RevPi AIO module
Use this expansion module to connect analog sensors, actuators, and temperature sensors to the Revolution Pi system.
描述
Module Introduction
In addition to three different digital I/O expansion modules, an analog I/O expansion module is also available. By using the RevPi AIO module, the Industrial Raspberry Pi can be expanded to include four analog inputs, two analog outputs, and two RTD channels. Like all I/O modules, the RevPi AIO module has a 28-pin I/O connector, and the inputs, outputs, and RTD channels are electrically isolated from each other and from the logic circuitry.The RevPi AIO module is protected against interference according to EN 61131-2, and can be operated in an ambient temperature range of -30°C to 55°C. Additionally, the analog I/O modules can be used to extend the analog inputs and outputs of the Industrial Raspberry Pi. In addition, the analog I/O modules are UL certified.
RevPi AIO
Includes 4 analog inputs, 2 analog outputs and 2 RTD channels
| Analog Input
The RevPi AIO has 4 analog inputs with a 24-bit DAC to connect to analog sensors such as level or proximity sensors. The range of current and voltage inputs supported is:
Voltage input range:
- 0~5 V
- 0~10 V
- +/- 5 V
- +/-10 V
Current Input Range.
- 4~20 mA
- 0~20 mA
- 0~24 mA
- +/- 25 mA
| Analog Output
The RevPi AIO has 2 analog outputs with 16-bit resolution for connection to an analog actuator. Supports voltage and current output ranges:
Voltage input range:
- 0~5 V
- 0~10 V
- +/- 5 V
- +/-10 V
- 0~5.5 V
- 0~11 V
- +/-5.5 V
- +/-11V
Current Input Range.
- 4~20 mA
- 0~20 mA
- 0~24 mA
|RTD (Thermal Resistance)
In addition to the 4 analog input channels, the RevPi AIO has 2 independent RTD input channels. These 2 RTD inputs enable temperature measurements from -165°C to +600°C with a high accuracy of 0.5°C using common RTD sensors such as Pt100 / Pt1000 probes, and support 2, 3 or 4 wire connections:
Supported Thermal Resistance Models:
- PT100
- PT1000
