3.3.6
An AC terminal can be inserted in the 24 V DC area. The effects are described in Table 3-3.
A 24 V DC terminal cannot be inserted accidentally in an AC area as these terminals are
not mechanically compatible.
Effect/description
Specified interface between a 24 V DC area and an AC area.
The AC power terminal consists of two function parts:
–
–
No direct danger to people.
If the output is activated, the Triac output may be forced to trip and no longer switch off
because the supply voltage does not pass through zero.
No danger to people or machines.
The input does not function due to missing ground.
No direct danger to people.
The module has no diagonal routing, so there is no direct danger from the terminal, even
with a 230 V connector. This means that the shortest isolating distance is the distance
from one connector to the next. This isolating distance is not permitted. Therefore, insert
a distance terminal (order designation IB IL DOR LV-SET) before and after the relay
terminal.
No danger to people or machines.
The terminal offers neither diagonal routing nor connector connection.
The left-hand part interrupts the jumpering of U
The connections for the power supply and the jumper contacts for L, N, and PE are
on the right-hand part
NOTE: Possible malfunction
This is likely to be caused by a malfunction of the actuator connected to the
relevant output.
