Isolation
An analog circuit is isolated from a digital circuit by a digital integrated circuit/
optocoupler, and the analog channels are isolated from one another by
optocouplers.
Isolation between a digital circuit and the ground: 500 VDC
Isolation between an analog circuit and the ground: 500 VDC
Isolation between an analog circuit and the digital circuit: 500 VDC
Isolation between the 24 VDC and the ground: 500 VDC
