N 264E11 binary input devices, 2 x 8 inputs 8 for 12 ... 230 V AC/DC, 8 for floating contacts


The binary input device N 264E11 is a N-system DIN-rail mounted device with 8 inputs (a…h) for potential-free contacts and 8 inputs (A…H) for AC or DC voltages in the range 12…230 V. It supports the monitoring of the input status (contact closed or open response voltage applied or not) and the detection of changes of status (contact was opened or closed resp. voltage was coming or going). It can therefore be used to monitor voltages (for example whether mains voltage is present), to record switching or operating states of plants (whether 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 resp. voltage pulses with a minimum on-time of the contact resp. of the voltage 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 (LED = on) whether a voltage is applied or the connected contact closed. The N 264E11 has an integrated 230 V power supply in order to supply the electronics. This power supply enables the generation of the voltage pulses for checking the switching statuses and for displaying the signal statuses at the inputs via the LEDs even when there is no bus voltage present.
