Watanabe TZ-1XA and TZ-5XA DC Signal Isolators
The Watanabe TZ-1XA and TZ-5XA convert a DC voltage or current input into a proportional, isolated DC voltage or current output. Their integrated terminal-block construction provides a compact interface between measurement signals and receiving instruments.
Choose the model according to the available power supply, then specify the required input and output ranges for your application.
Key Features
- DC voltage or current input and output configurations.
- AC-powered TZ-1XA and DC-powered TZ-5XA models.
- Accuracy of ±0.1% of full scale.
- Zero and span adjustment of ±5% of full scale.
- Compact body with integrated wiring terminals.

TZ-5XA Specification and Ordering Information
Use the original reference below to check the DC-powered model’s signal options, dimensions and connections.
Selecting the Right Configuration
- Input: provide the signal type, minimum and maximum values, and details of the source instrument.
- Output: specify what the receiving PLC, indicator, recorder or controller requires.
- Power: confirm whether AC power or a 24 V DC supply is available.
- Load: check the receiving equipment’s input impedance and the selected output’s load limits.
- Response: identify how quickly the signal must follow changes in the process.
- Replacement: send the full existing model code and a photograph of the terminal markings.
