Product Description

The Arteche BJ8BB is a high-performance, robust Digital Input (DI) and Digital Output (DO) Module designed for reliable integration into Substation Automation Systems (SAS) and industrial control panels. It serves as a reliable interface between the physical status of equipment (switches, breakers, sensors) and the control logic (PLC, RTU, or protection relay).

• Type: Digital Input/Output (I/O) Module for Auxiliary Relays and Control Systems.

• Function: It is used to acquire status signals (DI) from field equipment and to transmit control commands (DO) to devices like circuit breaker trip coils or signaling lamps.

• Design: Built to meet the stringent requirements of the energy sector, featuring high electromagnetic compatibility (EMC) and surge immunity.

• Modularity: It is often part of a modular system, connecting to a central processing unit (CPU) or communication gateway.

Product Specifications

Since the exact configuration of the BJ8BB can vary based on the series (e.g., if it’s a component of a larger Arteche system or a standalone auxiliary relay), the following specifications are typical for a module in this class:

Product Advantages

• High Reliability and Durability: Designed specifically for critical environments like substations, the BJ8BB is built with high-quality components to ensure long operational life and reliability, especially in high-vibration or high-surge conditions.

• Exceptional Immunity: Offers superior immunity to electromagnetic interference (EMI) and power system transients (surges), which are common in electrical substations, ensuring signals are not corrupted.

• Voltage Flexibility: The inputs are typically available to accept a wide range of standard substation control voltages, simplifying inventory and installation across different projects.

• Galvanic Isolation: Provides robust galvanic isolation between the control system and the field equipment, enhancing safety and protecting sensitive electronics.

• Fast Response Time: Critical for protection and control, these modules are designed for fast detection of input status changes and quick activation of output relays.

Precautions

• Control Voltage Matching: The auxiliary power supply voltage and the input voltage range of the module must exactly match the available control voltage in the panel (e.g., $110\,\text{V DC}$ module requires $110\,\text{V DC}$ supply).

• Wiring Standards: Use proper wiring techniques and ensure all connections are torqued correctly. Maintain separation between low-level signal cables and high-power cables to minimize interference.

• Inductive Load Protection: While the output relays are robust, external surge suppression (snubbers, varistors) should be used across highly inductive loads (like circuit breaker trip/close coils) to protect the relay contacts from premature wear due to arcing.

• Configuration: If the BJ8BB is part of a larger communication system, it must be properly addressed and configured in the central control software (e.g., RTU or PLC programming environment).

• Grounding: Ensure the module is properly grounded in accordance with the manufacturer’s instructions and local substation grounding practices for optimal noise immunity.

Product Applications

The Arteche BJ8BB module is vital in electrical power systems and critical infrastructure where reliable status monitoring and control actuation are necessary.

• Substation Automation Systems (SAS):

  • Status Monitoring: Receiving Digital Inputs from circuit breaker auxiliary contacts (open/closed status), disconnect switches, and protection relay trip signals.

  • Trip/Close Control: Providing Digital Outputs to energize circuit breaker trip/close coils.

• Process Control and SCADA:

  • Interfacing between a central SCADA/RTU system and field devices that require high-voltage DC signaling.

• Auxiliary Relays and Control Panels:

  • Used in general control panels to provide reliable isolation and amplification of signals for sequencing and interlocking operations.

• Power Generation:

  • Monitoring the status of turbines, generators, and synchronizing equipment.
