Configured for discrete machine control through relay and solid-state outputs, the Allen-Bradley 1762-L24BXBR (1762-L24BXBR Programmable Controller) provides 24 VDC input processing, high-speed input capability, and mixed output circuitry.

Model Identification

The supplied product information identifies 1762-L24BXBR as an Allen-Bradley MicroLogix programmable controller. The provided data does not explicitly state the MicroLogix sub-series name, so no additional series designation is assigned beyond the supplied product family reference.

Hardware Specifications

I/O and Control Architecture

The controller combines 24 VDC discrete inputs with mixed relay and FET output circuitry. The input section contains 10 standard 24 VDC inputs and 4 fast 24 VDC inputs.

The output section contains 5 relay outputs, 4 standard 24 VDC FET outputs, and 1 high-speed 24 VDC FET output. This arrangement permits relay switching and solid-state output functions within the same controller.

The supplied data does not define the exact switching frequency, pulse width, minimum load current, or electrical isolation characteristics of the individual FET outputs.

Communication and Firmware Considerations

The controller provides one 8-pin mini-DIN serial communication port and one programming port according to the supplied specifications.

Communication protocol details, baud-rate limits, programming software revision, memory capacity, and firmware compatibility are not included in the supplied data. These parameters should be verified against the applicable MicroLogix documentation before system integration or replacement.

Installation and Wiring Guidelines

• Verify the controller supply requirements before applying power.
• Confirm that the input circuits are compatible with the specified 24 VDC input signals.
• Separate relay output wiring from low-level control and communication wiring where practical.
• Check the load voltage and current against the applicable relay and FET output specifications before connection.
• Do not assume that relay and FET outputs have identical switching characteristics.
• Observe the specified relay contact voltage range of 24-125 VDC or 120-240 VAC.
• Provide suitable overcurrent protection for connected field circuits.
• Verify serial and programming cable pin assignments before connection.
• Keep communication wiring away from high-current switching conductors where practical.
• Account for the listed power-supply inrush current during upstream protection and power-distribution design.
• Do not hot-swap the controller unless the applicable Allen-Bradley documentation explicitly permits live replacement.
• Confirm controller configuration and firmware compatibility before transferring an existing control program.
