FEATURES
This card lets you learn to control automation interfaces using Node-RED. From "Hello World" to PID looks, it is the ideal teaching platform for student, teacher or hobbyist. It brings to Raspberry Pi all the common interfaces needed to connect to the automation world:
DESCRIPTION
Although the variety of sensors and actuators is almost unlimited, they can all be grouped in three categories, based on their electrical interfaces:
1. Serial communication - RS-485 is the dominant choice, due to its ability to support multiple devices with excellent noise immunity at long distances.
2. Digital inputs and outputs - From find simple switches, contacts and pushbuttons, to any circuit which can be powered by a relay.
3. Analog inputs and outputs - Temperature, pressure, humidity, level, position, light and other sensors. Motors, linear and rotary actuators, and many many other devices have analog inputs and outputs. The industry standards are 0-10V and 4-20mA current loops.
POWER REQUIREMENTS
The I/O Learning Card needs 5V/50mA to operate with the relays off, or 200mA with both relays on. It is powered from the Raspberry Pi through the GPIO connector. A Raspberry Pi power supply able to provide minimum 3A is recommended.
RS485 PORT
The Card contains a standard RS485 transceiver which can be accessed by the serial port of the Raspberry Pi. MODBUS protocol can be run on Raspberry Pi to access industry standard sensors and actuators.
PLUGGABLE CONNECTORS
Pluggable connectors ease connecting the card to external devices. All the connector plugs are included in your kit.
DISPLAY LEDS
Nine LEDs on the bottom edge of the card show you the status of the inputs and outputs. The leftmost LED shows when the power is connected to the board.
The next two LEDs, labeled IN1 and IN3, show the status of the corresponding opto-isolated digital inputs.
The middle four LEDs are general purpose. They can be connected in software to show the status of any input or output. They can also be programmed to light at a certain input or output level. For example, you can learn how to turn on a LED when a temperature reaches a threshold. You can also blink a led slower when a temperature is relatively low, and faster as it approaches a preset limit.
The two rightmost LEDs are routed to the corresponding relays and show when the relay coil is activated.
0-10V INPUT AND OUTPUT
Zero to 10V Input can be used to sense voltage levels from devices such as thermistors, humidity sensors, or photoresistors. Zero to 10V output can be used for actuating industry standard devices such as lighting controller.
4-20mA CURRENT LOOP INPUT AND OUTPUT
Widely used industry standard 4-20mA current loops can be used to control remote devices over long distances with high noise immunity.
PUSH BUTTON
A pushbutton is provided to be able to add manual input to any system. The button can also be used by Node-RED or other Raspberry Pi programming in an arbitrary manner. The first Tutorial lesson gives some examples from saying "Hello World" to sending SMS or email messages.
PWM MOTOR
The Motor port can drive a 5V/100mA DC Motor. You can learn how to control the speed and the direction of the motor from the command line, Python or Node-Red graphical user interface.
TWO SERVO INTERFACES
Since we ran out of processor resources, the servo ports are multiplexed with the analog output ports. The servo ports connectors consist of a 2x3 jumper where you can plug directly any of the readily available servos at Amazon or elsewhere.
SELF TEST LOOPBACK CABLE
The card is designed such as all inputs and outputs are in symmetrical pairs and can be self-tested with a loopback cable. The exceptions are the Motor and Servo ports, which cannot be tested with the cable. The self-test software detects automatically the position of the cable and reports accordingly the test results. The following tests can be performed:
DOWNLOADS
SOFTWARE
You can write your own application using the Command Line or Python Library provided. No programming is required if you use the Node-Red nodes we supply. You can drag-and-drop the functional blocks to design your application.
Node-RED PROGRAMMING
Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to design flows using nodes from a large library covering a wide range of automation tasks.
The Learning Kit native Node-RED nodes included in the repository make it easy to interface with the hardware.
Node-RED TUTORIAL
The Tutorial will help you use the Learning Kit with Node-RED without writing a single line of code. It will show you how to use Node-RED to control each of the interfaces of the Learning Kit. It will start by building simple flows using the pushbuttons and the LEDs and advance to the point where you can control devices over the internet.
You can start learning Node-RED today without waiting for the Learning Kit. You will start by sending "Hello World" greetings to your screen or your speakers, and advance to sending emails and SMS messages to your smart phone.
