Description
The Allen-Bradley 1752-L24BBBE SmartGuard 600 Safety Controller is a programmable electronic safety system for industrial machine safety applications requiring high-integrity control and monitoring. 1752-L24BBBE serves as the central safety logic processor within the SmartGuard 600 family, executing safety functions while managing safety I/O and communication with other safety devices on the network.
1752-L24BBBE is certified for use in safety applications up to and including Safety Integrity Level (SIL) 3 according to IEC 61508, Performance Level PL(e) according to ISO 13849-1, and Category 4 according to EN 954-1. These certifications of 1752-L24BBBE make it suitable for the most demanding safety applications where failure could result in serious injury, including press guarding, robotic work cells, conveyor systems, and automated machinery with hazardous motion.
The I/O configuration of 1752-L24BBBE includes 16 digital inputs for connecting safety devices such as light curtains, safety switches, and emergency stop buttons; 8 digital outputs for controlling safety actuators such as contactors and safety relays; and 4 test pulse sources for dynamic testing of input circuits. The safety outputs of 1752-L24BBBE are designed with internal monitoring to detect faults such as short circuits and ground faults, ensuring that output failures are detected and the system transitions to a safe state.

Wiring & Connections
Features:
- SIL 3 / PL e / Category 4 Safety Certification
- 16 Digital Inputs, 8 Digital Outputs, and 4 Test Pulse Sources
- Dual Communication Interfaces (DeviceNet + EtherNet/IP)
- USB Programming and Configuration Port
- DIN Rail Mounting with Horizontal Orientation Requirement
- Front-Panel Status Indicators and Rotary Switches
The controller integrates 16 safety-rated digital inputs, 8 safety-rated digital outputs, and 4 pulse test sources in a single compact unit. The pulse test outputs (T0–T3) are used for muting lamp control and external device monitoring (EDM) in light curtain and safety gate applications. Total simultaneous current for all test outputs is limited to 1.4 A.
The 1752-L24BBBE Allen-Bradley SmartGuard 600 Safety Controller may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Power consumption is 280 mA at 24 V DC with a heat dissipation of 9.3 W at maximum load. The controller requires RSNetWorx for DeviceNet V9.1 or later for configuration and programming. The 1752-L24BBB (without EtherNet/IP) requires RSNetWorx V8 minimum.
Typical applications include multi-zone safety control, complex light curtain muting (e.g., robot load zone monitoring with enable pendant), safety interlocking between multiple controllers, distributed safety I/O architectures, and integration of safety and standard control on a single network. The SmartGuard 600 is particularly cost-effective for applications with 6 to 16 safety inputs and 4 to 8 safety outputs where a GuardLogix would be oversized.
- Automotive Assembly: Manages robotic cells, safeguarding light curtains, e-stops, and interlocking logic
- Packaging/Bottling: Halts high-speed machinery via access doors, interlocks, and e-stop circuits
- Material Handling: Coordinates emergency stops across conveyors, sorters, and storage systems
- Metalworking/Press: Manages two-hand controls, light grids, and perimeter gates for stamping equipment
- Food/Beverage: Monitors safety boundaries in washdown environments without interfering with automation

Power Supply: Wire 24V DC power (20.4--26.4V DC range) to the controller’s power terminals. Ensure the DeviceNet network is also powered appropriately.
Safety I/O & Devices: Connect field devices directly to the 16 safety-rated inputs and 8 safety-rated outputs. Use the 4 test pulse sources for short-circuit and cross-fault diagnostics on connected safety sensors.
Communication:DeviceNet: DeviceNet is mandatory for controlling safety I/O. Connect to your DeviceNet network via the integrated 5-pin open style connector.
Ethernet/IP: The Ethernet port on the 1752-L24BBBE cannot control I/O directly. Use it for programming, HMI/SCADA communication, or data pass-through using a standard Category 5 Ethernet cable.
USB: Use the USB port for direct connection and troubleshooting.
Technical notes
The front panel of 1752-L24BBBE includes status LED indicators for module status (MS), network status (NS), lock status, and communication status (COMM). The two-digit seven-segment display of 1752-L24BBBE shows the DeviceNet node address and diagnostic information. Two rotary switches on the front panel of 1752-L24BBBE are used to set the DeviceNet node address from 00 to 63, with a DIP switch for setting the communication rate (125 kbps, 250 kbps, or 500 kbps). The default DeviceNet communication rate for 1752-L24BBBE is 125 kbps.
