The JetHome ES1-AC Ethernet switch is designed for use in home automation systems and serves to connect devices (controllers) with an Ethernet interface and supporting the power supply function using Passive PoE technology into a local network. The DIN-rail housing allows the switch to be conveniently placed in a switchboard close to other controllers.
The main function of the device is to combine several nodes (devices) within one segment of the Ethernet network with a speed of up to 100 Mbps. The physical layer can be Category 5 cable with two or four twisted pairs. 8P8C (RJ45) connectors are used to connect the cable. Pins 1, 2 and 3, 6 of the connector are used for data transmission.
Ethernet Switch Features:
WARNING! Only devices that support PoE power can be connected to the switch. Do not connect computers, laptops and other household devices to the ports “ETHERNET 2” - “ETHERNET 5” in order to avoid damage.
The switch has a built-in AC/DC voltage converter with AC input voltage from 110V to 240V and DC output voltage of 24V. The output power of the built-in converter is 30W. Power is supplied to the “AC IN” terminal of the switch.
The switch can be powered from an external DC source using Passive PoE technology through the “ETHERNET 1”/“POE IN” port. Pins 4, 5 (+) and 7, 8 (-) of the “ETHERNET 1”/“POE IN” port are used for power. Rated supply voltage range - from 12V to 48V, maximum supply voltage range - from 12V to 56V.
The built-in AC/DC voltage converter has a higher priority and when the controller is connected to an AC source, the controller and external devices will be powered from the built-in 24V converter, regardless of whether voltage is applied to the “POE IN” input.
The switch can power up to 4 devices connected to the ports “ETHERNET 2” - “ETHERNET 5” (“POE OUT”) using Passive PoE technology: pins 4, 5 (+) and 7, 8 (-) of the ports are used .
When the switch is powered by AC power, the output voltage at the “POE OUT” ports is 24V. The maximum total current supplied to consumers connected to the “POE OUT” ports and the “DC OUT” terminal in this case is 1.3A (see p. Overload protection).
When the switch is powered from the “ETHERNET 1” (“POE IN”) port, the output voltage at the “POE OUT” ports will correspond to the input voltage “POE IN”, and the maximum total current given to consumers connected to the “POE OUT” ports in this case is 2.5A (see p. Overload protection).
The switch has the function of protection against exceeding the maximum output current given to consumers:
The switch has a power backup function using an external 12V battery. Lead-acid batteries with a capacity of 1.2 Ah can be used for power backup. The battery is connected to a dedicated controller terminal “BATTERY 12V”. If the external power supply fails, the switch and devices connected to it will be powered by a battery with an output voltage of 12V.
The switch has a built-in charger that charges the connected battery. Depending on the capacity of the battery used, you can set the maximum charging current of the charger. The maximum charging current is set by a jumper (jumper) on the charger board and can be set to one of three values:
By default, the jumper is set to 0.3A. To change the value of the maximum charging current, it is necessary to open the switch housing and move the jumper (jumper) to the appropriate position (see the marking on the charger board).
The switch has a battery monitoring function. When the voltage on the external battery is low (11V or less), the red “BATTERY LOW” indicator on the front panel of the switch lights up and the “BATTERY LOW” relay contacts connected to the external terminal close.
To protect the battery from deep discharge at a voltage of 10.5V or less, the battery is switched off. The battery is connected after charging up to 12V.
WARNING! The battery is charged only from the AC/DC converter built into the switch when the switch is powered from the AC mains. When the switch is powered from the “POE IN” input, the battery is not charged. Therefore, to use the battery backup function, it is recommended that the controller be powered by AC power. To operate from a battery, external devices powered by the switch must support a supply voltage range of 10V.
The switch has the following LEDs that display the status of the switch:
On the front panel:
On the Ethernet connectors:
Коммутатор имеет два релейных выхода “сухой контакт”, дублирующие индикаторы на лицевой панели коммутатора:
Максимальный коммутируемый ток - 1А.
Коммутатор может быть установлен в шкафу электрооборудования или другом месте, в котором должна быть обеспечена защита коммутатора от попадания влаги, грязи и посторонних предметов, а также отсутствие вибрации. Для лучшего охлаждения внутренних элементов коммутатора корпус коммутатора необходимо устанавливать в вертикальном положении.
Для установки коммутатора следует:
Для демонтажа коммутатора с DIN-рейки следует:
Для обеспечения надежности электрических соединений рекомендуется использовать медные многожильные кабели. Концы кабелей следует зачистить, потом залудить их или использовать кабельные наконечники. Жилы кабелей следует зачищать так, чтобы их оголенные концы после подключения к коммутатору не выступали за пределы клеммника.
