DB-16R Relay Board
The DB-16R, 16-channel relay output board, consists of 16 Form C relays for efficient switching of
load by programmed control. It is connector and functionally compatible with 785 series board but
with industrial type terminal block. The relay is energized by applying 5 voltage signal to the
appropriate relay channel on the 20-pin flat connector. There are 16 enunciator LEDs for each relay,
light when their associated relay is activated. To avoid overloading your PC’s power supply, this
board provides a screw terminal for external power supply.
