1762-L40BWAR 40-Point Controller | Allen-Bradley

Allen-Bradley 1762-L40BWAR MicroLogix 1200 Programmable Controller

Power Supply and Electrical Characteristics

• The Allen-Bradley 1762-L40BWAR operates on an input power of 120 to 240 Volts AC at a frequency of 47 to 63 Hertz.
• It features a power supply usage of 82 VA and dissipates 22 Watts of heat during normal operation.
• This controller handles inrush current of 25 Amps for 8 ms at 120V AC and 40 Amps for 4 ms at 240V AC.
• The internal power supply provides 600 mA at 5VDC and 500 mA at 24VDC, with sensor power up to 400 mA at 24VDC.
• Note that the 24VDC sensor power source is internally connected to chassis ground and should not power output circuits.

Input and Output Specifications

• The 1762-L40BWAR includes twenty standard 24VDC inputs and four fast 24VDC inputs, supporting sink/source wiring configurations.
• Fast inputs reside on channels 0-3, while standard inputs occupy channels 4 and above for easy identification.
• It features sixteen relay outputs with a contact rating of 24-125VDC and 120-240VAC, handling a minimum load current of 10A.
• These relay outputs offer a mechanical life of 20,000,000 cycles, ensuring long-term reliability for switching tasks.

Dual Communication Ports and Protocols

• The MicroLogix 1200 1762-L40BWAR features two 8-pin mini-DIN communication ports for flexible connectivity.
• Use the front panel port as the primary interface for HMI, SCADA, or programming workstation communication.
• The left-side programming port allows simultaneous controller programming and online edits without disconnecting the primary port.
• Both ports support DF1, DH-485, ASCII, and MODBUS protocols for versatile network integration.

Mechanical Specifications and Environmental Tolerance

• You can mount the 1762-L40BWAR on a DIN rail or panel, with dimensions of 160 mm width, 87 mm depth, and 90 mm height (104 mm with DIN latch open).
• It operates reliably in ambient temperatures from 0 to 55 degrees Celsius, requiring a protective enclosure.
• For storage, keep this unit in environments ranging from -40 to 85 degrees Celsius to maintain integrity.
• The controller holds multiple agency certifications including UL 508, C-UL, Class I Div. 2, CE/RCM/EAC, ensuring compliance with global standards.

Frequently Asked Questions (FAQ)

• What is the difference between standard and fast inputs on the 1762-L40BWAR? Fast inputs on channels 0-3 respond quicker for high-speed counting, while standard inputs on higher channels suit general-purpose sensing.
• Can I use both communication ports at the same time? Yes, the dual ports on the Allen-Bradley 1762-L40BWAR operate simultaneously, allowing programming without removing existing connections.
• What are the relay contact ratings for this controller? The sixteen relay outputs handle 24-125VDC and 120-240VAC loads with a minimum current of 10A.
• Does the 1762-L40BWAR provide power to sensors? Yes, it supplies up to 400 mA at 24VDC for sensors, but do not use this source to power output circuits.
• What is your return policy for this PLC? We accept returns within 30 days if the item remains in its original, unused condition.
