The Mitsubishi Electric FX2N-2DA is a two-channel analog output module for the FX2N series PLC platform. It converts digital values from the PLC CPU into either voltage (0 to 10 VDC or 0 to 5 VDC) or current (4 to 20 mA DC) signals on each of its two output channels. Resolution is 12-bit, giving 2.5 mV per step on the voltage ranges — adequate for driving analog speed references, valve positioners, or chart recorders in process or machine control applications where sub-millivolt granularity is not required.
Power budget and backplane loading
The module draws 30 mA from the 5 VDC rail and 85 mA from the 24 VDC service supply, both sourced from the main unit. This draw must be included in the total backplane power budget for the FX2N rack — exceeding the CPU's internal supply capacity forces use of an external 24 VDC power source. Related I/O points are 8, meaning the module occupies 8 of the available I/O point allocation in the CPU's addressing map, even though only two analog channels are physically present.
Lifecycle status — end-of-life and sourcing path
For a line-down situation or a BOM freeze requiring this exact module, the part is sourced through independent distribution channels.
