Description

This analog input module receives signals with standardized values of ±10 V.
The module has two differential input channels and can receive differential
signals via the connections +AI 1 and -AI 1 or +AI 2 and -AI 2.
The Shield (screen) is directly connected to the DIN rail. A capacitive
connection is made automatically when snapped onto the DIN rail.
The input signal of each channel is electrically isolated and will be transmitted
with a resolution of 14 bits(13 bits + sign bit).
The operational readiness and trouble-free internal data bus communication of
the channels are indicated via a green Function LED. Overrange or underflow
of the measuring range is indicated via a red error LED.
Any configuration of the input modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The voltage supply is done via system voltage.
