The AB 1762-L40BWAR is an AC-powered PLC with twenty-four 24V DC inputs and sixteen relay outputs. Four inputs support fast input functions. The R suffix identifies an additional Programmer/HMI serial port, which allows a local programming or operator interface connection alongside Channel 0. That extra port has fixed DF1 Full-duplex behavior and cannot initiate messages. Check the original wiring, terminal allocation and serial arrangement before replacing the controller. Confirm any expansion modules, cables and software requirements with the quotation.

Supply and Quotation

Request a quotation for AB 1762-L40BWAR with quantity, destination and preferred condition. Send the installed unit label and required firmware information. We will confirm availability, included parts, inspection scope, delivery terms and warranty for the specific offer. Programming software, machine projects and optional system components require separate confirmation.

Compatibility

Match the complete BWAR suffix, AC supply, DC input wiring and relay loads. Confirm that the additional fixed-function serial port suits the installed HMI or programming connection.

FAQ

Q1. What does the final R indicate on 1762-L40BWAR?

It identifies the additional Programmer/HMI serial port. A model without this suffix does not provide the same extra connection.

Q2. Are the inputs powered at the same voltage as the PLC supply?

The PLC uses nominal 120/240V AC power, while its twenty-four digital inputs are 24V DC. Check these circuits separately.

Q3. Can the extra serial port operate as a Modbus master?

No. The Programmer/HMI port supports fixed DF1 Full-duplex response operation only. Other supported protocol functions use Channel 0.

Q4. How can I request a quotation for 1762-L40BWAR?

Send the complete model, quantity, preferred condition and destination. Include the hardware series and firmware if matching an installed unit. Price and availability are confirmed in the offer.

Q5. Does the supply include the machine program or software license?

Hardware supply does not automatically include application files, passwords or software licenses. Confirm access to the original project and compatible engineering software before replacement.

Q6. What inspection information can be requested?

Request clear label and connector photos, firmware identification and an agreed power-up or communication check where applicable. Confirm accessories, packaging, dispatch timing and warranty before shipment.
