Connection for Battery Monitoring
Both reference inputs (minus inputs) of each
IB IL 24 AI 2/SF-230 terminal are connected with each other. If signal sources are
connected in series, wrong connections can lead to a short circuit of individual signal
sources.

Connection for battery monitoring
Because of the single-ended inputs, the
following connections are necessary:
Connect the reference input of a terminal
between two voltage sources.
Channel 1 measures the first voltage source
with opposite polarity. The measured value must
be adapted in the control system to the polarity.
Channel 2 measures the second voltage source
with correct polarity.
Configure the terminal to bipolar (±10 V).
