Port configuration: There are eight ports, which are 10/100Base-TX.
Design features:
Din-rail mounting modules are designed to meet the needs of real-time industrial control solutions.
Supports 802.3u, 802.3U, and 802.x compatibility, 10/100 base copper tape automatic negotiation, and full/half duplex automatic negotiation.
It has 100Mbps FX-uplink port and HP-MDIX automatic sensing function.
Leds indicate the status of link presence, activity, duplex, and speed ports (each LED has two colors), and can also indicate power status.
Minimum 256KB buffer with 4K Media Access Control (MAC) address, as well as redundant power input.
Installation and configuration: Use DIN rail to mount the switch on the control system panel for new installation, connect copper and/or optical cables according to the redundancy and requirements of the system, and connect the switch to the 28V DC of the distribution board. It uses the RJ-45 connector to support multiple inserts and removers, has an expected service life of 200 insert/remove cycles, and can withstand torsional pressure applied to the connecting assembly along any shaft, as well as static tension caused by cable weight and cable dressings.
