Digital I/O

8 bidirectional 5 V TTL

Timer / Counter

2 24-bit general-purpose counters

Function: Pulse output, frequency / event counting, encoder speed measurement

Interface and mechanical

External connection: 68-pin SCSI-II high-density interface

Board type: Half-long PCI card (shorter than 16XE-10)

Power supply: Direct power from PCI slot

Synchronization: Supports RTSI bus multi-card synchronization

Key features

E series low-cost 16-bit model, high precision but low speed

Half-length card, saves cabinet space, suitable for small industrial control computers

Integrated AI/AO/DIO/counter, complete functions

Good stability, commonly found in old low-speed measurement and control systems Applicable scenarios

Slow high-precision analog acquisition (thermocouple, strain gauge, pressure sensor)

Small automated equipment, simple laboratory measurement and control

Maintenance and replacement for the original E series half-length card system

Caution for use

Only the old PCI slot is available; the new motherboard (full 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

No electrical isolation; additional isolation module is required in strong interference environments

Compatible alternatives

Direct replacement: PCI-6281 (M series, DAQmx)

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