6 Digital Input/Outputs
The QuasarMX has 2 digital input pins and 4 digital output pins which can be be read or set
via the reader. The input pins are optically isolated 24 V DC inputs as common in
automation technology in general. Up to 25 mA are needed to set the input to "high".
The output pins are 24 V high side switch DC outputs with a maximum current of 250 mA
per pin. These can be used to directly power e.g. signal towers. In total a maximum current
of 1000 mA for all pins is allowed. Outputs are equipped with internal overcurrent and
overtemperature shutdown.
The pins X2.1 and X2.2 are connected directly to the power supply input, i.e. the applied
voltage is 24 V DC. This can be used for power supply of e.g. sensors, etc. The power of
these pins is only limited by the power of the power supply used.
