How to connect…
Connecting the Relay – 8 to the control system.
Using I/O pins
If you want to control one or more relays from a digital output, like any of the Neets Control system
range provides, you can do this. By default the Relay – 8 is configured to link the I/O pins to the re-
lays. This means that you can connect the I/O of the Neets Control system directly the Relay – 8.
Not using a Neets Control system to control the Relay – 8 ? Our I/O can interface with all system
that can pull the Input low. To test this simply make a short circuit between the I/O pin and GND
to active the relay.
If the Relay – 8 has been used before it is recommended to reset the Relay – 8 to make sure that
no settings that prevents this operation are saved in the unit (See section page 13).
Using RS232
When controlling the Relay – 8 by RS232 you have to connect the RS232 port from the control
system to the Relay – 8 RS232 port 1 (T1,R1 and G).
The command that has to be sent can be found in the section on page 14.
Remember, controlling Relay – 8 by both RS232 and LAN is not possible at the same time.
