Information About 1762-L40BXBR 

The 1762-L40BXBR is part of the Allen-Bradley MicroLogix 1200 series, built to deliver modular expandability and broad protocol compatibility in industrial automation systems. It supports up to six expansion modules, allowing users to scale I/O capacity as system requirements grow. The controller integrates a Mini-DIN serial port that supports DF1, DH-485, ASCII, and Modbus communication, enabling easy connection to HMIs, SCADA systems, and external devices. Its durable construction, wide operating temperature range, and long mechanical relay life make it well suited for demanding installations.

Key Features:

  • Mixed I/O Architecture: Provides 20 standard DC inputs, 4 fast DC inputs, 8 relay outputs, 7 DC FET outputs, and 1 high-speed FET output for flexible control.
  • Expandable Design: Supports up to six 1762 expansion modules to increase system capacity.
  • Versatile Communications: Includes an 8-pin Mini-DIN serial port for DF1, DH-485, ASCII, and Modbus protocols.
  • High Relay Durability: Rated for 20 million mechanical cycles with AC and DC switching capability.
  • Robust Electrical Ratings: Handles 24–125 VDC and 120–240 VAC relay loads with defined current and isolation specifications.
  • Industrial Environmental Tolerance: Operates from 0 to 55 °C and withstands 30 G shock and 5 G vibration.
  • Integrated Trim Pots: Two onboard potentiometers enable local adjustments to internal registers for testing or simulation.
  • Compact Mounting Options: Supports panel or DIN-rail installation for flexible deployment in control cabinets.

The 1762-L40BXBR delivers the reliability and precision required for stable machine sequencing and discrete automation control.

Frequently Asked Questions about 1762-L40BXBR
Question: What are the key electrical specifications of the 1762-L40BXBR?
Date Update:03/06/2025
Answer:

The key electrical specifications of the 1762-L40BXBR are as follows:

  • Power supply voltage: 24V DC input power.
  • Power consumption: 40 Watts maximum.
  • Relay output ratings: 24-125V DC and 120-240V AC.
  • FET output ratings: 24V DC.
  • Output currents: 600mA at 5V DC, 500mA at 24V DC.

These specifications ensure the reliable operation of the controller in various industrial environments.

Question: How does the 1762-L40BXBR handle communication with external devices?
Date Update:03/06/2025
Answer:

The controller is equipped with an 8-pin mini-DIN port that supports RS232 (DF1), DH-485, ASCII, and MODBUS protocols. This allows the PLC to communicate with a wide variety of devices, including Human-Machine Interfaces (HMI), Supervisory Control and Data Acquisition (SCADA) systems, and other intelligent electronic devices. The flexible communication ensures seamless integration into existing control systems. Users can configure these protocols through the programming software.

Question: Does the 1762-L40BXBR have isolation between inputs and outputs?
Date Update:03/06/2025
Answer:

Yes, the controller provides isolation between input groups and the backplane, as well as between the FET output group and the backplane. It features 75V DC isolation voltage between inputs and outputs, tested at 1200V AC for 1 second. Relay outputs have IEC Class 2 reinforced insulation, tested at 1836V AC for 1 second. This isolation enhances system safety and minimizes interference. Proper grounding and installation practices are essential for maintaining isolation.

Question: Which applications benefit most from using the 1762-L40BXBR?
Date Update:03/06/2025
Answer:

This PLC is ideal for small to medium-sized automation systems requiring a mix of digital and high-speed outputs. Common applications include controlling machinery, packaging systems, and industrial processes with moderate I/O requirements. Its compatibility with standard communication protocols ensures integration with SCADA and HMI systems. It’s also useful in applications that need modular expansion. The device’s rugged design supports industrial environments.

Question: Is the 1762-L40BXBR still in production?
Date Update:03/06/2025
Answer:

No, the 1762-L40BXBR has been discontinued as of August 25, 2021, and is no longer available for purchase from Rockwell Automation. Customers are encouraged to transition to the recommended replacement product, the Micro850, to maintain system compatibility and support.
