Product overview
KL26xx/KS26xx 12 Version: 2.5.0
Fig. 3: KL2622-0000, KL2622-0010 – two-channel relay output terminals
KL2622-0000 / KS2622-0000
These terminals have two relays, each with a single contact, and can be used to switch mains voltage
consumers up to 230 V
AC
. The relay contacts of the terminals are potential-free and are not connected to the
power contacts.
KL2622-0010 / KS2622-0010
These terminals have two relays, each with a single contact. These terminals switch at zero voltage crossing
to protect the contacts and are especially suitable for capacitive loads such as LED lamps (or rather their
control gears). The power contacts are not passed through.
LEDs
The signal LEDs indicate the operating state of the associated terminal channel.
Watchdog timer overflow
If no process data are transmitted from the bus coupler to the terminal for 100 ms, the green signal LEDs
extinguish and the relay contacts are opened after the typical response time (
see technical data [ } 13] ).
Process data
The bit width in the process image is 2 bits.
