CONFIGURING THE RELAY BOX
Each relay box has 8 outputs and all of them are
individually configurable. The outputs are configured via a program in a PC or alternatively from a
configuration unit that is unique to the customer.
The output can be configured to be active in various
ways.
Some examples:
Momentary - Active as long as a lever is pulled.
(monostable)
An output is normally activated by pulling a lever in
an ON-OFF menu on the controller. A text describing the function is displayed in a position corresponding to the lever. (Figure 1)
Alternating - Active until the lever is pulled the next
time. Every other time on and every
other time off (bistable).
However, a relay box output may also follow a
lever in any menu. There is an option to activate
different outputs depending on whether the lever
is moved away from or towards the operator when
used in proportional menus.
Memory
- An output that is active when the
controller is stopped is reactivated
automatically when the controller
starts over.
Retention
In addition to this the output can be configured to
become active at a specific action in the system.
Safety relevant functions must not be connected to
outputs that are configured to remain on even if the
stop button is pressed. The safety philosophy of
the system relies on that an output is deactivated
automatically if some malfunction is detected, or if
the emergency stop button is pressed.
- An output remains active even after
pressing the stop button on the con-
troller.
Next page summarizes all configuration options for
the relay box outputs. Olsbergs relay box provides
great flexibility.

OLSBERGS RELAY BOX
Olsbergs Relay box is part of our modular system of boxes with different functions.
The relay box is normally positioned together
with the Decoder, where the Decoder constitutes the cover and the relay box the bottom.
(Figure 1)
Figure 1
Figure 2
If more relay functions are required, additional
Relay boxes can be added to the system.
Figure 3
A cover-mounted Relay box with an empty bottom is used for one additional Relay box.
(Figure 2)
With two additional Relay boxes a cover and
bottom module is fitted together. (Figure 3)
If the system contains one or more additional
Relay boxes, it is important to connect it/them
before the Decoder. This is because the E0854
strapped plug has to be connected in the Decoder. (Figure 4)

+24 V
The ground is connected here for functions that require that both +24 V and
ground are connected. There are 4 ground terminals.
There are 8 outputs in each Relay box.
Outputs 1 and 2 can drive 2.5 A /output.
Outputs 3 - 8 can drive 1 A /output.
However, the total load for the relay box must not exceed 10 A.
Output 1 is normally intended for connecting a horn. The relay box is configured
for this from the factory. With two or more Relay boxes, output 1 can be reconfigured to an optional function.
Xenon lights should be connected to outputs 3-8 due to their characteristics. If
the nominal current consumption of the light exceeds 1 A, two or more outputs
may be used in parallel to provide sufficient power.
Terminal block
External +24 V supply is connected here.
As the relay box can supply 10 A, this should be taken into account when dimensioning cables.
