Description
BRT NTC-D1 DIN Rail NTC Thermistor signal converter is designed to convert 10K 100K NTC signal into 0-10V 0-5V 4-20mA standard current voltage signal in linearity. The NTC thermistor signal is processed by internal modulation circuits and isolation circuits. Its input, output and power supply terminals are isolated. Its conversion accuracy is 0.2%. Standard 35mm DIN Rail shell, easy to install in industrial site.
Main Features
● High linear conversion, low error output.
● Typical accuracy is 0.2%.
● 1-channel NTC signal input, 1-channel dc current or voltage signal output.
● 24VDC standard operation power supply.
● Standard 0-5V, 0-10V, 4-20mA, 0-20mA signal output.
● 1500V isolation between power terminals and signal I/O terminals.
● Small size 35mm DIN rail-mounting shell, save space and cost.
Typical Applications
● NTC thermistor sensor signal data acquisition.
● Temperature signal transmission and conversion.
● Industrial site temperature signal monitoring.
