A4. DB-16R Relay Board
The DB-16R is a 16-channel relay output board consisting of 16 Form C relays that enable efficient
switching of a load using programmable control. It is both a connector and functionally is
compatible with 785 series boards, but with an industrial type terminal
block. The relay is powered by applying a 5 V signal to the appropriate
relay channel on the 20-pin flat connector. There are 16 LEDs for each
relay, which illuminated when their associated relay is activated. This
board includes a screw terminal that can be used to connect an external
power supply in order to prevent overloading your PC’s power supply.
The application example for the DB-16R in the PIO-821 is illustrated in below figure.
