Question 1

Does this come with an installation manual?

Accepted Answer

I need a manual and cant find a thing online.  Beginning to wonder if I got the wrong unit but seems perfect for my application if I can figure out how to use it.  Please help!

Question 2

Input sourcing or sinking?

Accepted Answer

Sinking

Question 3

Does it need a pc software?  Is there a manual?

Accepted Answer

Yes, we have a electronic manual, here is the link  pan.baidu.com/s/1eRNhn3O
Have the following content of the use of instructions, hope to help you. 
6 point 1a relay 5A current output, with one AD, one DA accuracy is: 0-4095 
Wide supply voltage 10-28VDC 
Dimensions: Length X Width X Height: 66X73X20mm Mounting hole size: 58*65mm Secure with 4 M3 screws. 
This board has one AD and one DA. When two ADs are required, DA can be changed to AD. When D5080 is 1, the DA becomes AD and the AD signal is input from the DOUT pin. 
The input range is 0-3.3V, to be 0-10V, add two resistors (10K.5.1K) to divide. 
Add one statement to the program MOV K1 D5080 to convert DA to AD AD data register is D5032 
Small decision: There is a customer response to download the program is slower, we default download program length is 8000 steps, the actual majority of customers write the program will not exceed 2000 steps, so set up in the GX or WORK2 software, you can put 4 times faster download speed 
The setting method is as follows: After the + sign in front of the parameter in the program data list, the PLC parameter will appear, and then the parameter setting interface will appear after double-clicking the PLC parameter, and the memory capacity can be set from 2000 to 2000 in the parameter setting interface
Module function:
This module is programmable control, can achieve thousands of functions, stable and reliable working performance, built-in watchdog timer circuit, to ensure that the module for a long time to run!!!
Some of the common features are shown as follows:
Turn on the power supply, the relay 1 is closed for N seconds and then disconnect the relay 2 for N seconds.
When the power supply is turned on, the relay 1 is switched off after N seconds, and then the relay 2 is closed for N seconds and then is turned off.
The power supply is switched on, the relay 1, 2 have no action, when a signal or trigger button, relay 1 seconds after N closed off; then 2 seconds after the N relay closed off, until the next trigger, repeat the same action.
Through the signal 1, 2 programming, can be achieved on the relay 1 and 2 arbitrary control.
When the signal 1 has a signal, the relay 1 is closed, the relay 2 is disconnected; when the signal 2 has a signal, the relay 1 is turned off, and the relay 2 is closed.
Can be connected to the sensor signal such as PNP/NPN, the sensor signal programming, to achieve arbitrary control of the relay.
When the signal 1 is triggered, the relay 1 is controlled, and when the signal 2 is triggered, the control relay is controlled by a relay.
Turn on the power supply, control the motor is turning N seconds, and then reverse N seconds, followed by the cycle.
When the signal 1 has a signal, the motor is controlled to rotate; when the signal 2 has a signal, the motor is reversed.
These are just some examples, modules can achieve far more than these functions
*Input high speed pulse C235, C251 and FX1N compatible
*Output relay 1A Type output Rated current 5A Direct drive DC solenoid valve, AC solenoid valve, AC contactor, AC motor, etc..
Precautions for use:
1, The PLC with two programming port. A 232 interface, you can directly use the USB-232 serial port with a computer to download the program directly, a TTL interface.
2, bookPLCBuilt-in1Analog inputADInternal data register (D5030NoD8030)
3, bookPLCBuilt-in1Analog outputDAInternal data register D5101
4, When thePLCNeed to connect with the touch screen or text, can be used to connect 232 programming port, TTL interface can be connected to the company's simple text.
