Relay outputs
Please refer to the ScriptEasy manual for more information on I/O management.
8 SPDT relays with one com input (common) and two outputs: NC (normally closed) and NO (normally opened).
➢
When the relay is not in use, com is linked to the NC output.
➢
When the relay is activated, com is linked to the NO output.
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.
◼
Relay output external connection diagram:
External connections on SUB-D 25pts male connector located at the end of the board.
➢
Each circuit can support 5 A between -50 V and +50 V.
➢
A +12 V power supply with a max current of 250 mA is available on pin 13.
Ground for the 12 V power supply is available on the ground of the unit.
