This unit provides robust communication via an embedded serial port. It supports DF1, DH-485, and MODBUS protocols for flexible integration. This model is ideal for demanding industrial automation tasks.
Expert Technical Evaluation & Performance Review
This Allen-Bradley MicroLogix 1200 controller delivers reliable performance. The 1762-L40AWAR uses a 120-240V AC power supply. It consumes 82 VA during normal operation. The inrush current reaches 25A for 8 ms at 120V AC. At 240V AC, the inrush current is 40A for 4 ms. This unit controls loads up to 1440 VA efficiently.
The 1762-L40AWAR features 24 discrete inputs. Inputs 0 through 3 require an ON state voltage of 14 to 24V DC. Inputs 4 and higher need an ON state voltage of 10 to 24V DC. The OFF state voltage range is 0 to 5V DC. The OFF state leakage current is a minimum of 1.5 mA. These precise thresholds ensure reliable signal detection.

The 16 relay outputs provide robust switching capabilities. Each relay contact handles loads from 24-125VDC and 120-240VAC. The contacts support a minimum load current of 10A. Each relay endures 20,000,000 mechanical cycles. This ensures a long operational lifespan for your machinery.
The communication interface uses an 8-pin mini-DIN serial port. This port supports RS232 standards for DF1 and DH-485 protocols. The unit also supports MODBUS Master/Slave and ASCII protocols. This allows direct connection to smart relays and barcode scanners. You do not need an extra converter for MODBUS devices.
The operating temperature range is 0 to 55 degrees Celsius. The unit dimensions are 90 mm high, 160 mm wide, and 87 mm deep. The shipping weight is 2.4 pounds. You must install this PLC in a suitable enclosure. Climate control may be necessary to maintain the proper temperature.
Product Procurement & Buyer Guide

Procurement managers should verify the power supply requirements first. The 1762-L40AWAR needs a 120-240V AC input source. This model provides 24 inputs and 16 relay outputs. This I/O count suits medium-sized control applications. The relay outputs simplify wiring for high-voltage AC loads.
Application engineers will value the multiple communication protocol support. The DF1 and DH-485 protocols enable seamless integration with existing networks. The MODBUS support allows direct linking to power meters and smart relays. The ASCII protocol connects easily to barcode scanners. This reduces the need for additional communication modules.
The 1762-L40AWAR has a dedicated programming port. You use this port exclusively for configuration and program downloads. The main communication port also serves as a programming interface. You can use an Allen-Bradley 1761-CBL-PM02 cable for connections. This dual-port design simplifies setup and maintenance tasks.
This controller supports limited expansion capabilities. However, the embedded I/O handles many standard applications. The 24 sink/source inputs offer flexible wiring configurations. The 16 volt-free relay outputs provide galvanic isolation. This design protects your control system from electrical noise.

The relay contact ratings are critical for load selection. Each output handles a minimum of 10A. The mechanical life of 20,000,000 cycles ensures long-term reliability. This makes the unit suitable for high-cycle applications. You can control motors, solenoids, and contactors directly.
