Analog Output Units

Output Status after
Communications Error
Pins 8 and 9 of the DIP switch determine the status of the outputs after a com-
munications error occurs in DeviceNet or I/O Unit interface communications.
When the clear to minimum, clear to maximum, or clear to 0 V setting is used,
the output data is as shown in the following table.
Converted Data
Output the converted data to the Master as shown in the following diagram.
When a negative voltage is to be output, specify the conversion data as the
two’s complement. To obtain a two’s complement from an absolute value, the
NEG instruction is useful.
Conversion Time
The conversion data is refreshed every 4 ms for all 4 points.
Dimensions
Note The vertical center of the Unit is 4.9 mm lower than the center of the DIN
track. The Unit therefore extends downward 41.4 mm (including the mounting
hook) from the DIN track center.
