Product and function description
The N 262E01 binary input device is a 6 module units
wide DIN rail mounted device in N-System dimensions
with 8 inputs for potential-free contacts. It enables both
statuses (contact is open or closed) and changes in status
(contact became opened or closed) to be recorded by
means of voltage impulses generated inside of the de-
vice. It can therefore be used, for example, to monitor
the switching or operating states (whether a device or a
plant is switched on or off, whether a limit violation or a
malfunction or an alarm is being signalled), to record the
change of status when switching on or switching off
(whether a switch or a pushbutton was activated,
whether it was activated for a shorter or longer period)
and to record and count changes of the switching status
(i.e. pulses) with a minimum on-time of the contact of 70
ms and a max. pulse succession of up to 5 pulses per
second, without or with monitoring of the number of
pulses counted until a predetermined threshold has been
reached or exceeded.
At each input a red LED shows whether the connected
contact is open (LED is off) or closed (LED is illuminated).
The N 262E01 has an integrated 230 V power supply in
order to supply the electronics. This power supply en-
ables the generation of the voltage pulses for checking
the switching statuses and for displaying them via the
LEDs even when there is no bus voltage present.
Note: The device is without function after the application
program has been “unloaded” with the ETS. The status of
the inputs is also no longer displayed in this case.
Application program
The “25S8 Binary Input Device 980903” application pro-
gram, which can be downloaded up from the ETS3.0f,
supports a multitude of applications and enables one of
the following functions to be assigned to every input:
-
Switching status / binary value transmission
-
Switching, edge-triggered
-
Switching, short / long operation
-
1-button dimming
-
1-button solar protection control
-
1-button group control (sequence control)
-
1-bit Scene control
-
8-bit Scene control
-
8-bit value, edge-triggered
-
8-bit value, short / long operation
-
16-bit floating point value, edge-triggered
-
16-bit floating point value, short / long operation
-
8-bit pulse counting without threshold check
-
8-bit pulse counting with threshold check
-
16-bit pulse counting without threshold check
-
16-bit pulse counting with threshold check
-
32-bit pulse counting without threshold check
-
32-bit pulse counting with threshold check.
Using the ETS, one of the following functions can be al-
located to one input pair, i.e. to two neighbouring in-
puts:
-
2-button dimming with stop telegram
-
2-button solar protection control.
