National Instruments 785854-01 Temperature Input Device for FieldDAQ
Part Number 785854-01 identifies the National Instruments FD-11614 Temperature Input Device for FieldDAQ. The 785854-01 features 16 isolated thermocouple channels and 4 CJC (Cold Junction Compensation) channels with galvanic isolation between the channels and the chassis. Likewise, the device has a Delta-sigma ADC with a resolution of 24 bits. The sample mode is simultaneous and the sample rate can be configured by the user. The timebase frequency can be configured to 80 MHz, 20 MHz, or 100 kHz. The voltage measurement range is ±78.125 mV while it can measure temperature ranges defined by NIST (J, K, T, E, N, B, R, and S thermocouple types).
This 785854-01 supports TCP/IP and UDP protocols, using a variety of network ports: HTTP:80 (configuration only), TCP:3580; UDP:5353 (configuration only), TCP:5353 (configuration only); TCP:31415; UDP:7865 (configuration only), and UDP:8473 (configuration only). It has a default MTU size of 1500 bytes. Additionally, it has two internally-switched 8-pin X-coded M12 ports for Ethernet communication. The communication rates are auto-negotiated between 10/100/1000 Mbps. The maximum cabling distance is 100 meters per segment, with a maximum of 15 hops per line. Furthermore, it uses IEEE 802.1AS protocol for network synchronization over 1000 Base-TX interface.
The 785854-01 supports an input voltage range of 9 VDC to 30 VDC, with a maximum power consumption of 5.7 W. Both power input and output use a 5-pin L-coded male M12 connector. The recommended torque for M12 connectors is 0.6 Nm. The maximum current for the Power IN/OUT terminals is 10 A, and a 16 A slow blow fuse is suggested for external overcurrent protection.
In terms of physical dimensions, the 785854-01 measures 7.8 in. × 3.0 in. × 1.9 in. and weighs 1.18 kg. It has a recommended calibration interval of 1 year. The device is designed to operate between -40 °C to 85 °C with relative humidity up to 100%. It can be stored in temperatures ranging from -40 °C to 100 °C. It is designed for operation at altitudes up to 5000 meters.
