HE693RTD601

Horner Electric's HE693RTD601 serves as a resistance temperature module designed for precise temperature measurements. This unit accommodates six separate input channels, allowing for simultaneous monitoring of multiple RTD sensors. Power consumption has been measured at 75 mA under a 5V DC supply, making it energy-efficient for various implementations.

The input impedance of the module is greater than 1000 Megohms, enabling it to connect effectively with high-resistance sensors without substantial signal loss. An integrated A/D conversion approach featuring 16 bits enhances measurement accuracy, ensuring reliable data gathering across channels. This module achieves a rapid update time of 50 channels per second, essential for environments where temperature measurements need to be taken frequently.

For RTD applications utilizing PT-100 sensors, the average current is recorded at 330 microamps, allowing for effective performance under standard operating conditions. Channel-to-channel tracking is maintained within 0.1°C, ensuring consistency and precision among multiple channels. The module offers multiple resolution options, including 0.5 degrees Celsius or Fahrenheit, 0.125 degrees Celsius, and 0.1 degrees Celsius or Fahrenheit, providing flexibility based on application requirements.

This device operates efficiently in an ambient temperature range from 0 to 60°C (32°F to 140°F) and is capable of functioning in environments with relative humidity ranging from 5% to 95% without condensation. The module's durability is further fortified with a fault protection device in the form of a Zener diode clamp, ensuring it remains operational under adverse conditions.
