1-1-1 Analog Input Unit
•
The CQM1-AD041 is a SYSMAC CQM1H/CQM1-series Analog Input Unit that
converts analog signals into digital signals.
•
A single Analog Input Unit converts 4-point analog input into 12-bit digital out-
put. It is possible to reduce the number of input words that the Analog Input Unit
occupies by limiting the number of the Analog Input Unit’s input points to a
maximum of two. Refer to page 81 DIP Switch Functions for details.
•
Converted data is stored in the input word allocated to the Analog Input Unit.
The converted data is used by just reading the contents of the input word. Re-
fer to 3-2-1 Word Allocation for details.
•
The Analog Input Unit has input signal voltage ranges of –10 to 10 V, 0 to 10 V,
and 1 to 5V, any of which can be combined freely with the CQM1-AD041’s input
signal current range of 4 to 20 mA.
•
The Analog Input Unit incorporates a mean value processing function so that it
outputs stable conversion data.
•
The Analog Input Unit incorporates a broken wire detecting function, with
which the Analog Input Unit detects the disconnection of any input wire that
has been connected to the Analog Input Unit given the input range is 4 to 20
mA or 1 to 5 V.
1-1-2 Analog Power Supply Units
•
The CQM1-IPS01 and CQM1-IPS02 are Analog Power Supply Units for the
Analog Input Unit.
•
The CQM1-IPS01 connects to a single Analog Input Unit.
•
The CQM1-IPS02 connects to a maximum of two Analog Input Units.
