Key features

E series 16-bit high-precision classic model, with higher precision than 16E series

Integrated AI/AO/DIO/counter full functions, suitable for precise low-speed measurement and control

Common in old laboratories / industrial test benches, with good stability

Complete hardware triggering, external clock, overvoltage protection Applicable scenarios

High-precision low-speed analog signal acquisition (sensors, strain bridges, thermocouples)

Maintenance and replacement of old equipment, maintenance of traditional measurement and control systems

Situations requiring 16-bit accuracy but without the need for high-speed sampling Notes for Attention

Only the old-style PCI slots are available. The new motherboard (all PCI-E) cannot be installed.

The old version of the NI-DAQ driver must be used. It does not support the new system and DAQmx.

There is no electrical isolation. An additional isolation module is required in a strong interference environment.

Direct replacement model

Same function upgrade: PCI-6221 (M series, DAQmx)

PCIe replacement: PCIe-6321, PCIe-6341 (X series)
