• Backup options: Compatible memory module and real-time clock options
• Programming: RSLogix 500 version matched to processor series

The AB 1764-LSP is the removable processor section of a PLC assembly built around a compatible 1764 base. The base supplies power, field I/O and the Channel 0 serial connection. Consequently, a processor-only purchase does not determine the assembly supply voltage or input and output configuration. For replacement work, provide both the processor reference and the base catalog number. Confirm the processor series, operating system and expansion layout, and identify any memory module, clock or battery required with the offered unit.

Supply and Quotation

Request a quotation for AB 1764-LSP 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 processor series and project to the installed 1764 base. Verify base voltage, I/O type, expansion power budget and communication cable independently.

FAQ

Q1. Is 1764-LSP a complete PLC with power and I/O terminals?

It is the processor module. A compatible 1764 base provides power and field I/O; confirm whether the base is included in the quotation.

Q2. Is it always powered from 24V DC?

The supply depends on the base. The 1764-28BXB is a DC base, while 1764-24AWA and 1764-24BWA are AC-powered bases.

Q3. Does this processor add a second serial port?

No. The assembly uses Channel 0 on the base. The additional processor-mounted Channel 1 belongs to the 1764-LRP variant.

Q4. How can I request a quotation for 1764-LSP?

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.
