made to tap into your existing arcade power supply, if you don't have a power supply i can sell you one, will not work without power supply,simple to install, no sound, part #dseff 1. Operating voltage: 6--30V2. Trigger Signal Source: High Level Trigger (3.0 V-24 V), signal ground and system ground are not common, which can increase anti-interference abilitsystem (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 5A4. Optocoupler Isolation: improve the anti-interference ability, after the parameter setting, it will memory foreverWarning: Relay contact is passive and electricity production; 1 channel has the control function on / offOperation 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 effective2) P1.2: signal being triggered again, start time again3) P1.3: signal being triggered again, reset; disconnect relay, stop timingP2: giving the trigger signal, the time after shutdown relay CL power relay OP time; then timing, turn off the relayP3.1: 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 setP3.2: 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 setQ4: 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 clearedTime interval:0.1 s (minimum) ~ 999 min (maximum) continuously adjustablehow to choose the time interval:in the selection of parameter set interface mode, and press the STOP button to select the timexxx. if the decimal point is in some place, the time interval is s-1 999 sxx. 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 minparameter 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 mode2. 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 above4. 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 parametermain interface: when the relay does not work, it will show "000" (no decimal point); the operating state relay, the screen has a decimal pointMode Select Interface: press and hold the SET key to enter; after setting, long press the SET button back on main interfaceExpansion Function Key STOP:Activate Relay mode:1. NO: PO in power over time, relay can be connected2. OFF: relay is not allowed to connect, when in the off statein 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 wellThe d-Normal Mode: nixie tube show everNote: 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 interfaceSize: 6.3*3.8*1.5cm/2.48"*1.50"*0.59" Brand: bruce1arcadeservice
