Wiring example when used with XL50:
Relay terminal 17 controls the change-over contact K3.
Relay terminal 18 controls the ON contacts K1, K2.
Ground can be looped through terminals 2/3.
Wiring example when used with
XL100C:
The relay modules are supplied via the special relay connection of the controller (terminals 65/66)
IMPORTANT
Important during connection: 1. Correct polarity
2. Under no circumstances may
a relay module be connected to the reference voltage.
Several relay modules can be connected in series via the bridged terminal pair:
Plus pole: Terminals 11/12 of the relay
Minus pole: Terminals 13 to 16 of the relay
L (Fig. left)
Terminal 17 controls the changeover contact K3. Terminal 18 controls the ON contacts K1, K2. Ground can be looped through terminals 2/3.
