Frequently Asked Questions (FAQ)

1. Can the TAmini 485-80020 work as an SSI master alone?

Yes, the TR Electronic TAmini 485-80020 supports pure SSI master operation without any slave.

2. What software do I need to program this display?

Use TRWinProg on Windows via the USB port. You can also program through RS485 with a PC adapter.

3. How do I cascade several slave displays together?

Connect multiple TAmini 485-80020 units using the RS485 bus. Set one as master and others as slaves.

4. Can this model display negative values?

Yes, select the output format “Decimal with sign” in the display parameters.

5. What is the minimum refresh time for fast applications?

The refresh time can go down to 50 ms, suitable for many dynamic positioning tasks.

Application Scenarios

This TR Electronic TAmini 485-80020 fits perfectly in length measuring systems. It works well for cut-to-length machines and linear position feedback. The SSI master mode reads absolute encoders directly. Slave mode shows data from a main controller. Monitor operation listens to SSI traffic without interfering. Many users apply it in packaging lines and woodworking machinery. The compact 96×24 mm front fits small control panels.

Environmental Robustness & Noise Immunity

The 485-80020 uses impact-resistant plastic for light weight and durability. Its IP43 rating protects against small tools and spraying water. The device handles 0°C to +60°C ambient temperatures. RS485 and RS422 interfaces provide good noise rejection. The SSI input supports differential signals for long cable runs. Avoid direct water jets or outdoor installation without an extra enclosure.

Ordering Information
