604A: Data Acquisition Signal Interface

request a quote

The 604A data acquisition interface was designed to enable physiology researchers to easily interface a Dual-Mode muscle lever, force transducer, high-speed length controller and stimulator to a National Instruments PC-based A/D card. The 604A Interface consists of a 1U (1.75”) high, 19” wide, rack-mount case with BNC connectors on the front and a ribbon cable connector on the back. Each interface includes six BNC patch cables, six BNC terminators and one BNC T-fitting. The front-panel connections are separated into 3 main groups: A/D inputs, D/A outputs and digital I/O.

All models in the series have eight (8) analog-to-digital (A/D) inputs , connected in a differential mode. The 604A has two (2) digital-to-analog (D/A) outputs while the models 604D and 604E have four (4) digital-to-analog outputs.

The 604A A has six (6) digital input/output (Digital I/O) connectors, the 604E has four (4) Digital I/O connectors and the 604D has twelve (12) Digital I/O connectors.

The Stimulator connection is used to connect the A/D software to an external stimulator. Depending on the stimulator being used, the output from the Stimulator connector may simply trigger the stimulator to perform a pre-set stimulation routine or our ASI software programs can be used to control pulse width, pulse frequency, frequency duration, train, train frequency, and train duration.

  • interfaces with Aurora Scientific force transducers, length controllers, muscle levers and stimulator.
  • connects to PC via National Instruments A/D card

  • includes BNC cables, terminators (50 Ohm) and T-fitting
  • eight A/D inputs: accepts analog signals in range of -10 to +10 V
  • two D/A outputs: generates analog voltages in range of -10 to +10V
  • six digital I/O connectors: triggers external devices, stimulator
