Serial Output/Input Control Card

Serial Output/Input Control Card

We are one of the most trusted Suppliers of Serial Output/Input Control Card. This STM8S microcontroller based control card can be used to switch ON & OFF 17 relays via serial communication (RS232 or UART TTL). It can also read the status of 8 digital inputs. The relay output status & digital input status is continuously sent out as RS232 data string. It operates in 9600BPS, 8-N-1 mode. This control card can be controlled via our weighing scale PCB or via PC. This board is very useful for industrial control & automation. Simple control commands is sent to card to switch ON & OFF the Controllerâs output pins. For example sending ASCII character âAâ will make the connector PIN marked âAâ on the PCB to go high(5 volts) & sending ASCII character âaâ will make the same pin to go low(0 volts). Sending ASCII âBâ will switch ON the pin marked âBâ on the PCB & so on. You can control 17 pins from A to Q & read 8 pins from R to Y.
