14.3. Alarm outputs
Contacts and outputs are available on the rear side connector (A1 / A2), B and C.
The A1/A2 contact is a dry contact without any potential (24 V /100 mA).
The B and C outputs are TTL 5 V outputs.
When the appliance is voltage free, the A1/A2 contact is open and the B and C outputs have a 5 k 
impedance.

Indication of internal events to the outside and the recorder (triggers on the analogical or logical
channels, status of the printing block )
See chapter Use , paragraph Setup key.
14.4. Power supply output
There is a +12 V power supply output limited to 0.1 A on the pin #23 of the connector.
The grounding of this power supply is the mechanical grounding.
So, you can use this output to provide power to a sensor or an electronic circuit in order to manage
logical inputs.
The 12V supply may disappear in case of overload (> 0.1 A).
You should then turn off the appliance for a few minutes before turning it on again.
