MIO2 module

MIO2 - Modbus communication module

MIO2-module

Is used for connection the CO2- moisture- and motion sensor for example, or the TIMERBUTTON for the EXact2 control. 

How many sensors can be connected per MIO2-module?

The sensors emit a 0 -10 V signal (CO2- or moisture sensor for example):
1 sensor per MIO2-module

Sensors which emit an ON/OFF signal (such as a PIR sensor or TIMERBUTTON):
4 Sensors in parallel connection per MIO2-module.

Connect to VEX via modbus.
