Insulation of Internal Circuit
In the 2302-20, the input circuit and alarm output are insulated
from the CAN bus as shown in the block diagram below. (With-
stand voltage: 1.4 kVAC, 50/60 Hz, Response current: 5 mA, 1
minute)
The CH1 and CH2 terminals are not insulated from each other.
When connecting signals different in potential to these terminals, use
an additional measurement module or insulate the signals externally
before connection to the terminals. This will prevent module errors and
malfunction.
