- Part of the SmartGuard 600 series
- Specialized safety controller that features numerous connectivity options
- This unit provides 16 digital inputs and 8 digital outputs, supporting various control configurations
The 1752-L24BBBE safety controller is part of the Allen Bradley SmartGuard 600 series, designed to meet the complex control needs of industrial environments. This controller handles 16 digital inputs and 8 digital outputs, providing great flexibility in system configuration and monitoring. Its nominal operating voltage is 24V DC, and it can operate effectively within a DC voltage range of 20.4 to 26.4V. The device operates at a frequency range of 50 to 60 Hz, ensuring compatibility with a wide range of applications.
Furthermore, its current consumption is only 280 mA, making it energy efficient. The controller features a maximum inrush current of 4.8 amps for a duration of only 600 microseconds, providing the necessary surge capacity during startup. Data transmission is possible through multiple communication ports, including Ethernet, DeviceNet, and USB, making it ideal for integration into modern control systems. Ethernet data rates support a range of 10 to 100 Mbps, enabling effective communication bandwidth.
The 1752-L24BBBE Allen Bradley SmartGuard 600 Safety Controller Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

1.Robotic Welding and Assembly Work Cells: Manage safety interlocks between robot controllers, light curtains, emergency stop buttons, and safety door interlocks. It handles complex logic locally (e.g., zone mute or delayed safety stops) and reports cell status to the central master PLC via Ethernet/IP.
2.Material Handling and Conveyor Interlocks: Used to connect different conveyor sections. Multiple SmartGuard units can perform point-to-point safety interlocks via a network to coordinate long-distance safe speed limits or emergency stops.
3.Packaging and Filling Lines: Coordinate high-density local safety devices. The controller acts as a DeviceNet Safety master, collecting data from Guard I/O distributed modules around the machine to perform high-speed local safety stops up to SIL 3/PLe standards.
4.Safe Motion Control (Speed and Position Monitoring): Works with safe power-off motor starters, frequency converters (e.g., PowerFlex), and speed monitoring relays to manage complex safe speed limits or safe direction applications within maintenance cycles.
This software integrates over 10 dedicated safety function modules to handle various common safety devices:
1.Emergency Stop (E-Stop): Supports dual-channel architecture with built-in **time deviation** monitoring to prevent contact sticking.
2.Light Curtain Monitoring: Used for light curtain control, integrating manual/automatic reset logic.
3.Safety Door Monitoring: Monitors the opening and closing of safety doors, supporting open/lock logic and crosstalk detection.
4.Two-Hand Control: Monitors the synchronization of two-hand buttons, requiring both input buttons to be pressed simultaneously within 500 milliseconds for effectiveness (compliant with Class IIIC standards).
5.Silence (Light Curtain Shielding): Supports shielding logic for 2 or 4 sensors, allowing temporary shielding of safety protection devices during specific processes (e.g., workpiece entry/exit).
