Analog & Digital Signal Isolators

Record non-isolated analog or digital signals into ATLAS Neurophysiology System

ATLAS Analog Isolator

Designed for use with:

• ATLAS Acquisition Amplifier
• ATLAS Cart
• MDR-50 Male-to-Male Tether Extension Cable

DESCRIPTION

Input 16 non-isolated experiment signals and record them in parallel with patient signals into the ATLAS Neurophysiology System.


  • Connect other electronic devices to the ATLAS MDR-50 input connectors for research experiment data collection
  • Isolation also prevents any “ground loop” noise
  • User selectable input range for each channel via externally accessible switches
  • Interfaces to ATLAS Amplifier with standard MDR-50 Male-to-Male Tether Extension Cable - included
  • Mounts to the Signal Splitter Rail on the ATLAS Cart - mount included

ATLAS Analog Isolator adds isolation to the ATLAS Combo Board analog inputs: contains precision, isolated amplifiers with outputs separated from inputs by an isolation barrier - allowing user to connect external signals to the ATLAS Combo Board without circumventing the safety mechanisms in the ATLAS Neurophysiology System.


Included / Required for Use:

  • 1 meter MDR-50 Male-to-Male Tether Extension Cable provides the interface between the ATLAS Analog Isolator and the ATLAS Acquisition Amplifier.
    Catalog number: TETH-XTN-MM-1
  • Mounting Bracket

ATLAS TTL Isolator - Digital

Designed for use with:

• ATLAS Acquisition Amplifier

DESCRIPTION

Isolates two 8 bit TTL digital ports in the ATLAS Acquisition Amplifier - allowing users to connect digital experiment signals to the ATLAS Acquisition Amplifier without circumventing the safety mechanisms in the ATLAS Neurophysiology System.


  • Isolate all 4 TTL Ports with two ATLAS TTL Isolators
  • TTL events are synced with the analog data recorded by the ATLAS Acquisition Amplifier
  • Isolator also prevents “ground loop” noise

ATLAS TTL Isolator’s direct connection to the ATLAS Digital I/O Ports provides the isolation barrier, allowing the user to connect external electronic devices with digital I/O signals to the ATLAS Acquisition Amplifier.


Provides an optional configuration of ATLAS Neurophysiology System by isolating two of the four 8 bit TTL Ports on the front of the ATLAS Acquisition Amplifier.


Two ATLAS TTL Isolators provide isolation on ALL four 8 bit TTL Ports when needed.


WARNING! Without the ATLAS TTL Isolator, only Type CF medical devices can be connected to the ATLAS Acquisition Amplifier.


WARNING! Connecting electronic devices to the TTL Ports may impact patient leakage current. Always use the ATLAS TTL Isolator when connecting to the TTL Ports.
