100% brand new and high quality Features: This product lcd display, very clear, simple and easy to use, powerful, but please read user instructions carefully before using. Product Highlights: 1.Display with LCD two columns, Can display parameters directly; 2.Trigger mode: high and low level,switch quantity.meet most of the needs. 3.Power supply: 6~30V. 4.Parameters can be modified via UART. 5.Stop button to provide emergency stop function. 6.5 minutes without any operation into a low-power state. Any action wake up. 7.OP/CL/LOP params can be modified individually 8.All parameters are automatically saved by power off. Working Mode Introduction(P1~P7) P0: After the signal is triggered, the relay conduction in OP time then disconnects; In the OP time, the signal is invalid. P1: After the signal is triggered, the relay conduction in OP time then disconnects; In the OP time, the signal triggers a new timer. P2: After the signal is triggered, the relay conduction in OP time then disconnects; In the OP time, signal trigger reset timer, relay disconnected and stop timing. P3: After the signal is triggered, the relay disconnects the CL time, and then the relay conduction. P4: After the signal is triggered, the relay conduction the OP time, and then the relay disconnects the CL time, and then loops the above action, gives the signal again in the loop, relays disconnect, stops the timer; and the number of cycles (LOP) can be set; End of cycle, keep relay disconnected; P5: After the signal is triggered, the relay disconnects the CL time , and then the relay conduction the OP time, and then loops the above action, gives the signal again in the loop, relays conduction, stops the timer; and the number of cycles (LOP) can be set; End of cycle, keep relay conduction; P6: No trigger signal after power-on, After the relay conduction OP time, the relay disconnects the CL time, and then loops the above action, signal is invalid in the loop, the number of cycles (LOP) can be set; End of cycle, keep relay disconnected; P6: No trigger signal after power-on, After the relay disconnects the CL time, the relay conduction OP time, and then loops the above action, signal is invalid in the loop, the number of cycles (LOP) can be set; End of cycle, keep relay conduction; P8: Signal hold function: The signal is maintained, the timing is cleared, and the relay conduction; when the signal disappears, the relay disconnects after the timing OP; during the timing, there is another signal and the timing is cleared; P9: Signal hold function: The signal is maintained, the timing is cleared, and the relay disconnected; when the signal disappears, the relay conduction after the timing CL; during the timing, there is another signal and the timing is cleared; (P0~P7) mode, short press the pause button, Start timing if the system is not timed; If the system is already timed, the system pauses the timer, the relay disconnected, flashing "out" to indicate a reminder; P8/P9 mode, The pause button as a trigger signal in the Run interface, Short / Long press fail. Specification: Timing Range: 0.01 sec~9999 min Power Supply: 6V~30V Trigger signal source: High level(3.0V~24.0V), Low level(0.0V ~0.2V), Switch signal Maxmum Output load: DC 30V 5A and AC 220V 5A Static Current: 15mA Operating current: 50mA Service life: more than 100,000 times; working temperature: -40-85C Optocoupler isolation, strong anti-interference ability, industrial grade circuit board, after power set parameters memory forever.
