Specification: Item Type: Control Board Material: PCB Working Current: Digital Tube OFF (Power Saving State): Relay OFF 6MA, Relay ON 35MA Digital Tube ON (Working State): Relay OFF 29MA, Relay ON 56MA Three States: Working State, Power Saving State, Setting State Input Port: Optocoupler isolation input, compatible with NPN, PNP input (5-24V switch signal) Output port: 10A relay NO COM NC three ports There are three wiring methods for the trigger signal input terminal: 1 No external signal source required 2 Trigger with NPN signal source 3 Trigger with PNP source Working status: power on working status, F00-F05 mode displays the remaining time, F10-F15 mode displays the remaining time and pulse count value. Note: When the remaining time is greater than four digits, short press the "OK" key to scroll and display the remaining time once. Setting status: short press ''SET'' key to enter setting status, then short press ''SET'' to switch parameters, short press ''++'', ''--'' to modify parameters. Short press the "OK" key to save the parameters and exit the setting state. Note: After setting the parameters, it must be powered on again. Query status: without modifying the parameter setting status, short press the "SET" button to enter the query status, then press "SET" to switch parameters, and short press the "OK" button to exit the query status Power saving state: The working state of the digital tube is off. In this state, the digital tube does not display, and other functions work normally. Press and hold the "OK" button for 5 seconds to enter the power saving state, and long press the "OK" button for 5 seconds to exit the power saving state. 1 In the power saving state, you can still enter the setting and query state, and automatically enter the power-saving state after 20 seconds of no key operation. 2 After turning it on again, the digital tube displays for 20 seconds, how to turn off the digital tube. Factory setting: Press and hold the "++" and "--" keys at the same time for 3 seconds to restore the factory settings and turn off the display of the digital tube. Run with default parameters after reboot. Note: After setting the parameters, it must be powered on again. Exception handling: 1 If you encounter inexplicable problems, please power on again (this is because there is no restart after setting parameters) 2 If the problem still cannot be solved after powering on again, please long press the ''++'' and "--" keys at the same time for 3 seconds to restore the factory settings. then reboot.
