Expert Procurement & Technical Evaluation
Scalable Safety Controller Platform
The 1768-L43S operates as a central safety controller. It integrates fully with the Compact GuardLogix product line. This module handles both standard and safety-critical processes. Its rackless I/O design simplifies cabinet installation. You save valuable panel space with this architecture. The controller offers unmatched scalability for growing applications.
Critical Performance Specifications
This module consumes 33.6 Watts of power maximum. Its power dissipation ranges from 4 to 7.5 Watts. The continuous backplane current sits at 1.4 Amps at 24 Volts. These values ensure efficient thermal management. The isolation voltage is rated at 30 Volts. You can rely on these specs for stable operation.
Robust Environmental Tolerances
The controller withstands harsh industrial environments. Its operating temperature spans 0 to 60 degrees Celsius. Storage temperatures range from -4 to 85 degrees Celsius. It handles non-condensing humidity from 5 to 95 percent. Vibration resistance measures 5 g at 10 to 500 Hertz. Operating shock tolerance is 30 g, and non-operating shock reaches 50 g. These tolerances guarantee reliable field performance.
Integrated Security and Motion Control
This controller provides built-in security controls. It also offers fully-integrated motion capabilities. The module works well on networked control systems. It uses EtherNet/IP or ControlNet for communication. Engineers benefit from this integrated design approach.
Installation and Safety Precautions
Always remove power before connecting any serial cables. An electric arc may occur otherwise. The module measures 5.18 x 3.55 x 4.8 inches. Its weight is only 15.9 ounces. This lightweight design aids easy handling. You can install it in Series A or B configurations.
Memory and Processing Capacity
The standard memory totals 2 MB of capacity. An additional safety memory provides 0.5 MB. This memory allocation handles complex safety programs. The processor executes logic efficiently within this footprint. Your applications gain both power and protection.
RF Immunity and Signal Integrity
The module offers radiated RF immunity at 10V/m. It operates with 1 kHz sine-wave 80% AM modulation. The frequency range spans 80 to 2000 MHz. This immunity prevents interference in noisy plants. Your control signals remain accurate and uncorrupted.
