This post guides you in how to use the Relay Output Module.
Relay Output Module, Take a look at the link to check the module out Relay Output Module
This module is designed to use 12Vdc digital output to activate relays. The module consists of 10 relays and 10 inputs interconnected between them. When the input I0.X detects a HIGH value, the corresponding relay output RX will close the circuit, X being any value between 0 and 9. This process is completely implemented by hardware. There is no software that interacts with this Relay Outputs Module.
*The output current is divided in all 10 relays. If all 10 relays are working at the same time, the output current per relay will be 0,08A.
When looking at the schematic, there are some things that must be taken into consideration.
The left part of this module is for the relay outputs. The supply that will be in the Relays connectors will be the one that is implemented in the VCOM(+) and COM(-). All VCOM(+) amd COM(-) are interconnected. This means that there is only 1 VCOM(+) and 1 COM(-) different signals. The right part shows the inputs. The inputs are all referenced to the same GND connectors.
