1 Terminals for the external display and adjustment unit
2 Contact pins for the display and adjustment module or interface adapter
If inductive loads or stronger currents are switched through, the gold
plating on the relay contact surface will be permanently damaged.
The contact is then no longer suitable for switching low-voltage
circuits.
