The 1752-L24BBBE is a dedicated safety controller within the SmartGuard 600 family, engineered for diverse network integration. This module comes equipped with a hardware density of 16 digital safety inputs and 8 digital safety outputs, accommodating a wide range of protective control architectures.
Integrated 16 in / 8 out in a compact footprint, delivering efficient safety control for mid-to-small systems without a large PLC
Supports DeviceNet Safety with transparent bridging to EtherNet/IP for multi-network data sharing
Complies with the highest SIL 3, PLe, and Cat. 4 standards, ensuring reliable compliance for high-risk protection
The device operates on a nominal 24V DC power supply (with an allowable range of 20.4 to 26.4V DC), aligns with 50/60 Hz applications, and maintains a low running current of 280 mA while possessing the capacity to handle a startup inrush current of 4.8 A lasting 600 microseconds. To facilitate seamless integration into modern control systems, the controller features multiple communication interfaces, including Ethernet (supporting 10/100 Mbps), DeviceNet, and USB. In terms of electrical and environmental adaptability, it features an input impedance of 2.6 kΩ, a DeviceNet network load of 15 mA, and a single-point output drive current of 0.5 A, all enclosed in an IP20-rated housing that limits full-load heat dissipation to 9.3 W for stable thermal management in harsh industrial environments.
The 1752-L24BBBE utilizes a standard DIN rail snap-on method, simplifying its layout within various standard control cabinets. Its internal firmware and safety logic can be intuitively configured via dedicated software, which not only streamlines the creation of safety matrices but also supports online status monitoring and device health diagnostics. Whether deployed for interlocking control in conveyor zones or safety zoning in complex multi-axis robotic workcells, this controller functions efficiently as either an independent safety island or a networked distributed safety node, delivering exceptional response speeds and high noise immunity.

Electronics & Semiconductor Manufacturing
Monitored enclosure interlock switches in high-speed surface mount (SMT) machines and wafer dicing equipment to instantly halt high-risk motion axes if the protective cover is opened.
Metal Processing & Machine Tool Industry
Applied to high-power CNC machines, metal bending machines, and hydraulic presses to manage dual-hand control buttons and safety mats, ensuring the operator's hands leave the hazard zone before press initiation.
Plastics & Injection Molding Industry
Worked with large injection molding machines and take-out robots to monitor safety doors and overlapping robot motion paths in real time, preventing crushing accidents during mold closing.
Rubber & Tire Manufacturing Industry
Used in internal mixers, tire building machines, and curing presses, cutting power via safety photoelectric sensors and safety edges when operators approach high-temperature or high-torque rollers.
Water Treatment & Environmental Equipment
Managed safety limit switches around open-air moving structures in large sludge scrapers, aerators, and waste compaction stations, preventing inspection personnel from slipping or accidentally entering pinch points.
Printing & Paper Processing Industry
Centrally managed long-distance distributed pull-wire emergency switches on large multi-color printing presses, rotary paper cutters, and corrugated cardboard lines to quickly respond to line-wide emergency braking commands.
During the use of 1752-L24BBBE, it is mandatory to ensure correct wiring of dual-channel safety circuits and regularly test pulse outputs to prevent external short-circuit faults. Additionally, perform any DIN rail mounting or wiring changes only after complete power-off, and periodically inspect the cabinet ventilation and protective meshes to ensure the operating environment remains within the specified 24V DC voltage and temperature limits, preventing accidental safety controller lockups due to electrical overload or localized heat accumulation inside the enclosure.
The 1752-L24BBBE features a diagnostic panel equipped with MS, NS, Lock, and COMM LED indicators, alongside a 2-digit, 7-segment display for node addresses and error codes. Users can assign the DeviceNet node address (00–63) via dual rotary switches and select the communication rate (125, 250, or 500 kbps) using the integrated DIP switch.
