5.9.2.4. Analog Output

 

The board can output analog voltage on 8 channels. Each channel has 12-bit resolving power in the range of -12V~+12V. The analog voltage value of all 8 channels is transmitted from the MAIN board every 5msec, to renew the output voltage.

The pin allocation of terminal block TBAO for analog output is shown in Table 5-37 below.

 

Table 5‑37 Pin Configuration of Analog Output Terminal Block (TBAI) on Analog Board (BD584)

Number	Name	Use	Remarks
1	AOUT 1	Analog Output Channel 1
2	AOUT 2	Analog Output Channel 2
3	AOUT 3	Analog Output Channel 3
4	AOUT 4	Analog Output Channel 4
5	AOUT 5	Analog Output Channel 5
6	AOUT 6	Analog Output Channel 6
7	AOUT 7	Analog Output Channel 7
8	AOUT 8	Analog Output Channel 8
9	AOUTG	Analog Output Ground
10	AOUTG	Analog Output Ground

 

 

The method of connecting the analog output port is shown in Figure 5.63 below. The example shows the method of connecting to use 4 analog voltage outputs, AOUT1, AOUT3, AOUT5 and AOUT7. Ground of voltage is connected to AOUTG pin #9 or #10. The power used in the analog output circuit uses the insulation separation type DC/DC converter to separate from the internal power of the controller.
