Crocodile Alligator Clip 50 mm- Red A clip (also alligator clip or spring clip) is a simple mechanical device for creating a temporary electrical connection and is named for its resemblance to an alligator or crocodile's jaws. Functioning much like a spring-loaded clothespin, the clips tapered, serrated jaws are forced together by a spring to grip an object. When manufactured for electronics testing and evaluation, one jaw of the clip is typically permanently crimped or soldered to a wire or is bent to form the inner tubular contact of a15 mm ~ 4 mm female banana jack, enabling the quick non-permanent connection between a circuit under test and laboratory equipment or to another electrical circuit. The clip is typically covered by a plastic shroud or "boot" to prevent accidental short-circuits. Applications: Small versions, ranging in size from 15 mm – 40 mm in length, are used in electrical laboratory work and school, and college labs. Large versions of these clips, called automotive clips or battery clamps, are made of solid SS for low electrical resistance, are used with thick insulated SS cables to make connections between automobile batteries.

The clip is designed for creating temporary electrical connections and is commonly used in electronics testing and evaluation.

DB-9 Male Right Angle Connector Designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard, so that multiple companies could design them into their products. DB9 connectors are commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also, they are used on DB9 cable assemblies for data connectivity. DB9 is used in many legacy devices that use the DB9 interface for serial communication. The connector module is a male right-angled connector with solder cups. Best suitable for mounting on circuit board. Connecting cables in tight spaces can be a problem in many applications. These low profile right angle D-Sub adapters solve this problem by allowing cables to be connected at a 90-degree angle. Three versions are available for each connector size allowing for cables to exit in opposite directions. Adapters are male to female, fully shielded and are over-molded with gray PVC. Mating hardware is reversible allowing for use in virtually any application. Applications: D-Sub confined space Enclosure applications OEM applications Serial data transmission Data networks Instrument control Device management

With emergency stop function (“stop” button) and reverse polarity protection which can avoid burning by reverse connection. It is 6-30V 1-Channel Delay Power Relay Module with Onboard Adjustable Timing Cycle Switches with Digital LED display It is mostly used in Home Automation Delay Timer Control Switch Module Timer Controller. The Module operates at Operating voltage range of 6-30V, also it supports micro USB 5.0V power supply. Output capability: Can control the device within DC 30V 5A or AC 220V 5A. It can be applied to many fields as there is a wide range of application. What is Relay ? Explained in simple terms. Operation Mode: P1: Trigger signal, the relay is on “OP” time, and then disconnect; Within the “OP” time, proceed as follows: P1.1: the signal is triggered again, invalid P1.2: the signal is triggered again, re-clocking P1.3: Signal has triggered again, the relay is disconnected, stop the clock; P-2: Trigger signal, after the “CL” time is off, the “OP” time is on. When the timing is completed, the replay will be disconnected; P3.1: Trigger signal, after the “OP” time is on, the “CL” time is off, then cycle the above actions. If trigger signal within the loop, the relay will be disconnected and stop the clock. The number of cycles ( “LOP “) can be set. P3.2: No need to trigger the signal after powering up, the “OP” time is on, the “CL” time is off, then cycle the above actions; The number of cycles ( “LOP “) can be set. P-4: Signal holding function. If the signal is triggered, timing is cleared, the relay remains on; when the signal disappears, the relay will be off when the “OP” time is over; if another signal is triggered during timing, timing will be cleared. How to choose the time interval: parameter Introduction: OP power over time, turn off time CL, LOP cycle times (1-999 times, “—” is unlimited cycle) In the selection of parameter set interface mode, and press the STOP button to select the time. (1)xxx. if the decimal point is in some place, the time interval is s-1 999 s (2)xx. x is the decimal place is ten, the time interval is 0.1 s 99.9 s- (3)x. x. x is the decimal point are all on, the time interval is 1 min-999 min How to set the parameter: First, make sure relay operation mode According to the operating relay mode, the main interface (power module will flash current operating mode; standard mode P1.1, then come into the main interface); long press SET key two seconds and then choose and enter selection interface mode; by pressing UP, DOWN key to choose the mode setting  (P1.1 ~ P4) 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 choosing 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 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 the main interface Activate Relay Mode: NO: PO in power over time, the relay can be connected 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, the current state will flash; then back to the main interface (this function is a function of a 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 Note: Press and hold the 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 The relay contact is passive and electricity production; 1 channel has the control function on / off
