LAB-PC-1200

National Instruments ISA Bus Multifunction DAQ Board (Legacy)

General Description

Part Number

• Model: LAB-PC-1200

• Variant: LAB-PC-1200AI (no analog outputs)

Key Specifications

• Bus Interface: ISA (16-bit), legacy PC/AT only

• Analog Input (AI):

  • 8 single-ended / 4 differential channels

  • Resolution: 12-bit (0–4095)

  • Max sampling rate: 100 kS/s (single-channel)

  • Input ranges: Software-selectable 0–10 V (unipolar) or ±5 V (bipolar)

  • Programmable gain: 1, 2, 5, 10, 20, 50, 100

• Analog Output (AO):

  • 2 channels, 12-bit DACs

  • Ranges: 0–10 V (unipolar) or ±5 V (bipolar)

• Digital I/O (DIO): 24 lines (TTL-compatible)

• Counter/Timers: 3 × 16-bit, 8 MHz (8253-compatible)

• I/O Connector: 50-pin header

• Power: ISA bus-powered

• OS Support: Legacy Windows (95/98/XP), DOS

• Driver: Traditional NI-DAQ (v4.9 or older)

Main Features

• All-in-one: AI + AO + DIO + counters for basic DAQ systems

• Low-cost entry-level board for labs and small industrial setups

• Software-configurable ranges/gain; no DIP switches for I/O ranges

• Digital triggering for synchronized data acquisition

• Compact ISA card form factor for legacy desktops

Applications

• Laboratory data logging and sensor monitoring

• Small-scale industrial process control and automation

• Educational and research test setups

• Legacy system maintenance (ISA-based PCs only)

Replacement Notes

• ISA bus obsolete: No modern PCs support ISA; replaced by PCI, USB, Ethernet DAQ devices.

• Recommended replacements: USB-6001/6002, PCIe-6221, or USB-6341 (modern NI DAQ with similar I/O count, software-compatible via NI-DAQmx)。
