Functional Description
The KL2612 output terminal switches two relays, each having one
changeover contact, under control of the automation device. The signal
state of the bus terminal is indicated by an LED. If the LED is on, it means
that the contact between 2 and 1 or, in the case of the second relay,
between 6 and 5, is closed. The KL2612 Bus Terminal does not have a
power contact, which means that a voltage that has been passed on
through earlier terminals via the power contacts must be fed in again after
a KL2612.
LED display The signal LEDs indicate the operational state of the associated terminal
channel.
On:
Changeover between 2-1 (6-5) closed
Off: Changeover between 2-3 (6-7) closed
Or:
A watchdog timer overflow has occurred. If no process data is handled by
the bus coupler for 100 ms, the green LED goes out and the outputs are
set to 0.
Process data The bit-width in the process image is 2 bits.
