TRANCEL TMT 2140

RTD to ModBus Transmitter  TMT 2140

TRANCEL TML 2140 has been designed to provide a highly reliable isolated connection between (up to four) RTD and PLC through RS-485. Linearizing the measurement signal with extreme accuracy makes it ideal for the most exacting temperature measuring applications. Benefiting from lead resistance compensation and the highest interference resistance, problem-free application is guaranteed with long transfer distances in the harshest environments.
