Description
The Neets 4 Relay box gives you up to 4 dry contact relays that each can be controlled by a control input1
(Supported by all Neets Control systems) or by RS-232. The relay box can be used in ether low voltage or
high voltage (230VAC) mode, and never at the same time(The applies for the Relay 1 and 2 when using the
“Screen” connector).
On each of the four relays you have access to both the NO (Normal open contacts) and the
NC (Normal close contacts). This gives you the opportunity to use it according to your
needs.
When using the Neets 4 relay box you have the benefit of selecting what type of voltage
you want to use at installation time.
The flexibility of the relay box offers you the possibility to control high voltage or low voltage (Please note
that high and low voltage cannot be used simultaneously).
Safe way to control a screen or lift
The relay box, offers you the possibility to link two relays together and thereby adding extra security when
controlling e.g. screen or projector lift.
When two relays are linked together only one of the relays can be “Set” at a time.
Furthermore, you can define the time from one of the linked relays is “Released” to it is possible to “Set” a
relay again, this time adds additional protection of the connected screen/lift motor.
When using this security feature, it is active whether you control the relay box by the 4 control inputs or by
RS-232.
Note that the relay box’s relay 1 and 2 from factory is configured to control a 230 VAC screen
or lift. Using the “Screen” connector and there for you must not use the “Relay-1” and “Relay-
2” connectors.
If you do not want to use the “Screen” connector, please remove fuses F1 and F2 “Screen
5A”. Read the section “Controlling an electrical screen or lift” on page 7 for further details.
When 4 relays are not enough
The Neets relay box gives you the possibility to connect up to 4 boxes together on the same RS-232. When
doing this you get up to 16 relays that are all controllable individually by only one RS-232 port.
1“Control inputs” is the name used in this manual for the 4 inputs that allows the Neets control system to
control it directly.

All Neets control systems support up to 2 relay boxes on one RS-232 port as it is. If you want more than 2
relay boxes on a RS-232 port, you have to use an active splitter and connect it as shown on page 9.

How to connect it?
This section will explain how to connect the Neets Control –EU with the Relay box 306-0003. It will also
give some examples on how to connect an external device to the relay box. Please note that there are
several other ways to use the relay box than described in this guide.
ALWAYS be sure that 230 VAC is disconnected when installing/changing ANYTHING.
When you receive the relay box, relay 1 and 2 are already configured to run screen mode.
If you do not want to use the screen mode or control low voltage unites always remember to remove
fuses F1 and F2 (Screen 5A)

If you control the relay box with both its input controls and by RS-232, you have to be aware that if the
relay is activated by RS-232, you cannot release it with the input controls and vice versa.
When controlling the relay box from the Neets Control –EU system you can connect it like this:

Controlling a electrical screen or lift
The relay box offers you easy connection of an electrical screen or lift.
By using the screen terminals you get an easy connection of your screen and even
more the high security mode prevent you from accidentally making short circuit.
The Relay 1(RELAY-1) is now controlling the screen in one direction, and there is ONLY power to the screens
other direction (RELAY-2) when Relay 1(RELAY-1) is “Released”. Be sure to set up the software to fit this
hardware configuration.
To enable the screen mode insert the fuses F1 and F2 (Screen 5A)

Cable in/out of the box
The relay box comes with rubber globs, that allow you to use any cable size you want, and the taps inside
the box gives you a good and flexible way of safely fixating the cable.
Use the include binders to tie the cables like below or what fits your installation.
Use included
binders to secure
the cables.
When using the screen
connector, you must not use
the “Relay-1” and “Relay-2”
connector also.
Dry contacts free to be
used

How to connect more than 2 relay boxes to one RS-232 Line
A standard RS-232 line only allows you to have two RS-232 devices attached. If you need more than two,
you have to use the Neets Serial splitter 1-4 as well. Below you can see how it can be connected.
