Here, you can connect 8 input signals (0…7), each bipolar and galvanically isolated. Each channel is connected using a two-wire connection. Due to the reverse polarity protection, the measurement signal is indicated logically correctly even if the connection is reversed.
Circuit diagram
The input circuit diagram of one channel is shown here as an example.
