- Outputs: 6 Relay and 6 Protected FET Outputs (3 at 100kHz)
- Communication: Ethernet/IP, 2 Serial Ports
- Motion Support: Up to 3 axes of Pulse Train Output (PTO)
Technical Superiority: The Motion-Ready MicroLogix 1400
The 1766-L32BXB is designed for performance-driven automation. Unlike the relay-only BWA models, the L32BXB features 6 high-speed FET outputs. Three of these outputs are capable of 100kHz pulse generation, allowing for the direct control of servo drives and stepper motors in open-loop positioning tasks. The input section is equally impressive, with 12 inputs supporting 100kHz high-speed counting. This combination of fast sensing and fast acting makes the 1766-L32BXB a powerhouse for «cut-to-length» systems, precision labeling, and any process where millisecond timing is critical. Its 24V DC power requirement makes it perfect for panels with centralized DC distribution and safety-critical environments where high-voltage AC is restricted.
Installation Advice: Protecting FET Outputs and High-Speed Signals
When wiring the 1766-L32BXB, signal integrity is the most important factor. Use shielded cabling for all PTO and encoder connections, grounding the shield at the chassis only. The 6 FET outputs are «protected,» meaning they will shut down during a short circuit to prevent hardware failure; however, they are strictly for DC loads. A common error is attempting to drive an AC solenoid with a FET output, which will immediately destroy the transistor. For inductive DC loads, always install a flyback diode. Because the 24V DC power is shared between the logic and the outputs, ensure your power supply is regulated and sized to handle the inrush current of your actuators to prevent processor resets.
Maintenance and Hardware Integrity
The 1766-L32BXB is a solid-state device with a long mechanical life compared to relay units. However, thermal care is essential; high-density FET switching generates heat. Ensure your control cabinet has adequate ventilation to keep the ambient temperature below 60°C. Periodically verify the firmware version via the embedded web server to ensure compatibility with modern EtherNet/IP devices. Sourcing your 1766-L32BXB from Atlantechdrives ensures you get a fully tested unit with the latest hardware revisions, providing the timing precision required for your most demanding motion control projects.
FAQs
