and type (e.g., 8 BI + 4 BO) are defined by this specific part number.

  • Binary Inputs (BI): For monitoring dry contacts (statuses). They are typically rated for 24-250V DC.

  • Binary Outputs (BO): Form C relay contacts (changeover contacts) for control commands like trip/close or signaling. These are rated for a specific current and voltage (e.g., 250V AC/DC, 5A).

• Mounting: Plugs directly into a dedicated expansion slot on the side or rear of the compatible Relion 615 relay.

• Communication: Integrates with the main relay via a direct internal bus, requiring no additional communication configuration.

• Power Supply: Powered internally from the host relay.

• Standards: Designed to meet relevant IEC and IEEE standards for substation automation equipment.

Advantages and Key Features

1. Customizable I/O Capacity: The primary advantage of the ABB 1TGE120021R0010 is that it allows users to scale the I/O points of a standard protection relay to fit complex applications, providing a cost-effective alternative to purchasing a larger, more expensive relay model or adding external marshalling cabinets.

2. Seamless Integration and Configuration: As a genuine ABB expansion module, it is automatically recognized by the host relay. Configuration of the new I/O points is done within the same PCM600 engineering tool used for the relay itself, ensuring a unified and consistent configuration environment.

3. High Reliability in Harsh Environments: Built to the same stringent standards as the main relay, the ABB 1TGE120021R0010 is designed for the high electromagnetic interference (EMI), temperature variations, and long service life required in electrical substations.

4. Reduces External Wiring and Components: By providing additional built-in relay outputs, it can often eliminate the need for external auxiliary trip relays, reducing panel space, wiring complexity, and potential points of failure.

5. Maintains System Integrity: Using the dedicated expansion module preserves the relay’s certifications and ensures full compatibility, unlike using generic external I/O which could introduce integration and reliability issues.

Application Case Studies

• Complex Ring Main Unit (RMU) Protection: For a 2-circuit RMU with sectionalizing switches, the standard I/O on a RED615 relay might be insufficient. Adding the ABB 1TGE120021R0010 provides extra binary inputs to monitor all switch positions (2 breakers + 1 sectionalizer) and extra outputs to control all three mechanisms and signal local/remote status.

• Transformer Feeder with Multiple Alarms: Protecting a transformer feeder requires not just overcurrent protection but also monitoring of transformer ancillary equipment. The expansion module adds inputs for Buchholz relay, winding temperature, oil level, and pressure relief device alarms, allowing a single relay to manage both protection and comprehensive condition monitoring.

• Automated Feeder with Recloser Control: In an application requiring a reclosing sequence with status feedback for each attempt, the additional outputs from the 1TGE120021R0010 can be used for the close commands, while the extra inputs confirm the breaker status after each close operation, enabling sophisticated logic within the relay.

Selection Suggestions and Important Notes

• Selection Suggestion:

  • Select the ABB 1TGE120021R0010 when you have a Relion 615 series relay and the application requires more binary signals than the relay’s standard version provides.

  • It is the preferred choice during the initial panel design phase to optimize the I/O layout, or as a retrofit to add functionality to an already installed relay without replacing the entire unit.

  • Choose this module when you want to keep all control logic and I/O within the certified environment of the protection relay, maintaining a simple, single-vendor solution.

• Important Notes:

  • Compatibility Check: Before ordering, verify the compatibility of the ABB 1TGE120021R0010 with the exact model and hardware version of your Relion 615 relay using ABB’s compatibility lists or product manuals.

  • Firmware Compatibility: Ensure the firmware version of the host relay supports the expansion module. An update may be required.

  • Mechanical Fit: Confirm the physical space in the panel allows for the attachment of the expansion module to the side of the relay without obstruction.

  • I/O Point Mapping: During configuration in PCM600, carefully map the new I/O points from the 1TGE120021R0010 to the appropriate functions (e.g., specific protection start signals, control commands) in the relay’s application configuration.

  • Ordering the Correct Variant: The part number 1TGE120021R0010 is specific. Other suffixes (e.g., R0020) may denote different I/O configurations (e.g., more inputs vs. more outputs). Always confirm the exact I/O structure meets your needs.
