Option module type ”2 optocoupler outputs”.
Function:
This affordable module offers 2 pieces of digital outputs
for example simple ON/OFF control via SMS.
The 2 digital outputs are controlled identically, as the 2
relay outputs available on option module I / II and
therefor are in the same way controlled via SMS and
status can be checked via SMS.
See page 22: SMS for activating and deactivating the
relay outputs of the FA20.
Each digital output is associated with a green LED that
indicates the current status of the output. Light in the
LED means output is active (closed loop).
Specification:
These are 2 electrically isolated optocoupler outputs.
Max. applied voltage is 27Vdc (open loop).
Max. power is 27mAdc (closed loop).
Connection guide:
Digital output no. 1 is the two terminals on the left called (OUT1) and the digital output no. 2 is
the two terminals on the right called (OUT2).
Correct polarity is shown in applied plus and minus symbols (plus on the left and minus to
right).
NOTE: By improper polarity the optocoupler output will open permanently and proper
operation will normally not occur. Incorrect polarity can lead to permanent damage –
depending on the connected voltage.
