Product Summary
The 1762-L40BWA is a powerful 40-point Programmable Logic Controller from Rockwell Automation. This MicroLogix 1200 unit offers a robust solution for discrete control applications. It delivers twenty-four DC inputs and sixteen relay outputs for demanding tasks.
Product Procurement & Buyer Guide
The 1762-L40BWA provides a reliable control platform for system integrators. This controller accepts 120 to 240 Volts AC for its input power. It operates on a standard industrial frequency of 47 to 63 Hertz.

This model features twenty-four discrete inputs for 24 Volts DC signals. The input circuit type supports both sinking and sourcing wiring configurations. This flexibility simplifies connections to various sensors and switches. Four of these inputs are designated as fast inputs for high-speed counting.
The output side includes sixteen relay contacts. The relay contact rating handles 24-125 Volts DC or 120-240 Volts AC. Each relay can switch a minimum load current of 10 Amps. The mechanical life of these relays reaches 20,000,000 cycles. This ensures long-term reliability in high-cycle applications.
Integrating this controller into a system requires careful planning. The integrated 8-pin Mini DIN RS232 communication port supports multiple protocols. It works with DH-485, DF1, Modbus, and ASCII protocols. DF1 and Modbus operate in a peer-to-peer configuration. For network bus connections, you may need an external converter like the 1761-NET-AIC.
Expert Technical Evaluation & Performance Review

This PLC is an electronic device that needs proper enclosure protection. The ambient operating temperature range is 0 to 55 degrees Celsius. You must maintain the enclosure temperature within this range. Install climate control devices like heaters or fans as needed.
The power supply usage is 82 VA. The power supply inrush current is 25A for 8 ms at 120V ac. At 240V ac, the inrush current is 40A for 4 ms. This information is critical for designing your power distribution system.
The internal power supply simplifies installation by reducing external component needs. The controller supports DIN Rail or Panel Mounting for flexible installation. Its dimensions are 90 mm height by 160 mm width by 87 mm depth.
Mounting this controller inside a suitable enclosure is a standard requirement. The enclosure must provide adequate protection against environmental factors. You should consider using appropriate climate control devices for your location.
