ABB Electrical 1SBL321001R8010 230-240V 3-Phase Auxiliary Contactor

Model Type: A40-30-10 220-230V 50Hz / 230-240V 60Hz Electrical 1SBL321001R8010 230-240V 3-Phase Auxiliary Contactor

Characteristics

Ethernet ports are labeled 1 through 4 for documentation purposes.

SDSL ports are connected via the backplane. There are no specific uplink ports.

All ports are functionally identical.

The link and speed status of each Ethernet port and SDSL port is indicated by status indicators (see “Connectors and Indicators”).

The switch learns Ethernet addresses by analyzing incoming frames and stores them in a lookup table (up to 2048 entries),

used to forward frames only to the correct port. If the frame is

widecast or multicast, or the destination address is not found in the lookup table, the received frame is forwarded to the correct port.

If an entry in the lookup table is not refreshed by an incoming frame with a specific source address

then it is aged out for a maximum of 304 seconds.

Maximum 304 seconds (default, configurable).

For IEEE 802.1Q VLAN frames, the switch can be configured in VLAN or transparent mode. In transparent mode

the switch does not change any frames or frame TAGs; in VLAN

mode, the switch can be configured to support a variety of applications, such as

trunking or access ports.

The switch will support quality of service if it uses an IEEE 802.1p-compliant frame format.

The switch can support quality of service if the frame format is IEEE 802.1p compliant. The switch can divide frames

into up to four queues, which can be configured as priority queues or weighted fair queues.

The switch uses a 5 V supply voltage, which can be set as the internal RTU power supply or via a jumper.

It can be set to internal RTU power or external power via jumpers.

The components themselves, the Ethernet ports, as well as the SDSL

connections and RS232 interfaces are hot-swappable.

Use the 560NMS24 unit as a repeater for longer distance transmission.
