This circuit uses several cheap transistors and two relays to make the bus's twitch signal and turn signal comprehensively control the tail lights; both tail lights are on when braking, and only one tail light is on when turning. The turn signal causes the tail light to turn on twice per second. When turning, C1 and C2 charge to the peak pressure of the turning signal. The size of the capacitor should be such that the relay can pull in and out during the interval between lamp flashes. If the capacitor is selected too large, the brake signal will not illuminate the tail light immediately after the turn signal is removed. This circuit is designed for a new type of car. In order to ensure safety, this kind of car needs to separate the turn signal and the brake signal.
100M 8+2 port passive POE Switch for IP camera
STD-POE5203-10 supports data and power transmission through CAT.5 cables at the same time. And 8+2 port support fast connecting at 100/1000Mbps. It also supports long transmission distance at 250 meters both for power and data, therefore, it saves cost for the project that requiring long distance transmission through extender, fiber and coaxial cable etc. It reduces line losses effectively though 8-core cable supplying power same time. Max power for each port is 30W, which is for IP Camera and POE wirelessaccess point etc.
Features:
REVERSE POE TECHNOLOGY:8 Port 10/100 Reverse POE switch which has latest generation of fast Ethernet reverse POE switching technology. It contains 7*10/100 base T Reverse Poe ports (RPOE),1*10/100 Base date Uplink Port&12V DC out for Powering ONU.
Supports Auto-Negotiation: Each of the ports automatically detect whether connected network devices are running at 10Mbps or 100Mbps and half-duplex or full-duplex mode, and adjusts the speed and mode accordingly ensuring easy and hassle-free operation.
Supports Non-blocking Wire Speed: The switch forwards and receives traffic seamlessly with its Non-blocking wire- speed. Every port of the Switch supports speeds up to 200Mbps in full-duplex mode simultaneously, providing full wire speed to connected devices and allowing you to run a high speed network smoothly.
Cascading support: switches can be cascaded for more users per Building (Up to 1 Main+3 switches )
Port base Isolation u/Hardware VLAN: The feature of Port Isolation is implemented in this unit where in the Ethernet Date of the Uplink Port can be transferred to any of the Downlink ports but the individual Downlink ports cannot communicate with each other.
Over voltage Protection:
Over voltage Protection is provided on each date port to eliminate damage due to connection of higher voltage(Higher than 24V DC. Up to 80V DC). By mistake if user connect more than 24V POE injector then switch will goes on power off mode and will start working again once this high voltage source is removed.
Over current Protection: We have provided over current protection on each port to prevent damage to the switch in case of high current flowing due to any reason. This is provided using Resettable Fuse to facilitate easy maintenance and avoiding frequent change of blown fuse.
Product Application:
7*10/100 Base T Reverse POE Ports(RPOE) & 1*10/100 Base T Uplink Port & 12V DC Power out for Powering ONU
