1)
Short-circuit protection responds with line resistance 9 ohms at 24 V DC, 30 ohms at 60 V DC.
2)
One digital input is permissible as minimum load.
3)
At L+ voltages of more than 72 V, the logic 0 of the output can rise to 13 V. A digital input follower will interpret this signal
as a logic 1 (possible fault).
