Relay outputs
This module provides 8 bistable relays. Each relay has one com input (common) and two
outputs: NC (normally closed) and NO (normally opened).
ys. Each relay has one com input (common) and two
outputs: NC (normally closed) and NO (normally opened).
Schematic diagram:
¾
When the relay is not in use, com is linked to the NC output.
¾
When the relay is activated, com is linked to the NO output.
Note: If your unit reboots, com is then linked to the NC output.
Practical examples:
1. The relay can be used like an on-off switch to make a contact between the common and one
of the outputs (NC or NO).
2. It is also possible to connect a power supply to the common (for example the +12 V power
supply available on pin 13) and to switch this power supply between the NC and the NO
output.
