306-0008-002-001 Rev500 Neets 4 relay
Description
The Neets 4 Relay box gives you up to 4 dry contact relays that each can be controlled by a control input
1
(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.

“Control inputs” is the name used in this manual for the 4 inputs that allows the Neets control system to
control it directly.
