Product Summary
The Allen-Bradley 1762-L40BXBR is a powerful, compact Programmable Logic Controller from the MicroLogix 1200 family. This unit delivers twenty-four 24VDC inputs and sixteen outputs for precise machine control. Engineers use it for micro and small automation applications across many industries. Its robust design supports panel or DIN rail mounting in demanding factory environments.
Product Procurement & Buyer Guide
Procurement managers must evaluate the 1762-L40BXBR against their specific application needs. This controller has a total of 40 I/O channels. The input side features twenty standard 24VDC sink/source channels and four fast 24VDC inputs. The output side includes eight relay outputs, seven 24VDC FET outputs, and one high-speed 24VDC FET output. This mixed configuration supports both high-power and high-speed switching tasks.
You must select this model for applications requiring versatile communication. The 1762-L40BXBR has an embedded 8-pin mini-DIN serial port. It supports protocols including DF1, DH-485, ASCII, and MODBUS. This allows easy connection to HMI panels, SCADA systems, and other intelligent devices. The unit also has two trim potentiometers for adjusting internal registers.
Consider the environmental tolerances for your installation location. The 1762-L40BXBR operates in an ambient temperature range of `+0°C` to `+55°C` (`+32°F` to `+131°F`). It can withstand a maximum operating shock of 30G and vibration of 5G at 10 to 500 Hertz. This ruggedness makes it suitable for harsh industrial settings. The unit weighs only 1.1 kilograms for easy handling.
Step-by-Step User & Installation Guide
Follow these steps to correctly install the 1762-L40BXBR in your control panel. First, choose either panel mounting or DIN rail mounting. The unit dimensions are `90 mm` (height with DIN latch open `104 mm`), `160 mm` (width), and `87 mm` (depth). Ensure your enclosure has sufficient space for the base unit and up to six expansion I/O modules.
For the power supply, connect a dedicated external 24VDC source to the controller. The power supply usage rating is `82 VA`. Remember that the inrush current can reach `25A for 8 ms at 120V AC`. You must use appropriately rated circuit protection. The controller consumes `40 Watts` of power and dissipates `27.9 Watts` of heat.
Next, wire your field devices to the I/O terminals. The input circuit type is 24VDC sink or source. The relay outputs have a contact rating of `24-125VDC` or `120-240VAC`. They can carry a maximum load current of `10A` and withstand `1440VA`. The relay life is rated for `20,000,000` mechanical cycles.
Finally, establish communication with your host system. Connect to the 8-pin mini-DIN serial port using the DF1 protocol. You can also use the separate programming port for configuration. The isolation voltage between input groups and the backplane is 75 Volts DC. This isolation is tested at 1200 Volts AC for 1 second.
