Timer relay a-collection

Timer relay a-collection
Art. no.: 4098560
Function Op, operation delayed: Time calculation starts when the contact on the active input is closed. After the set time the relay switches on regardless of whether the contact on the active input is closed or open. If the contact is closed again after the time calculation has been switched off, the relay turns off and the time calculation starts again.
Function in, delayed disconnection: Time calculation starts and the relay opens when the contact on the active input is closed. After the set time the relay switches off regardless of whether the contact on the active input is closed or open. If the contact is closed again after the time calculation has been completed, the relay turns on and the time calculation starts again.
Function Dr, drop out delayed: The relay opens when the contact on the activation input is closed. When the contact is broken the time calculation starts. After the set time, the relay turns off. If the contact on the active input is closed while the time calculation is being made, the time calculation is reset while the relay is still turned on.
Flashing Function - Function R: (ON time first), (Function, Rb, OFF time first). When the control voltage is connected, the time starts to be calculated, when the period has expired the relay disengages. When the time for the disengaged relay has expired, the relay opens. This process continues as long as the control voltage is connected. The time for the rest and running time is equal. All relevant data, as well as the circuit diagram are clearly marked on the side of the relays.
Indication: 2 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is closed and flashes during the time calculation
Fuse electronic 24 V DC, Lutze
Lütze
Fuse electronic 24 V DC, Lutze
Art. no.: 2929270
Dwarf switches connected to 24 V DC often have difficulty tripping, especially with longer cable runs and thin cable area. The selectivity does not work and all groups fall before the circuit breaker resolves in the thermal area, which can amount to several minutes. Lutz's electronic fuse trips reliably even with long cable runs, which provides good selectivity without interruption of error-free groups. The rated current of the fuse is set using a thumb wheel under the safety cover, the current is adjustable between 1-10 A in 1 A steps. Three different characteristics can be selected using a second thumb wheel. Slow, medium and fast. The 24 V DC connection can either be made directly in each fuse, alternatively a distribution terminal with copper rail is connected. This option is recommended if many fuses are mounted next to each other. With the help of a sliding plate, the fuse is connected to the rail, when separating the sliding plate, the fuse is also galvanically isolated. The reset can be done via a button on the front (you can also manually disconnect the fuse via the button) or via remote control. When the fuse is tripped, the LED flashes red. There is also an output 24 V DC (open collector) that falls when the fuse trips, the output can be connected to a group with the help of a jumper, if one of the fuses in the group falls, you get an alarm. The door can be labeled and locked with a seal. The fuse has no galvanic isolation between input and output when connected to 24 V DC.
Safety switch plastic encased SA 16-25 A
Norwesco
Safety switch plastic encased SA 16-25 A
Art. no.: 3164310
Enclosed load switch/disconnectors in accordance with IEC 60947-3, e.g. for use as safety switch where required. In accordance with applicable regulations, a safety switch must be connected in a main circuit to disconnect the plant section during mechanical or electrical work and to prevent unintentional reconnection of the plant while work is in progress. Since a safety switch is only to be used to disconnect a plant section, the plant’s electrical circuit must have both a switching device for start and stop, and a separate switching device as a safety switch.

• modern dirt-repellent form
• strong connection terminals with screws in screwed position
• generous connection space with plenty of room to run cables
• earth and neutral rail as standard, 4-pole with earth rail only
• necessary throttling nipples and standards-compliant
• signs are included as standard
