Description

The 16-Channel BF card is a daughter card in the P4 range with 16 independent channels and a 16-bit ADC resolution. It is designed for temperature and strain measurements in structural monitoring and industrial control applications.

Compatible with a wide range of sensors (K, J, T thermocouples, 2/3/4-wire RTDs Pt100/Pt1000, strain gauges), it provides a programmable current source from 50 µA to 1.5 mA per channel, as well as a 50/60 Hz rejection filter for accurate measurements in industrial environments.

With an acquisition frequency of 2 kSPS per channel and a ±2.5V differential input voltage, this card benefits from the P4 platform's microsecond GPS synchronization to ensure temporal coherence of multi-point measurements.
