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
- 5% - 80% rel hum. non-condensing
Processor
- TI Sitara ARM Cortex (AM3358)
- 512M DDR3 Memory
- 4GB eMMC storage
OS/Software
- Tulip OS (Yocto-Linux based)
- Nominal I/O Gateway to Factory Bandwidth: 10Hz
- Nominal I/O Gateway Bandwidth: 240Hz
