2090-SCEP0-1 Allen-Bradley Power Board

Brand：Allen-Bradley Model number：2090-SCEP0-1

Country of origin: United States Product weight：0.55kg

HS code：8517623990

Product Details：

Product Dimensions：

The 2090-SCEP0-1 acts as a header or expansion plug that inserts into the Kinetix 6000 Integrated Multi-Axis (IAM) or Axis Module (AM). Its primary role is to bridge the safety signals across the drive’s power rail. In a multi-axis configuration, this plug is typically used to daisy-chain or terminate the safe-off signals, ensuring that the safety circuit is complete and that the drives can be enabled or disabled according to the safety logic of the machine.

Product Specifications

Product Type: Safe-off Connector Expansion Plug
Compatibility: Exclusively for use with the Kinetix 6000 (Series 2094) Servo Drive family
Connector Type: Header/Plug-in style for the drive's control interface
Safety Rating: When properly integrated, it supports systems designed to meet SIL 2 (IEC 61508) and PLd (ISO 13849-1) standards
Weight: Approximately $0.05 \text{ kg}$
Mounting: Direct plug-in to the front or side of the 2094 series modules
Material: Industrial-grade thermoplastic housing with high-conductivity contact pins

Product Advantages

Integrated Safety: It allows for the direct implementation of Safe Torque Off (STO), which disables the power transistors in the drive, preventing the motor from generating torque without removing power from the entire system.
Simplified Wiring: The 2090-SCEP0-1 reduces the complexity of safety wiring by providing a dedicated, standardized port for expansion, making it easier to manage multi-axis safety strings.
Cost-Effectiveness: By using a plug-based expansion system, users can avoid expensive and bulky external safety contactors for every axis.
Compact Design: The small footprint ensures it does not interfere with the high-density mounting of the Kinetix 6000 modules on the DIN rail or backplane.

Important Considerations

Proper Seating: Ensure the plug is fully seated and locked into the module. Loose connections can cause intermittent safety faults or prevent the drive from enabling.
Safety Validation: Installing this hardware is only one part of a safety system. The entire safety loop—including sensors, relays, and logic—must be validated by a qualified engineer to meet the required Performance Level (PL) or Safety Integrity Level (SIL).
Power Down Requirement: Never insert or remove the 2090-SCEP0-1 while the drive system is powered. High-voltage transients or logic errors may occur, potentially damaging the control board.
Correct Series Matching: Ensure your Kinetix 6000 drive modules are compatible with Safe Torque Off features, as older versions of the hardware may not support this specific expansion plug.

Product Applications

The 2090-SCEP0-1 is primarily used in industrial automation where operator safety and machine uptime are critical.

Packaging Machinery: Allowing operators to clear jams or perform routine maintenance without fully powering down the machine, thanks to the Safe Torque Off feature.
Robotic Work Cells: Integrating emergency stop (E-Stop) strings and light curtains directly into the drive's control logic.
Material Handling: Ensuring that conveyor belts or sorters can be safely neutralized during intervention while maintaining the communication state of the PAC.
Assembly Lines: Managing multi-axis motion where specific sections of the line need to be safely disabled while others continue to operate.
