The National Instruments FD-11603 is a high-performance Voltage Input Device designed for use with its FieldDAQ data acquisition systems. This robust module, identified by part number 785639-01, features eight analog input channels with a resolution of 24 bits, allowing for precise voltage measurements in the range of ±10.5 V. The FD-11603 can be programmed using the NI-DAQmx driver tool and supports synchronization across multiple FieldDAQ devices, making it ideal for complex measurement setups in outdoor environments.

With an exceptional sampling rate of ±100 kS/s per channel, the FD-11603 enhances data acquisition capabilities while ensuring channel-to-channel isolation to eliminate ground loops and protect against transient voltages. The device operates autonomously without requiring additional power supplies, relying instead on a standard 24 VDC source. Designed with a maximum ingress protection rating of IP67, the FD-11603 is dustproof and water-resistant, suitable for harsh conditions. It also incorporates features such as an integrated network switch for compatibility with TSN modules and built-in circuitry for daisy-chaining, which streamlines integration within existing systems. The device is ruggedized to withstand shock levels of up to 100 g and vibration levels of 10 g, ensuring reliability in dynamic environments. The dimensions are compact at 7.8 in. × 3.0 in. × 1.9 in., weighing 2 lb 10 oz. This module is backed by a 2-3 year warranty, and detailed documentation is available for download.
