3.3.4. GPIO-Out
The GPIO-Out connector provides 4 general-purpose outputs. 4 independent solid-state relays are
used to connect
*_A
pins to their corresponding
*_B
pins. Each output is rated for 60 V DC, 400 mA
max., and the signals connected to each output must be within 50 V DC from chassis/earth ground.
There is no polarity dependency between
*_A
and
*_B
pins.
Connect external equipment to this connector.
