Switch input output connection method


Valid (with signal) : when DC6 ~ 24V voltage is applied to an input port (connect I* port and COM port), the input port is considered to be valid (valid), and the minimum duration of valid signal is >=100ms

Invalid (no signal) : when the voltage on an input port is less than DC3V(connection disconnected), it shall be deemed as invalid (invalid). A button, switch (travel switch), proximity switch, etc. can be connected on each input port (see the figure below).


Output maximum switching voltage: 250VAC/30VDC;

Maximum switching current 5A.
