Tulip I/O Gateway Technical Specifications

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


**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


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


  • 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


  • 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 ℃


  • 5% - 80% rel hum. non-condensing


  • TI Sitara ARM Cortex (AM3358)
  • 512M DDR3 Memory
  • 4GB eMMC storage


  • Tulip OS (Yocto-Linux based)
  • Nominal I/O Gateway to Factory Bandwidth: 10Hz
  • Nominal I/O Gateway Bandwidth: 240Hz
  • Tulip-managed OTA Updates (Requires port 9000 to be open to traffic)
  • Contact Tulip to discuss integration of additional Kernel drivers or run-time device drivers.

  • IC: ADM3251
  • Support for additional physical interfaces (RS-485, RS-422) is possible; contact Tulip


  • Wired 10/100 Mbps Ethernet Port

I/O Recommendations

  • In production environments requiring sensor/interface isolation, use a relay or other form of isolation to isolate the sensor and the input stage. Consult Tulip for additional information.


  • 6 USB 2.0 (High speed 480 Mbit/s) ports
