The Allen‑Bradley 1762‑L40AWAR is a capable MicroLogix 1200 series programmable logic controller designed for flexible automation solutions. This controller provides 40 embedded I/O channels, combining 24 AC inputs and 16 relay outputs in a single compact housing. Its 120/240V AC power supply ensures compatibility with global electrical systems. The 1762‑L40AWAR distinguishes itself with dual serial ports, offering enhanced connectivity for programming and communication. Manufacturing facilities, packaging lines, and material handling systems commonly deploy this reliable controller.
The 1762‑L40AWAR delivers consistent performance across diverse industrial environments. Its input circuit operates at 120 Volts AC , while the output circuit uses relay contacts rated for 24‑125VDC and 120‑240VAC . The relay outputs handle a load current of 10A minimum and endure up to 20 million mechanical cycles .
Input Details
For inputs 0 through 3, the on‑state voltage ranges from 14 to 24 Volts DC , while inputs 4 and above require 10 to 24 Volts DC . The off‑state voltage stays between 0 and 5 Volts DC , and the minimum off‑state leakage current is 1.5 mA . This design ensures reliable signal detection from sensors and switches. The inputs support both sink and source wiring configurations, offering installation flexibility.
Power Supply
The controller draws 82 VA of power and accepts an input frequency of 47 to 63 Hertz . Inrush current reaches 25A for 8 ms at 120V AC and 40A for 4 ms at 240V AC . Therefore, users should size circuit breakers accordingly to avoid nuisance tripping. The unit can control loads up to 1440 VA .
The 1762‑L40AWAR includes two 8‑pin mini‑DIN serial ports . One serves as a dedicated programming port for exclusive configuration and program downloads. The other functions as a general‑purpose communication port, also usable for programming. Both ports support DF1 , DH‑485 , ASCII , and Modbus protocols (master and slave modes).
Consequently, you can connect this PLC to a wide range of devices. Modbus support enables direct integration with power meters, smart relays, and switches without requiring converters or gateways. ASCII protocol proves particularly useful for interfacing barcode scanners commonly found in production and manufacturing industries. The ports use the standard 8‑pin mini‑DIN circular interface, compatible with Allen‑Bradley 1761‑CBL‑PM02 cables or custom‑fabricated alternatives.
The 1762‑L40AWAR measures 90 mm in height (104 mm with DIN latch open), 160 mm in width , and 87 mm in depth . It operates within an ambient temperature range of 0 to 55 degrees Celsius . Installation requires an enclosure that provides adequate protection according to the installation area. Climate control devices may be added to maintain the designed operating temperature. Shipping weight is 2.4 pounds , making handling and installation straightforward.
Proper installation ensures reliable operation and long service life. First, mount the controller on a DIN rail or panel within a suitable enclosure. Next, connect the AC power supply to the designated terminals, observing proper grounding practices. Then, wire input devices such as push buttons, limit switches, and proximity sensors to the input terminals. Connect output loads such as contactors, solenoids, and indicator lights to the relay output terminals.
Furthermore, pay close attention to the current per group common rating of 8 Amps . Exceeding this limit may damage the 1762‑L40AWAR or connected equipment. Therefore, distribute loads evenly across output groups. Additionally, use proper fusing or circuit protection for each output circuit. Finally, connect programming and communication cables to the appropriate 8‑pin mini‑DIN ports and configure protocol settings in your software.

Q1: What is the difference between the 1762‑L40AWA and 1762‑L40AWAR?
The 1762‑L40AWAR includes a dedicated programming port in addition to the communication port, whereas the 1762‑L40AWA has only one communication port. Both controllers share the same I/O configuration and power supply.
Q2: What software is required to program the 1762‑L40AWAR?
Rockwell Automation's RSLogix 500 or CCW (Connected Components Workbench) software is used to program the 1762‑L40AWAR . Both support ladder logic programming and online monitoring.
Q3: Can the 1762‑L40AWAR communicate with a third‑party HMI?
Yes, the 1762‑L40AWAR supports Modbus and DF1 protocols over its serial ports. Therefore, it can communicate with most HMIs that support these protocols.
Q4: What is the maximum output load current per point?
Each relay output can handle up to 10A minimum at 24‑125VDC or 120‑240VAC. However, the total current per group common must not exceed 8 Amps .
Q5: Does the controller retain its program during a power loss?
Yes, the 1762‑L40AWAR uses non‑volatile EEPROM memory to retain the user program. No battery backup is required for program retention.
