The AB 1747-L524 is a modular PLC processor with 4K words of memory and a DH-485 communication interface. It is intended for a compatible 1746 chassis installation with separate power and I/O hardware. Its communication port must be matched to the correct programming interface and cable; connector appearance alone does not establish compatibility. A replacement inquiry should include the processor label, operating system information, original project and chassis arrangement. Confirm the battery and any optional EEPROM module as part of the offered package.

Supply and Quotation

Request a quotation for AB 1747-L524 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

Check processor revision, program requirements, 1746 chassis and DH-485 connection. Use a supported DH-485 interface; do not treat the communication connector as Ethernet.

FAQ

Q1. Is the front communication connector an Ethernet port?

No. This processor communicates over DH-485. Use the correct interface and cable for that network.

Q2. Does 1747-L524 have a direct RS-232 port?

No built-in RS-232 port is provided. Programming access requires a compatible DH-485 communication arrangement.

Q3. What memory capacity should be listed?

Use 4K words. Check the original project and optional backup module before selecting a replacement.

Q4. How can I request a quotation for 1747-L524?

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.
