Relay communication: Multi-unit network 485 communication, based on MBDBUS-RTU protocol, the default communication address ID is 1, and users can modify the address by themselves through instructions Note: IN1 - IN4 are connected to the switch to read the switch state through 485, not to control the relay output through the input. The switch status of IN1-IN4 needs to be read every time the computer inquires about the switch status, and cannot actively send data to the 485. Note: IN1-IN4 cannot be connected to 220V (some buyers will make this mistake) The wiring is as follows: IN1 - GND (default is high level, low level after the switch is turned on) The computer sends an instruction to read the switch state. IN2 - GND (default is high level, low level after the switch is turned on) The computer sends an instruction to read the switch state. IN3 - GND (default is high level, low level after the switch is turned on) The computer sends an instruction to read the switch state. IN4 - GND (default is high level, low level after the switch is turned on) The computer sends an instruction to read the switch state. Size: 76mm*67mm*17.5mm Signal access terminal voltage: 3v-30v Strong current control terminal voltage: 220     |
