Overview
Description
Figure 1 View of devices
In conjunction with a 24 V power supply, the selectivity module is used to distribute the load
current across several branches and to monitor the individual currents in these branches.
Faults in the individual branches caused by overload or short-circuit are detected and
selectively switched off, so that the fault does not impact the other load circuits. This means
fast troubleshooting and minimized downtimes.
The key benefits of the product include:
● A maximum of 4 load branches are monitored for each module
● The response threshold can be continually set for each output using a potentiometer
● Overcurrents are reliably switched off, independent of the cable length and cable cross-
section
● The 24 V supply for the other loads is maintained
● Multi-colored LED for each output for faster troubleshooting on-site
● Floating group signal contact for remote diagnostics (for -2BA00, -2BA11, -2BA21,
-2BA51)
● Single-channel signal to serially indicate the state of the individual outputs (for -2BA31,
-2BA41, -2BA61)

Device description
Using the selectivity module, a 24 V DC output voltage from a regulated power supply can
be distributed across four load circuits. The response threshold of the output current can be
individually set for each output using a potentiometer. When the set response threshold is
exceeded, the output is automatically switched off according to a defined switch off
characteristic, and can be switched on again after a wait time using a pushbutton or remote
reset (SITOP PSE200U). The status of the output is displayed using a multi-color LED for
each output. The status of the outputs can be processed via a group signaling contact or via
a serial single-channel signal.

1. After an electronic shutdown (LED of the output is lit red), allow a wait time of 20 seconds
to elapse.
2. Press the reset button ⑥ of the particular output
Electronic shutdown was reset, and the output has been switched-on again (LED of the
output is lit green).
Remote reset:
Alternatively, a remote reset signal can be used. The non-isolated 24 V input (referred to the
"0 V" terminal of the module) can be used at terminal "RST". A reset is executed for an input
level of > 15 V.
Note
The rising edge of the remote reset signal is evaluated, i.e. for an additional remote reset
signal, initially a voltage level of 13
V must be fallen below.
Using a remote reset signal at terminal "RST" all outputs that were shut down electronically
due to an overload are reset at this time. Prerequisite: The output is ready to be reset, i.e.
the electronic overload shutdown occurred longer than 20 s ago (LED of the output flashes
red).
Note
If, after a reset, the cause of the overload is still present, then the output is again
automatically shut down. Before carrying out a reset, remove the cause of the overload to

2.7
Setting the switch-on delay time
For specific loads, it can make sense to sequentially switch-on the outputs in order to reduce
the peak inrush currents, and therefore the load on the power supply. To achieve this, the
individual outputs of the selectivity module can be switched-in with a time delay between one
another in a fixed sequence (output 1 ⇒ 2 ⇒ 3 ⇒ 4). The delay time set between the
individual outputs is the same for all of the outputs. When supplied, the delay time is set to
0 ms (all outputs switch on simultaneously).

Programming the sequential switch-on delay
For specific loads, it can make sense to sequentially switch-on the outputs in order to reduce
the peak inrush currents, and therefore the load on the power supply. To achieve this, the
individual outputs of the selectivity module can be switched-in with a time delay between one
another in a fixed sequence (output 1 ⇒ 2 ⇒ 3 ⇒ 4). The delay time between the individual
outputs is the same for all outputs, and can be set to 0 ms, 24 ms or 100 ms. The selected
setting is also kept for an unlimited time even when the power fails, and can be changed as
often as required. When supplied, the delay time is set to 0 ms (all outputs switch on
simultaneously).

2.7 Setting the switch-on delay time
Selectivity modules
Manual, 11.2017, C98130-A7579-A1-3-7629 27
Procedure when setting the delay time:
1. Keep the reset button ⑥ pressed for approximately 8 seconds. The selectivity module
changes into the programming mode, all LEDs are lit red and the outputs are shut down.
2. Release the reset button. The LEDs signal the selected delay time using a specific flash
rhythm. The meaning is as follows:
LED
Meaning
flash 1x simultaneously red, followed by a 2 s pause
Delay time of 0 ms selected
flash 2x simultaneously red, followed by a 2 s pause
Delay time of 24 ms selected
flash 3x simultaneously red, followed by a 2 s pause
Delay time of 100 ms selected
The flashing rhythm is repeated after a pause of approx. 2 s.
3. Briefly press the reset button; this causes the actual setting to be moved forward by one
stage (0 ms ⇒ 24 ms ⇒ 100 ms ⇒0 ms). Press the reset button several times until the
required setting is signaled.
4. Then keep the reset button pressed for approximately 8 seconds. All LEDs light up red.
5. Release the reset button. The selectivity module saves the delay time that has been set
and sequentially switches on the outputs.
The LEDs of the outputs are lit green, and the selectivity module is again in its normal
operating mode.
Note
In the programming mode, if the reset button is not pressed within 30
s, then the selectivity
module automatically returns to the normal operating state without saving any change made
to the delay time. The setting is also not saved if, while program
ming, the supply voltage
fails.
Note
The selectivity module outputs are shut down while programming, and are automatically
switched
-on again after the programming mode is either manually or automatically exited.
They are also automatically switched on
again after the voltage returns after a power failure!

Setting the sequential switch-on delay
The switch-on delay is set at selector switch ⑪. When delivered, DIP switches "A" and "B"
are in position "0" (no switch-on delay).
Procedure when setting the delay time:
With the selectivity module in a no-voltage condition, set DIP switches "A" and "B" to the
required delay time.
No delay, all four outputs are simultaneously switched-on (condition when delivered).
25 ms delay between the outputs being switched on.
100 ms delay between the outputs being switched on.
Outputs switched on depending on the load: The next output is switched on as soon as the
current of the previous output lies below the selected response threshold.
The next time that the selectivity module powers up, the outputs are sequentially switched on
corresponding to the selected delay time.

The supply is connected via input terminal ①, designated "24 V" and the 0 V terminal ②,
designated "0 V"; the "0 V" connection is not used for the load supply, but only to supply the
internal electronics of the selectivity module (terminal cross-sections, see Figure 2-2
Terminal data (Page 13)).
NOTICE
Overload of the wiring
The "0 V" connection is only used to supply the internal electronics of the selectivity
module. The 0 V of the connected loads must be routed directly to the power supply using
separate cables!
NOTICE
Overload of the wiring
The input terminals of the selectivity module are designed for a maximum input current of
40 A. This must be taken into account when connecting several selectivity modules in
parallel using "loop through". If the total current demand of all selectivity modules
connected in parallel is more than 40 A, then the maximum current should be reduced to
40 A per branch by using additional feeder cables directly from the power supply to the
selectivity modules connected in parallel.
