MEDIOEX-V2 is basically Raspberry Pi shield and it is suitable Raspberry 2/3/4 and also Zero. Even if Raspberry has been a popular worldwide hobby in the last decades, we have transformed it into an engine which could be utilized in industrial environments thanks to our rich experience in the heavy industry. This document contains application samples regarding the commissionning of the card. Detailed information on MEDIOEX is shared in this document. The student and engineers may utilize in industrial environments thanks to such information on Raspberry Pi shared in this Document.

MEDIOEX contains the following features:

  • 16ch isolated Digital Input

  • 16ch Digital Output ( 4 ch 250V relay, 12 ch 24VDC transistor output)

  • 4ch 12bit Analog Input

  • Real time clock

  • Rs232 OR RS485 via D-SUB

  • Internal temperature sensor LM75bd

  • External I2C terminal output

MEDIOEX-V2 should powered with an external power supply of 24VDC. You can start MEDIOEX through a connection between MEDIOEX and J11 connecteur, as shown in the below picture or directly with a PC adapteur with a 24VDC.

PE2A provides the consumers with MEDIOEX cards together with open sources software. The consumer may make modifications on the code of the open source software. You can have access to detailed information via the below link as to the code functions.




Node js:

MEDIOEX provides physical Digital-Analog Input based SPI. You can even use serial port RS232 and RS485. The consumer may first install "bcm2835.h" library if they aim to code in C programming language.
