Driving Capability
Maximum driving capability of each output load of each channel is 100
mA and overall maximum driving capability is 500 mA.
Connecting RELAY
When the load is a RELAY, it’s not necessary for you to connect an exter-
nal diode to absorb pulse noise because there is an instant over voltage
protection diode onboard.

Warning: DO NOT connect the 24 V power to output
channels directly when there is no load. This
will damage the board!
