• NTC to dc 4-20mA Signal Converter
  • 10K NTC to Analog Signal Converter

DIN Rail 10K NTC to DC Signal Converter


This NTC to voltage signal converter module can coverts 100K 10K NTC thermistor signal into 0-5V or 0-10V signal in linearity. 0.1% high accuracy linear conversion. Standard 35mm DIN Rail-mounted shell, convenient to use in industrial applications.

Main Features
● 10K B3435 B3950 NTC thermistor signal input.
● Standard 0-10VDC, 0-5V, 4-20mA output.
● 24VDC power supply, have protection circuit.
● 0.1% high accuracy, high linear signal conversion
● 1500VDC isolated operating power supply.

BRT NTC-AD NTC Thermistor to voltage converter accepts 10k NTC signal input, and converts it into 0-10V 0-5V 4-20mA, etc. in linearity. The NTC thermistor signal is processed by internal modulation circuit to output temperature (voltage) signal. It is in small size, low cost, easy-to-use, and provides a simplified solution in temperature measuring applications.

Main Applications
● NTC thermistor sensor signal remote transmission.
● Industrial automatic temperature controlling system.
● Boiler equipment over-heating protection system.
● Temperature signal data acquisition and monitoring.
