===== Basic features and parameters =====
* Compatibility with RaspberryPi i RaspberryPi+ minicomputers
* Four binary outputs, including:
** Two relay outputs
** Two transistor outputs
* Output states monitored with LED
* Extended I/O pins of Rpi minicomputer
* Screw terminals ARK

'''Relay outputs'''
* Two SPDT outputs
* Maximum switching voltage: 250VAC/30VDC
* Maximum switching current (resistive load): 10A
* Recommended maximum load currents: 5A/240VAC, 5A/28VDC

'''Transistor outputs''
