ZEM406LP
Daisy Chain SPE Switch
4-port DIN-rail daisy-chain SPE switch. 2× 10BASE-T1L SPE ports and 2× 10/100BASE-TX, with power forwarding up to 70 W between SPE ports. Built-in fail-safe relay preserves chain integrity on local power loss.
ZEM406LP Product BriefPDF · DownloadOverview
- ZEM406LP by Zemfyre Inc. is a 4-port DIN-rail unmanaged switch with 2 ports of Single Pair Ethernet (SPE) 10BASE-T1L and 2 ports of 10/100BASE-TX.
- The switch provides secure 10Mb/s connectivity for up to 1,700m and forwarding of up to 70W of power on the same pair of wires.
- ZEM406LP allows daisy-chaining data and power forwarding on SPE ports when working with ZEM601L switch. Off-the-shelf power source 18-58VDC or 24VAC is capable of powering of up to 40 devices in the chain without use of local power. This line or loop network topology greatly extends the reach for regular 10/100BASE-T(X) based devices not possible before.
- Convenient for field termination industry standard 3.5mm terminal blocks for SPE ports easily wired with either screw terminals or push-in receptacle types.
- ZEM406LP has a bypass relay closing the chain when using local power and the power is out. This way the rest of the network is still completely functional when one node in the chain is out.
- The switch supports configuration over USB interface for advanced features like broadcast storm protection, VLAN settings, ingress/egress limiting, port mirroring, security as well as Cable and Link quality (BER/SNR) diagnostics allowing cable break or short detection and channel quality troubleshooting.
