Product Overview

The National Instruments GPIB-120A is a GPIB expander / isolator. The IEEE 488.1 standard prescribes a maximum of 15 electrical device interface loads in a GPI system. The National Instruments GPIB-120A increases the maximum number of GPIB system devices from 15 to 28. The GPIB-120A is also useful in test and measurement systems because it provides an electrically isolated interface to one or more devices. The GPIB-120A is software transparent; you do not need to rewrite your application software.

Features of the NI GPIB-120A include:

  • Expands the number of GPIB devices to 28
  • Bidirectional expansion - Controllers, Talkers, and Listeners can exist on either side of the expansion
  • 400 Vrms electrical isolation between GPIB systems for 1 minute
  • Software transparent – no software modifications required
  • Signal buffering extends the maximum GPIB cable limit to 40 m (device load every 2 m of bus cable)
  • Built-in 120 or 240 VAC power supply
  • Meets FCC Class A electromagnetic noise emission requirements
  • UL listed
