Communication protocols include general custom protocols and Modbus protocols. Communication baud rates are 2400, 4800, 9600, 19200, 38400 and 115200 (default custom protocol baud rates are 9600, N, 8, 1). 9. It has power supply indicator, eight-way input indicator and eight-way output indicator. 10. Relay contact capacity: 250VAC/10A, 30VDC/10A, maximum switching power 500W per circuit; 11. Relay life: more than 100,000 times, durable; 12. The maximum suction time of the relay is 15 ms and the maximum release time is 5 ms. 13.8-way switch input, all-photoelectric isolation, low input signal voltage is effective (if high level is required, please contact customer service to communicate), can also provide power to the input alone; 14.8 relay output, all photoelectric isolation, using a new original Songle relay control; 15. Use green high-quality WJ/KF128L terminal, withstand 300V, 10A voltage; 16. The input power supply has anti-backconnection protection, over-current protection and continuation protection. There is no need to worry about burning modules and equipment due to improper operation of the power supply. 17. The single chip has EEPROM in it, and no external memory chip is needed. 18. Compiler environment: keil (general 51 environment); 19. Support language: C language or assembly language, can communicate with VB/VC host computer through RS232 or RS485. 20. Using double-sided circuit board design, high-end patch process production; 21. Pass strict testing and stability testing before shipment, please rest assured that customers can use it. Introduction of V interface L Input section VCC: power supply positive terminal; GND: Negative terminal of power supply; A+/B-/GND: RS485 terminal; VIN: Input signal power supply positive pole (default shipment connected with VCC); GIN: Negative pole of input signal power supply (default shipment connected with GND); IN01-IN08: Input signal trigger terminal, low level effective, can be connected to NPN sensor; or switch input, and negative pole short connection is an effective trigger (if high level trigger PNP, please communicate with customer service); L Trigger Requirements If the signal trigger terminal is connected with other modules, the ground wire (power negative pole) between the two modules should be connected together to be effective. If the power supply is shared, a signal line can be connected separately. High level meaning: High level trigger refers to a positive voltage between the signal trigger terminal (IN) and the negative pole of the power supply. When the trigger terminal has a positive voltage or reaches the trigger voltage, it is an effective trigger, usually a trigger mode connected with the positive pole of the power supply and the trigger terminal. Low-level meaning: Low-level trigger refers to the trigger voltage between the signal trigger terminal and the negative pole of the power supply is 0 V, or the voltage at the trigger terminal is lower than that of the positive pole of the power supply. When the voltage at the trigger terminal is low enough to trigger, it is an effective trigger, usually a trigger mode connecting the negative pole of the power supply with the trigger terminal. L Output (Relay Output) NO01-NO08: The relay usually has an open interface, hanging before suction, and short connection with the public end after suction. COM01-COM08: Common end interface of relay, disconnect with normal opening and normal closing end before suction, and disconnect with normal opening and normal closing end after suction. NC01-NC08: The relay usually has a closed-end interface, which is short-connected with the public end before suction and suspended after suction. L Relay Output Connection Method
