5.4.3 Insulation of Internal Circuit
In the 2304-21, 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 measuring two measurement points having a potential differ-
ence, equalize the ground level potential of these two points, or use
another 2304-21 Module, since measurements may be adversely
affected.
