    Isolation

    The USB-8502 offers port-to-port (2-port variant) and port-to-USB (both 1 port and 2 port) isolation.

    Isolation Voltage

    Port-to-earth ground

    Continuous

    60 VDC, Measurement Category I

    spd-note-note
    Note  

    The COM signals of CAN ports on the USB-8502 are not connected to the USB ground. This isolation is intended to prevent ground loops and does not meet UL ratings for safety isolation.

    Maximum Voltage on CAN Ports

    This voltage is the maximum voltage that can be applied or output without creating a safety hazard.

    Connect only the voltages that are within these limits.

    Port-to-COM

    -27 VDC to +40 VDC max, Measurement Category I

    Measurement Category I is for measurement performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

    spd-note-caution
    Caution  

    Do not connect to signals or use for measurements within Measurement Categories II, III, or IV.

    spd-note-note
    Note  

    Measurement Categories CAT I and CAT O (Other) are equivalent. These test and measurement circuits are not intended for direct connection to the MAINs building installations of Measurement Categories CAT II, CAT III, and CAT IV.
