This Arduino compatible PLC Kit offers a very affordable opportunity to add a programmable logic controller to many kinds of projects and machines like lighting, HVAC, greenhouses, water treatment or smokehouses. It can help you control your Halloween decoration or your manufacturing equipment.
CANADUINO MEGA2560 300-24 PLC fits a very small budget but delivers power and versatility equal to 10x more expensive professional process control devices.
Arduino PLC MEGA2560 300-24 PLC basic features:
– 8 analog 0-10V inputs (10-bit res.)
– 8 analog inputs or GPIO (TTL level)
– 8 analog 0-10V outputs (8-bit res.)
– 2 interrupt inputs
– 16 digital 3.3-24V inputs
– 14 digital 250V/5A relay outputs
– 1 x I2C Bus, 1 x SPI, 2 x RS232 *
Arduino MEGA2560 is not included but compatible modules are available here in the store.
MAXIM MAX233CPP is not included (required for 2 x RS232 port if needed)
MEGA2560 300-24 PLC is a Do-It-Yourself kit comprising only through-hole parts with a pin pitch of typically 2.5mm or more and is easy to build using basic electronic tools.
There are 16 optoisolated digital inputs, typically recognizing any voltage 3.3V to 24V DC as HIGH level, due to the included optocouplers with a CTR of about 100-200.
The 14 digital outputs are fast-acting relays OMRON G5NB-1A-E with about 10ms operation and release time and high-capacity contacts. The maximum load can be 5A @ 250VAC or 30VDC.
Analog inputs and outputs on screw terminals are designed for 0-10V operation, typically used for light dimmers or motor drivers, for example.
Several 10V output terminals are available to deliver 10V levels for example to a potentiometer, to generate the analog input signal. The 10V level is adjustable in a range of about 9-11V and is also used to drive the output relays. The 10V supply outputs in the analog input section are over current protected (trip point 200mA) by a self-resetting fuse.
I2C bus and SPI are exposed for an easy connection to auxiliary devices, for example, the optional available RTC and micro-SD module. There are no pull-up resistors for the I2C bus on board; please make sure your external device has these resistors assembled. I2C and SPI data lines are direct connections to the MEGA2560 and do not have additional protection.
A D-Sub-9 PCB connector and the DIP-20 socket for 2 RS232 serial ports are included, but not the MAX233CPP serial port chip. The MAX233CPP is available from our online store and any renowned parts distributors. With the RS232 option, the PLC is easily connected with machines, frequency motor drives, computers or HMI devices. Both ports are available on the same 9-pin male D-Sub port. Port COM2 is available on pins 2 and 3, while COM3 is available on pins 7 and 8. The 1st serial port is used for programming and monitoring (RX/TX through USB).
Substitute parts: If we can’t source the value of the part as shown in the schematics, we will ship the kit with a substitute part close enough to guarantee proper function. Please always install the exact matching parts first, and install the substitutes at last. This way, you will not mistakenly install the wrong parts.
A DIN rail mount (tray) with outer dimensions of 212 x 128mm is available as an option and snaps on standard 35mm DIN rails.
