Box 10 09 53, D-93009 Regensburg Subject to change without further notice2.7.3.2/1Product and function descriptionThe N 262E01 binary input device is a 6 module unitswide DIN rail mounted device in N-System dimensionswith 8 inputs for potential-free contacts. It enables bothstatuses (contact is open or closed) and changes in status(contact became opened or closed) to be recorded bymeans of voltage impulses generated inside of the de-vice. It can therefore be used, for example, to monitorthe switching or operating states (whether a device or aplant is switched on or off, whether a limit violation or amalfunction or an alarm is being signalled), to record thechange 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 70ms and a max. pulse succession of up to 5 pulses persecond, without or with monitoring of the number ofpulses counted until a predetermined threshold has beenreached or exceeded.At each input a red LED shows whether the connectedcontact is open (LED is off) or closed (LED is illuminated).The N 262E01 has an integrated 230 V power supply inorder to supply the electronics. This power supply en-ables the generation of the voltage pulses for checkingthe switching statuses and for displaying them via theLEDs even when there is no bus voltage present.Note: The device is without function after the applicationprogram has been “unloaded” with the ETS. The status ofthe inputs is also no longer displayed in this case.Application programThe “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 ofthe 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.Connection exampleinstabus EIBN 262E01Bus coupling unitABCDEGHEingangInputABCDEGH230 V AC
