Description

This analog input module receives signals with standardized values of ±10 V.
The module works synchronously with the internal data bus for all
couplers/controllers used. When the module is connected to the Profibus
Fieldbus Coupler 750-303, the (fieldbus) network wide acquisition of
measured values can also be done synchronously. Triggering is done via this
special Profibus-DP/FMS (12 Mbaud) coupler. After receiving the command
"Global Control Command", the acquisition of measured values is initiated by
the coupler. A delay of one cycle is to be expected when scaling the measured
values. Sampling cycles ≥ 1 ms can be achieved.
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 (sreen) 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).
