Mitsubishi Electric FX2N-2DA User Manual page 2

1. INTRODUCTION
The FX -2DA type analog output block (hereafter referred to as the FX
2N
digital value of 12 bits into an analog output of two points (voltage and current output), and to forward the
values to the Programmable Controller (hereafter referred to as a PLC).
FX -2DA can connected to the FX
2N
Programmable Controllers.
1) The analog output is selected from the voltage or current output by the method of connecting wires.
At this time, assume setting to be two channels common analog output.
2) The two analog output channels can accept outputs of 0 to 10V DC, 0 to 5V DC, or 4 to 20mA.
(A mixture of voltage/current output is possible.)
3) Resolution is 2.5mV (0 to 10V DC) and 4µA(4 to 20mA).
4) The digital to analog conversion characteristics can be adjusted.
5) The block occupies 8 I/O points which can be allocated from either the inputs or outputs.
6) The data transfer with the PLC uses the FROM/TO instructions.
FX /FX series PLC can use direct specification of buffer memory.

However the following limitation exists when the undermentioned special function blocks are connected.
FX : Main unit and powered extension units of 32 points I/O or less. Consumption current available
2N
for undermentioned special function blocks ≤ 190mA
FX : Main unit and powered extension units of I/O 48 points or more. Consumption current available
2N
for undermentioned special function blocks ≤ 300mA
FX : Up to 4 undermentioned special function blocks can be connected regardless of the system I/O.
2NC
FX : Main unit and powered extension units. Up to 2 undermentioned special function blocks can be
0N/1N
connected regardless of the system I/O.
Consumption current of 24V DC for one unit
The consumption of the above units is to be subtracted from the service power supply of the host
PLC.
3) The blocks occupies 8 I/O points (the 8 points can be allocated from either inputs or outputs).
4) FX -2DA consumes 5V DC 30mA.
2N
The total 5V consumption of all special function blocks connected to either a main unit or an
extension unit must not exceed the 5V source capacity of the system.
