Description 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 for 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 for 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 for time again 3) P1.3: signal being triggered again, reset; disconnect relay, stop timing P2: giving the trigger signal, the for time after shutdown relay CL power relay OP for time; then timing, turn off the relay P3.1: give the trigger signal after the power relay on for time OP, CL shutdown for 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 for time OP, CL shutdown for 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 for time will be canceled, relay stay connected; when the signal disappears, timing OP turn off the relay; over for time, if no signal again, the for time is cleared for Time interval: 0.1 s (minimum) ~ 999 min (maximum) continuously adjustable how to choose the for time interval: in the selection of parameter set interface mode, and press the STOP button to select the for time xxx. if the decimal point is in some place, the for time interval is s-1 999 s xx. x is decimal place is ten, the for time interval is 0.1 s 99.9 s- x. x. x is the decimal point are all on, the for time interval is 1 min-999 min parameter Introduction: OP power over for time, turn off for 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 for key two seconds and then looen enter selection interface mode; by pressing UP, DOWN for 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 for time; CL power off for 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 for key to choose decimal place; choose the for time interval (corresponding for 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 for key to enter; after setting, long press the SET button back on main interface Expansion Function for Key STOP: Activate Relay mode: 1. NO: PO in power over for 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 for 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 for 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.
