OWT-TC Thermocouple Temperature Signal Isolation Converter (17.5 mm)

The OWT-TC thermocouple temperature signal isolation converter adopts a digital MCU design. The thermocouple input type and temperature range can be changed via configuration software (AT2TC-Utility), offering both the flexibility of digital operation and the convenience of analog operation. It is primarily used for temperature measurement conversion and isolation.

This slim isolation converter provides two isolated signal outputs, and its switching power supply offers ease of installation. It also features power, input, and output indicator lights, as well as pluggable terminals for convenient on-site installation and monitoring of operating status.

Features

The room temperature compensation uses a high-precision temperature IC, ensuring that the room temperature compensation error of the isolation converter is less than ±0.5℃ across the entire operating temperature range.
Optional DIP switch for switching output signals: six standard output signals available: 0-5V/0~10V/1~5V/2~10V/4~20mA/0~20mA. Users can switch between these signals themselves.
100ms high-speed response signal output, suitable for precision temperature control circuits.
Dual-loop outputs are fully isolated, allowing selection of different output signals.
It features power, input, and output LED indicators for easy monitoring of on-site operating status.
The isolation converter is only 17.5mm wide and can be installed on a standard 35mm DIN rail.
