Overview of the Replacement Relationship Between FTC968(Z) and FTI26
FTI26 is the only replacement model for FTC968, and this is the conclusion that needs to be confirmed first during current selection. Since both FTC968 and FTC968Z have been discontinued, and the original manufacturer's official website does not clearly indicate the replacement relationship of FTI26, many customers spend a lot of time repeatedly confirming during replacement.
The core limitation lies in the power supply method: FTI26 only supports 24VDC DC power supply. Therefore, only the DC-type FTC968 can be directly replaced by FTI26; there is currently no corresponding replacement solution for the AC-type FTC968(Z).
Judgment of Replacement Feasibility
Cases Where Direct Replacement Is Possible
- The original instrument is an FTC968 with 24VDC DC power supply
- The installation interface and process connection are consistent
- The output signal and accuracy requirements are the same as the original model
Cases Where Replacement Is Not Possible
- The original instrument is an FTC968 or FTC968Z with AC power supply
- Only AC power is available on site and cannot be converted to 24VDC
- The electrical characteristics of the original AC model need to be fully replicated
Replacement Decision Comparison Table
| Original Model | Power Supply Method | Can FTI26 Replace It | Remarks |
|---|---|---|---|
| FTC968 | 24VDC | Yes | Direct replacement, confirm interface consistency |
| FTC968 | AC | No | Power supply modification or another solution is required |
| FTC968Z | AC | No | No corresponding replacement model |

Working Principle Comparison
FTI26 Working Principle
FTI26 uses a 24VDC DC power supply. Its working principle diagram is as follows, which can be used to confirm whether the signal processing and output logic meet on-site requirements.
FTC968 Working Principle
The working principle diagram of FTC968 is as follows. Comparing it with FTI26 can help determine electrical compatibility.
Selection and Replacement Recommendations
- Confirm whether the original instrument model is FTC968 or FTC968Z.
- Check the on-site power supply: if it is 24VDC, FTI26 can be selected as a replacement.
- If the power supply is AC, evaluate the feasibility of converting to 24VDC DC, or contact the supplier to confirm other solutions.
- Compare the installation interface, process connection, and output signal to ensure both mechanical and electrical compatibility.
- Before purchasing, it is recommended to request the latest FTI26 sample to confirm parameters and inventory status.
Summary: FTI26 can replace the 24VDC DC-type FTC968, but cannot replace the AC-type FTC968(Z). Confirming the power supply method in advance can significantly reduce selection confirmation time.
