RAVIOLI
Logo Series DC Contactor
The range of LOGO series type TL20 contactors, which are both compact in size and powerful, has been designed in accordance with the safety requirements as set out in the EUROPEAN DIRECTIVE 2006/42/CE as well as with Norms CEI EN 60947-4-1 and EN 1175-1.
The products included in the range are suitable for the traction and material handling sectors using direct current and can be applied to lift trucks, industrial cleaning machines, various services on board ships and boats as well as to road and rail transport vehicles
Coils
The d.c.coils feature terminals with 6mm double connections. Standard duty is in intermittent mode (50%). Maximum working time is 15 mins (temporary duty).
Normalised voltages: 12 - 24 - 36 - 48 - 72 - 80 - 96V. The following are available: reduced consumption coils for continuous duty-option P.
Main contacts
These contactors have double breaking contacts, in Ag special alloy, resistant to arc and suitable for heavy duty.
The contacts are also available as spare parts.
Further options
Option M - magnetic blowouts
TL20M contactors featuring permanent magnets are recommended for voltages ≥48V dc.
In this case the polarities indicated on the cover must be respected. 
Option V - dust protection
Closed contact housings can be applied to protect the contactor from oil splashes and dust.
This option cannot be used on contactor types with magnets. Option A - auxiliary contacts
A microswitch of 1NO+1NC auxiliary contacts can be supplied mounted on the TL20 types of contactors.
Operating current (resistive load) 5A-24Vcc

Tecno Series DC Contactor
The TECNO series contactors' range, compact but powerful, has been designed to be suitable for the traction and material handling fields using direct current.
Such contactors can be applied to lift trucks, industrial cleaning machines, various services on board of ships and boats, as well as to road and rail transport vehicles.
Coils
The d.c. coils feature terminals with 6 mm connections for the TECNO 6 series and screw connections for the TECNO 4 series.
Standard duty is :
- for T 106, T 206 intermittent mode (80 %)
- for T 154, T 204 intermittent mode (80 %)
- for T 106 C , T 206 C intermittent mode (50%) with maximum working time of 15 minutes ( temporary duty ).
Normalized voltage is : 12 - 24 - 36 V
Different types are available as follows : reduced consumptation coils for continuos duty - option P .
Integral protection
The cover is completely protected from oil, water and dust.
Main contacts
The contactors have silver alloy double breaking contacts, resistant to arc, suitable for heavy duty. The TECNO 6 Series is formed also by contactors with main contacts 1 NO and 1 NO+1 NC ; further it is possible to provide a motor reverser that includes both the d.c. contactors 1 NO+1 NC with the electrical connections. The NC contacts are not suitable for making or breaking current.
Correct use of the motor reverser
The used contactors have fast drop-out time (8 msec) and relatively long pull-in times (approx. 25 msec).
In this way, safe reversals can be carried out the risk of the contacts being closed at the same time. The use of suppressor diodes, however, increases drop-out time, and therefore it is important to choose the most suitable type of suppressor (diode+resistor).
