Definition
The input energizes when high-level voltage is
applied to the input terminal (active high). Connect
the power supply VDC (-) to the DC COM terminal.
The input energizes when low-level voltage is
applied to the input terminal (active low). Connect
the power supply VDC (+) to the DC COM terminal.
