5.8.2.2. Digital Output

 

Figure 5.47 below shows the pin composition of the terminal block (TBO1~8) for digital output. Each terminal block can be connected to the common power for 8 input signals, and can use a different power supply than the common power of the terminal block for other input.

Table 5‑31 Pin Configuration of Digital Output Terminal Block (TBOn*) on Expansion Public IO Board (BD583)

Pin Number	Signal Name	Signal Description
9	COMn*	COMMON power (Ground DC24V or DC24V)
8	DOn*1	1st output of nth public output signal port of user
7	DOn*2	2nd output of nth public output signal port of user
6	DOn*3	3rd output of nth public output signal port of user
5	DOn*4	4th output of nth public output signal port of user
4	DOn*5	5th output of nth public output signal port of user
3	DOn*6	6th output of nth public output signal port of user
2	DOn*7	7th output of nth public output signal port of user
1	DOn*8	8th output of nth public output signal port of user

Note *) Terminal Block Number n = 1~8 (Ex, TBO1, TBO2, TBO3, TBO4)

 

The electric specification of each output signal is as follows.

 

n Output component: Photo MOSFET (TBO1~4), relay (TBO5~8)

 

n Rated output

Photo MOSFET 125mA (Continuous load current) / 24V DC

Relay: 3A / DC 24V, AC250V

 

n Common power: Ground 24VDC or 24VDC

 

The user connects the output signal through the method shown in Figure 5.48 below. First, connect the common signal (COMMON) to the Expansion Public IO Board (BD583), and then connect each signal to the output pin according to the usage. The power can be grouped by 8 output signals, and can be applied differently by port.
