Type overview Type Article number Characteristics Switching actuators N 530D31, N 532D31 und N 534D31 can switch four mutually independent groups of electrical consumers via four potential-free outputs. Switching actuators N 530D51, N 532D51, 534D51 und N 535D51 can switch eight mutually independent groups of electrical consumers via eight potential-free outputs. Switching actuators N 530D61, N 532D61 und N 534D61 can switch twelve mutually independent groups of electrical consumers via twelve potential-free outputs. The switching actuators can switch resistive loads (e.g. electric heater,...

The device is a rail-mounted device in N dimension for installation in arrangements and is installed on 35 mm rails as per standard IEC 60715. The switching actuator is connected to the bus connection with a bus terminal block. The power supply is supplied via the bus voltage (no additional power voltage is required). Every actuator output has a potential-free relay with switch position display. Via the relay, the switch position can be changed with a tool. Every actuator output has one terminal each for the supply voltage (rated operating voltage AC 230 V) and the switched load. The...

Behavior with bus voltage failure/recovery In case of bus voltage failure, the current switch status and other values for each output are permanently stored. On bus voltage recovery, these values are restored. For each channel, the configured actions are also executed and, if applicable, new status values are reported. Behavior on unloading the application program After "unloading" the application program with the ETS, the unloaded device has no functions. Timer functions When configuring the device with ETS, one timer and night mode can be programmed. It is possible to set delayed...

Switch cycle and operating hours count To monitor use, with the right configuration it is possible to count and display the switch cycles and operating hours of the device. For switching actuators of type N 535, the counting of operating hours can be configured so that operating hours are only counted when there is an active current flow. Load current monitoring (only type N 535) For switching actuators of type N 535, the load check can optionally be measured and the status can be sent via the bus. The load check can also be monitored with regard to exceedance or falling short of load check...

Safety WARNING • The switching actuator should only be installed and put into operation by a certified electrician. • Ensure that the switching actuator can be activated. • Do not open the casing of the switching actuators. • For planning and construction of electric installations, the relevant guidelines, regulations and standards of the respective country are to be considered. Note on installation The switching actuators can be used for fixed installations in interior spaces, for installations in dry locations, within distribution boards or small casings with DIN rails EN 60715-TH35.
