Controller - SmartRelay 3 system

1

-

GND Optional connection of an external power supply (ground).

2

+

V_IN. Connection of an external power supply (positive pole).

3

Relay 1: NO (Normally Open). This contact is connected to C when the relay switches.

4

Relay 1: C (Common). Common connection of the changeover contacts.

5

Relay 1: NC (Normally Closed). This contact is disconnected from C when the relay switches.

6

Relay 2: NO (Normally Open). This contact is connected to C when the relay switches. Availability in the controller depends on the firmware.

7

Relay 2: C (Common). Common connection of the changeover contacts. Availability in the controller depends on the firmware.

8

Relay 2: NC (Normally Closed). This contact is disconnected from C when the relay switches. Availability in the controller depends on the firmware.
