NI PXI-4220 Module

Core Performance & Industrial Application

The NI PXI-4220 (778745-4220) is a 2-channel, 16-bit PXI strain/bridge input module for quarter-, half- and full-bridge sensors such as strain gages, load cells and pressure transducers.

Per-channel bridge configuration, excitation, gain and filter fully programmable; simultaneous sample-and-hold removes inter-channel phase delay; 9-pin D-SUB per channel.

Programmable shunt and zero calibration circuitry cancels gain/offset error; voltage ranges from ±10 mV to ±10 V; max sample rate 333 kS/s.

It acquires load/force/strain signals in PXI test and measurement systems.
