16DO and 16DOR Boards
Setting the DIP Switches
Set the DIP switches as described in the table below before installing the 16DO/DOR board and
wiring the digital output devices.
Wiring Digital Output Devices
To wire a digital output (DO) device:
1.
Mount the digital output device according to the manufacturer’s specifications.
2.
Complete the wiring. If the DO is used to energize a relay, install a diode in parallel with the
relay coil to absorb transients when the relay is de-energized. A transient protection
diode (user
supplied) is necessary on the 16DO board.
3.
Connect a 5 to 24 VDC power supply to port J6. The voltage needed depends on the relay
requirements of the DO points. Pins 1, 3, 5, and 7 on ports J2, J3, J4, and J5 get their DC voltage
from pin 1 on J6.
