Description.

The TW-DA is designed primarily for low cost digital to analogue conversions for PLCs, controllers, etc. Digital inputs
are converted in binary to analogue V or mA outputs.

TW-DA Digital to
Analogue Converter.

Isolated Parallel Digital

Input to  Three Wire V or mA

Analogue Output Converter.

Quality Assurance Programme.

The modern technology and strict procedures of the ISO9001 Quality Assurance Programme applied during design,
development, production and final inspection grant the long term reliability of the instrument.
