DROK Time Delay Relay ModuleParameter: Operating voltage: DC 6-30V Trigger signal: high level trigger (3.0V-24V), low level trigger (0.0V-0.2V), switching value control (passive switch). Output capacity: can control devices within DC 30V/10A or AC 220V/5A. Timing range: 0.01s-9999mins Working current: 50mA Quiescent current: 15mA Service life: more than 100,000 times Working temperature: -40~85℃ Dimension: 7.1*3.9*2.5cmFeatures: 1. With clear LCD screen displays relay status, current working mode, timing status & time. 2. Support UART data uploading and parameter setting. 3. With pause button, support one-button pause. 4. With reverse connection protection, won't burn out if wire are connected reversely. 5. With sleep mode, after enabling, if there is no any operation, the screen backlight will be automatically turned off. Press any key can wake it up. 6. Able to set different OP, CL, LOP parameters which are independent and saved separately; 7. Support viewing currently set parameters without affecting system operation. 8. With power off storage function, all parameters will be automatically saved when power off.Note: There is no trigger cable or connector included, need to be purchased separately.Package Included: 2x Delay Relay Module
