Technical Specifications

Solving the Discontinued Hardware Crisis

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

The 1747-BA serves a single but mission-critical function: it maintains the RAM contents of the SLC 500 processor during power loss. Without a functional battery, a power interruption — planned or unplanned — results in complete program loss. On processors without a backup EEPROM module, or where the EEPROM has not been updated to reflect the current ladder logic revision, this means the machine cannot restart without a programmer and the original program file. In facilities where documentation practices have lapsed over decades of operation, that program file may no longer exist in a recoverable form.

The consequence is not a maintenance event. It is a production stoppage of indeterminate length, followed by either emergency re-engineering or forced capital expenditure on a platform migration that was not budgeted, not planned, and not timed to production schedules.

How to extend your SLC 500 asset life by 5 to 10 years at minimal cost:

This is not a complex strategy. It is disciplined asset management applied to a platform that, despite its age, continues to perform reliably when maintained. The cost of the above measures is measured in hundreds of dollars. The cost of ignoring them is measured in production days.

Condition & Reliability Assurance

DriveKNMS applies a 5-step quality assurance process to all discontinued components before dispatch review:

Key Features for System Maintenance

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Can I use a third-party equivalent battery?
Third-party equivalents exist. Before installation, verify that the replacement matches the OEM specifications for voltage, capacity, and physical form factor. Incorrect substitutions can damage the processor or fail to maintain memory during the rated interval. DriveKNMS supplies only parts that have been verified against the OEM specification.
