Product Description:
The 7AT664.70-1 by B&R is a sophisticated 4-channel temperature module designed for high-precision thermal monitoring. This module is activated by selecting a sensor type in configuration word 14, which is applied to all channels. With a 16 Bit digital converter resolution, it is tailored for use with thermocouples, ensuring accurate and reliable temperature measurements. The module offers a maximum temperature drift per degrees C of +/- (1.7 uV + 0.0001 * U?), where U? represents the thermal voltage in microvolts, highlighting its exceptional stability. Additionally, it boasts a terminal temperature error of +/-1 degrees C after 10 minutes, which ensures consistent performance in varying environmental conditions.
One of the key features of the 7AT664.70-1 is its automatic conversion of measurement values to temperature values within the module, simplifying the data processing for users. The module has a maximum power consumption of 0.4 W, making it energy efficient. However, it does not provide electrical isolation between the input and the PCC, nor between inputs, which should be considered when integrating it into systems requiring isolation. The operating modes are versatile, supporting sensor types J, K, and S with terminal temperature compensation, making them adaptable for different thermocouple applications. The raw value is quantized to 2 uV within a voltage range of +65.534 mV, excluding terminal temperature compensation.
The terminal temperature can be manually entered for each channel to facilitate terminal temperature compensation, offering flexibility and precision in various application scenarios. This level of customization and precision makes the 7AT664.70-1 an invaluable asset for professionals requiring accurate temperature monitoring. Its inclusion in the B&R series underscores its quality and performance, providing a reliable solution for industrial automation and control systems.
