100% brand new and high quality Material: Electrical components Color: See pictures Product introduction: 1. Operating voltage: 6--30V 2. Trigger Signal Source: High Level Trigger (3.0 V-24 V), signal ground and system ground are not common, which can increase anti-interference abilit system (short circuit can also connect with a ground common) 3. Output Capacity: can control no more than DC 30V 5A AC or 220 V devices 5A 4. Optocoupler Isolation: improve the anti-interference ability, after the parameter setting, it will memory forever Warning: Relay contact is passive and electricity production; 1 channel has the control function on / off Operation mode: P1: After triggered signal, power relay on time OP, then turn off; within the OP period following operation: 1) P1.1: signal being triggered again is not effective 2) P1.2: signal being triggered again, start time again 3) P1.3: signal being triggered again, reset; disconnect relay, stop timing P2: giving the trigger signal, the time after shutdown relay CL power relay OP time; then timing, turn off the relay P3.1: give the trigger signal after the power relay on time OP, CL shutdown time relay; then operating cycle above cycle gaive signal again, shutdown relay stop timing; cycle times (LOP) can be set P3.2: after connecting. no need to trigger signal, power relay on time OP, CL shutdown time relay; then the operating cycle above timea cycle (LOP) can be set Q4: keeping the function of the signal; if there is no trigger signal, the time will be canceled, relay stay connected; when the signal disappears, timing OP turn off the relay; over time, if no signal again, the time is cleared Time interval: 0.1 s (minimum) ~ 999 min (maximum) continuously adjustable how to choose the time interval: in the selection of parameter set interface mode, and press the STOP button to select the time xxx. if the decimal point is in some place, the time interval is s-1 999 s xx. x is decimal place is ten, the time interval is 0.1 s 99.9 s- x. x. x is the decimal point are all on, the time interval is 1 min-999 min parameter Introduction: OP power over time, turn off time CL, LOP cycle times (1-999 times, --- is unlimited cycle) How to set the parameter: 1. First make sure relay operation mode 2. According to the operaiting relay mode, the main interface (power module will flash current operating mode; standard mode P1.1, then come intot main interface); long press SET key two seconds and then looen enter selection interface mode; by pressing UP, DOWN key to choose the mode setting (P1.1 ~ P4) 3. After selecting the mode, press short SET to set the corresponding parameter, then the parameter you want to set will flash (OP power in time; CL power off time; LOP cycle times, --- is unlimited cycle ); by UP, DOWN to set the parameter value, support long press (increase or decrease quickly) and press slightly (increase or decrease of 1 unit); after setting the parameter value by short press the STOP key to choose decimal place; choose the time interval (corresponding time interval is 0.1 s-999 min); Short press SET to set the current mode next parameter, the process is the same as above 4. After the setting mode parameter, press and hold the SET button then hold the current configuration mode will flash, then go back to the main interface; define success parameter main interface: when the relay does not work, it will show 000 (no decimal point); the operating state relay, the screen has a decimal point Mode Select Interface: press and hold the SET key to enter; after setting, long press the SET button back on main interface Expansion Function Key STOP: Activate Relay mode: 1. NO: PO in power over time, relay can be connected 2. OFF: relay is not allowed to connect, when in the off state in short main interface press the STOP key to achieve turn ON and OFF, current state will flash; then back to the main interface (this function is a function of sudden stop, 1 key to turn off the relay) Sleep Mode: C-P Sleep mode: within 5 minutes, no operation; nixie tube will close auto display, and a function program well The d-Normal Mode: nixie tube show ever Note: Press and hold STOP button for 2 seconds can achieve change from C-P to O-d; Current state will flash and then return to the main interface Size: 6.3*3.8*1.5cm/2.48*1.50*0.59 No retail package Quantity:1Pc Note: Due to the difference between different monitors, the picture may not reflect the actual colorof the item.
