SANSHO FPBA RECHARGEABLE Replacement/Upgrade Solution

Product Overview

SANSHO FPBA RECHARGEABLE Replacement/Upgrade Solution: Seamless Transition for FP Series Control Systems

When your SANSHO FP series PLC installation depends on reliable backup power to retain program memory and maintain real-time clock data during power interruptions, the FPBA RECHARGEABLE Li-Ion Battery Module is the direct, field-proven replacement. Whether you are migrating from an aging SANSHO FP0 or FP-e controller, retiring a legacy SANSHO FP1 or FP2 rack-based system, or simply replacing a degraded battery in an active production line, this module delivers a smooth, low-risk upgrade path with no firmware changes and no re-programming required.

The FPBA RECHARGEABLE is engineered to fit the original battery compartment of SANSHO FP series compact PLCs without mechanical modification. Its Li-Ion chemistry provides a longer service life and more stable voltage curve compared to older Ni-Cd or alkaline backup cells, reducing the frequency of planned maintenance shutdowns. For facilities managing multiple SANSHO FP0R, FP-Sigma, or FP-X controllers across a production floor, standardizing on the FPBA RECHARGEABLE simplifies spare-parts inventory and ensures consistent backup performance across all nodes.

Seamless Upgrade Solutions

A battery replacement is rarely an isolated task on a live production system. In practice, technicians performing an FPBA RECHARGEABLE swap often take the opportunity to audit adjacent components and address deferred maintenance items in the same maintenance window. During a typical SANSHO FP series battery replacement, the following components are commonly inspected or replaced alongside the FPBA RECHARGEABLE:

The SANSHO FP0R-C32T CPU unit is the most common host controller for the FPBA RECHARGEABLE in compact automation cells. If the CPU itself is approaching end-of-life or showing intermittent faults, replacing it in the same window eliminates a second planned shutdown. For systems using expansion I/O, the SANSHO FP0R-E16T expansion I/O module is a frequent companion replacement — its terminal block wiring is identical to the base unit, so no re-labeling is required. Where the control system communicates over RS-485 to SCADA or HMI, the SANSHO AFP8550 RS-232C/RS-485 communication adapter should be verified for firmware compatibility with the replacement CPU before the maintenance window closes.

For installations that include a SANSHO GT series HMI panel connected via MEWTOCOL-COM, the battery swap is a good time to verify the HMI communication parameters and update the screen program if the CPU firmware has been revised. In rack-based FP2 installations, the SANSHO FP2-PS2 power supply module should be load-tested during the same window, as power supply degradation is a common co-failure mode with battery depletion. If the system uses a SANSHO FP2-C1D CPU module in a multi-slot backplane, confirm that the backplane bus connectors are clean and seated correctly after the battery is replaced, as vibration over time can cause intermittent backplane faults that mimic battery-related memory loss.

For sites migrating from older FP1 installations to FP-X or FP-Sigma platforms, the FPBA RECHARGEABLE is compatible across the migration path, meaning the same spare-parts SKU covers both the legacy and the new platform during the transition period. A SANSHO USB programming cable (AFP8513) is recommended on-site during any battery swap to allow immediate program upload verification after power restoration. Signal isolators such as the SANSHO AFP1431 analog input module or third-party DIN-rail signal conditioners should also be checked for calibration drift if the system experienced an uncontrolled power loss prior to the battery replacement.

Retrofit Guidance FAQ

Q: Do I need to rewrite or re-download the PLC program after replacing the FPBA RECHARGEABLE?
A: If the battery is replaced before the CPU loses power (i.e., the CPU remains powered during the swap), program memory is retained. If the CPU was powered down with a fully depleted battery, the program may be lost and must be re-downloaded from a backup. Always maintain an offline program backup on a PC running FPWIN Pro or FPWIN GR before performing any battery maintenance.

Q: Is the FPBA RECHARGEABLE compatible with both FP0 and FP0R controllers?
A: Yes. The FPBA RECHARGEABLE is designed for the SANSHO FP series battery bay and is compatible with FP0, FP0R, FP-e, FP-Sigma, and FP-X compact controllers. Verify the battery bay connector type on your specific unit before installation.

Q: Will replacing the battery affect my RS-485 or MEWTOCOL communication settings?
A: No. The FPBA RECHARGEABLE is a passive power component. Communication parameters stored in non-volatile memory (EEPROM) are not affected by battery replacement. However, if the CPU lost power with a depleted battery, verify communication settings after program restoration.

Q: Can I install the FPBA RECHARGEABLE without removing the CPU from the control cabinet?
A: In most FP compact installations, the battery compartment is accessible from the front panel without removing the CPU from the DIN rail. Refer to the SANSHO FP series hardware manual for your specific model. Ensure the CPU is powered down and the program is backed up before opening the battery compartment.

Q: What is the expected service life of the FPBA RECHARGEABLE compared to the original battery?
A: Li-Ion chemistry typically provides a longer calendar life and more stable voltage retention than the original Ni-Cd cells. Actual service life depends on ambient temperature, charge cycles, and storage conditions. TOPNLMS recommends a preventive replacement interval of 3–5 years under normal industrial operating conditions.
