The National Instruments part number 785854-01 designates the FD-11614 Temperature Input Device for FieldDAQ, engineered for precise temperature measurement in industrial applications. This device features 16 isolated thermocouple channels alongside 4 Cold Junction Compensation (CJC) channels, ensuring galvanic isolation between channels and the chassis for enhanced reliability. With a high-accuracy delta-sigma analog-to-digital converter (ADC) boasting a resolution of 24 bits, the FD-11614 supports simultaneous sampling, and its user-configurable sample rates can be set to 80 MHz, 20 MHz, or 100 kHz. It accommodates voltage measurements within a range of ±78.125 mV and is compatible with various NIST-defined thermocouple types, including J, K, T, E, N, B, R, and S.

In terms of connectivity, the device supports TCP/IP and UDP protocols across multiple network ports, including HTTP, TCP, and UDP, with an automatic configuration of communication rates up to 1000 Mbps through two internally-switched 8-pin X-coded M12 ports. The maximum cabling distance is limited to 100 meters per segment and supports up to 15 hops per line, employing the IEEE 802.1AS protocol for effective network synchronization. Power requirements for the FD-11614 range from 9 VDC to 30 VDC, with a maximum power consumption of 5.7 W and a recommended external overcurrent protection using a 16 A slow blow fuse.

Physically, the device measures 7.8 inches by 3.0 inches by 1.9 inches and weighs 1.18 kg, designed for operational environments between -40 °C and 85 °C, with a maximum relative humidity up to 100%. It can also be stored in temperatures ranging from -40 °C to 100 °C and operates effectively at altitudes up to 5000 meters. The recommended calibration interval is one year, ensuring ongoing measurement integrity in demanding field applications.
