LOGO Serisi - TL22
LOG0 series double pole contactors type TL22 are available in the following versions:
– 50% intermittent duty (standard version)
– 100% duty (option P)
Neither magnetic blowouts nor auxiliary contacts can be mounted
on these contactors.
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
Recommended working positions:
either horizontal or vertical with poles pointing upwards.
Correct use of the motor reverser
The used contactors have fast drop-out times (10 msec) and relatively long pull-in times (approx. 20 msec).
In this way, safe reversals can be carried out without the risk of the contacts being closed at the same time.
However, the use of suppressor diodes increases drop-out times, and therefore it is important to choose the most suitable type of suppressor (diode+resistor).

Main features
The joining of two contactors of the type TL22 or TL22P makes the construction of corresponding motor reversers possible, and these are supplied with electrical connections and with a common bracket.
Main contacts: 2x2NO
– 50% intermittent duty (standard version)
– 100% duty (option P)
Neither magnetic blowouts nor auxiliary contacts can be mounted on these motor reversers.
