1-1 Features of Analog Output Unit
• The CQM1-DA021 is a SYSMAC CQM1H/CQM1-series Analog Output
Unit that converts digital signals into analog signals.
• The Analog Output Unit has an output signal current range of 0 to 20 mA
and an output signal voltage range of –10 to 10V.
• A single Analog Output Unit allows two-point digital-to-analog conversion.
• It takes only 0.5 ms for two-point digital-to-analog conversion.
1-2 System Configuration
The Analog Output Unit is mounted to the CQM1H/CQM1 CPU as shown in
the following illustration.
• The CQM1-IPS01 Analog Power Supply Unit connects to a single Analog
Output Unit.
• A single Analog Input Unit and single Analog Output Unit can be con-
nected to the CQM1-IPS02 Analog Power Supply Unit. Two Analog Out-
put Units cannot be connected to the CQM1-IPS02 Analog Power Supply
Unit.
• The Analog Output Unit and Analog Power Supply Unit are mounted to
the CPU, just like I/O Units.
• The Analog Output Unit can be mounted either on the left or right of the
Analog Power Supply Unit. The Analog Output Unit must be, however,
adjacent to the Analog Power Supply Unit.
• Refer to 3-1 Settings for the wiring of the Analog Output Unit and Analog
Power Supply Unit.
