The National Instruments Part Number 786374-01 is an advanced Voltage Input Device for FieldDAQ, specifically designated as the FD-11601. This device features eight analog input channels with galvanic isolation, ensuring reliable operation within demanding electrical environments. Equipped with a 24-bit Delta-Sigma ADC and analog prefiltering, the FD-11601 provides exceptional accuracy for its input voltage range of ±10.5 V. The device supports a versatile timebase frequency selection encompassing 13.1072 MHz, 12.8 MHz, 12.288 MHz, and 10.24 MHz, maintaining maximum accuracy within ±30 ppm. Sample rates span from 500 samples/s to 102.4 kSamples/s, accommodating various application requirements.

Communication is facilitated through both TCP/IP and UDP protocols, utilizing multiple network ports including TCP:3580 and UDP:7865, with a default MTU size of 1500 bytes. The FD-11601 integrates two internally-switched 8-pin X-coded M12 ports, enabling Ethernet connectivity with negotiated communication rates of 10/100/1000 Mbps, and supports cabling distances of up to 100 meters with a maximum of 15 hops per line. The device operates on a power input range of 9 VDC to 30 VDC, consuming up to 16 W, and features a 5-pin L-coded male M12 for both power input and output. To ensure optimal performance, it is recommended to use a 16 A slow-blow fuse for external overcurrent protection.

Physical dimensions include a compact form factor of 7.8 in. × 3.0 in. × 1.9 in., with a weight of 1.2 kg. The FD-11601 is suitable for operation in extreme environments, offering a temperature range of -40 °C to 85 °C and humidity tolerance of up to 100%. It can be stored in temperatures ranging from -40 °C to 100 °C and is designed to function at altitudes of up to 5000 m. The device requires annual calibration to maintain performance integrity.
