The Horner Electric HE693THM449 is an input module tailored for thermocouple use, featuring four channels for flexible sensor connectivity. It accommodates a variety of thermocouple types, including J, K, N, T, E, R, and S, each catering to specific temperature ranges for accurate calculations.
With a resolution of 0.5°C and a typical accuracy of ±0.5°C, particularly for Type J thermocouples, the module ensures precise temperature readings. In terms of electrical characteristics, the HE693THM449 provides robust isolation of 1000VDC between channels and the bus, contributing to operational integrity in potentially hostile electrical environments.
The module can function within an operational temperature range of 0 to 60 °C. It also withstands storage conditions from -40 to 85 °C with a humidity tolerance of 5% to 95% without condensation. Input impedance exceeds 20MΩ, and the maximum safe overload is rated at ±35V, ensuring protection against input voltage variations. The power requirements include 70mA at 5VDC and 60mA at 24V relay, making it efficient for integration within control systems.
