The diagram to the right
shows how the state of the
the Relay 2 Outputs
change the as Relay 2
Input is set to 0Volts
(connected to Ground)
using a jumper connection.
The left side shows that
when Relay 2 Input is not
set to 0Volts, Relay 2
COM and Relay 2 N.C
have continuity. The right
side shows that when
Relay 2 Input is set to
0Volts, Relay 2 COM and
Relay 2 N.O. have
continuity.
The diagram to the right
shows how the state of the
the Relay 1 Outputs
change the as Relay 1
Input is set to 0Volts
(connected to Ground)
using a jumper connection.
The left side shows that
when Relay 1 Input is not
set to 0Volts, Relay 1
COM and Relay 1 N.C
have continuity. The right
side shows that when
Relay 1 Input is set to
0Volts, Relay 1 COM and
Relay 1 N.O. have
continuity.
