ANALOG AND
DIGITAL INPUTS
AND OUTPUTS
The following table shows the different options for the analog and digital IOs
.
>
Analog functions for AIO1 not yet implemented, but the inputs can be used for digital signals
.
>
Only one IO can be configured for same function, except for door switch. In case of double configuration
an alarm will be activated
.
>
If a short-circuit is made of the 12V supply, the controller will disable the 12V supply, all digital and
analog ports, including display. The controller, temperature sensors, relays and the Modbus connection
will still be active
.
>
If the 12V supply is overloaded, the controller will disable the 12V for 10 seconds, then enable it for 1
seconds. This will continue until the overload disappears
.
*Switch: Contact with 2 stable positions (open/closed).
**Push-button: Contact with 1 stable position (open) and only closed when pushed.
