Material: Electrical components.Operating voltage: 6--30V.Trigger Signal Source: High level trigger (3.0V-24V), signal ground and system ground are not common, which can increase the abilit.system anti-interference (possible short circuit also connect with ground common )Output capability: can not control more than DC 30V 5A AC or 220V 5A. Optocoupler isolation: improve anti-interference ability, after setting, memory will stay indefinitely. Warning: the relay contact is passive and electrical production; 1 channel has on/off control function.Notice: Trigger signal source: the high-level trigger signal ground (3.0V-24V) and the system ground are not in common to improve the anti-interference ability of the system. You can also short-circuit the common ground by yourself) If it exceeds 24V, you need to do the heat dissipation by yourself, and it will burn out if there is no heat.Description:Working mode:P1: After the signal is triggered, turn on the relay activation time, then turn it off; during the OP period following the operation:1) P1.1: signal triggering is not effective2) P1.2: signal re-triggering, re-starting3) P1.3: signal is re-starting triggered, reset; disconnect the relay, stop timingP2: giving the trigger signal, the time after the shutdown relay CL power relay OP time; then timing, turn off the relayP3.1: give the trigger signal after the power relay energizing delay, CL cut-off time delay; then run cycle over cycle signal again, stop relay off timer; cycle time (LOP) can be set P3.2: after connection. no need to trigger signal, power relay time to OP, relay CL off time; then the duty cycle above the time cycle (LOP) can be set Q4: keep signal function; if there is no trigger signal, the time will be canceled, the relay remains connected; when the signal disappears, the OP timing turns off the relay; over time, if no signal again, the time is cleared STOP extension function key: Activate relay mode: as the picture. Sleep mode: C-P sleep mode: within 5 minutes no operation; The nixie tube closes the automatic display and a function program D-Normal mode: nixie tube show ever Note: Press and hold the STOP button for 2 seconds to switch from C-P to O-d; The current status will flash and then return to the main interface Size: 6.3*3.8*1.5cm/2.48""*1.50""*0.59""Package Include 1Pc x Cycl Timing Circuit Switch Note: The data are all manual measurement, please allow some 1 - 3cm error, due to the light and display difference, there will be some color difference, depending on the physical object received.
