Analog Input Modules
Detection of analog process signals
The analog input modules convert analog
process signals, for example pressure, flow or
fill level, linearly into digital values, which are
furtherprocessedbytheQCPU.
앬
Up to 8 channels per module (Q68AD첸)
andupto512channelspersystem(QCPU)
앬
Calculation of average value over the
time or measurement cycles can be con
-
figured
앬
Potential isolation between process and
control by means of an optocoupler is a
standard feature
Channel isolated and high resolution
The analog input modules Q62AD-DGH,
Q64AD-GH, Q66AD-DG and Q68AD-G con
-
vert analog process signals into digital values
with high accuracy . All channels are isolated
between each other and against the external
power supply with high dielectric withstand
voltage for both. This eliminates the need for
external isolation amplifiers.
The Q66AD-DG additionally features the
embedded signal conditioning function, so
that signal converters for 2-wire transmit-
ters are not needed.
앬
Reduced cost for analog I/O that require
channel isolstion
앬
Less space and wiring in the control
panel required
