Outputs are isolated if output 1 (OUT1) or output 2 (OUT2) is “relay contact output” or “triac trigger output.”
If both outputs are “relay contact output” or “triac trigger output,” outputs are not isolated.
2
Outputs of DO1/DO2 and DO3/DO4 are isolated.
DO1 and DO2 or DO3 and DO4 use the same common terminal (No. 9 for DO1/DO2, and No. 21 for DO3/DO4)
and are not isolated.
