    Tulip I/O Gateway Technical Specifications

    Here are all the technical details of the Tulip I/O Gateway.

    Warning

    **On November 1, 2021, Tulip will no longer sell I/O Gateway devices, this article still applies to Edge IO and Edge MC devices. Learn More

    Voltage supply, Current Consumption, and Conditioning

    • Nominal supply: 24V (Vin_min: 12V Vin_max: 30V)
    • Nominal supply current: 250mA (depends on number of USB devices connected)
    • Nominal power consumption: 6W
    • Undervoltage Lockout: 11.5V
    • Overvoltage Lockout: 30.5V

    Features

    • Reverse polarity protection
    • Overcurrent protection
    • Miswire and reverse current protection
    • Surge protection

    Usage

    • Use either a Tulip provided Factory Kit power supply or a regulated 24V input

    Grounding and Earth Connections

    • Chassis (including the DIN mount) and 24V Return are internally connected
    • Optionally, pin 2 of the supplied 3-terminal power connector can be referenced to earth
    • Input banks A and B on the Gateway feature an additional grounding pin reference to the 24V return for convenience

    Recommendations

    • In production, DIN rail should be held at earth potential.
    • Optionally, pin 2 of the supplied 3-terminal power connector can be referenced to earth.

    User I/O

    • Two user buttons A and B can be used for device resets
    • Hold Buttons A and B for 5 seconds to perform a factory reset
    • Hold Button A for 5 seconds to enable the Tulip Access Point
    • Hold Button B for 5 seconds after a plug cycle to auto-enable Tulip remote support
    • One reset button (resets CPU)
    • Heartbeat/Alert LED for device diagnostics

    Temperature Range (Operating / Storage)

    • 0 - 75 ℃

    Humidity
