Chapter 1 Overview
1.1 Introduction
ADAM-6520 modules are a 5-port industrial-grade 10/100 Mbps Ether-
net switch for fast and cost-efficient network expansion. They connect up
to 5 workstations and auto-detect both 10 and 100 Mbps network speeds.
Moreover, ADAM-6520 modules support auto crossover to provide a
flexible networking environment, connecting to the network via any port.
ADAM-6520 modules provide three methods for mounting in an indus-
trial environment: DIN rail, wall/panel, or piggyback stacking. ADAM-
6520 modules have a flexible input voltage range of +10~30 V
terminal block. ADAM-6520 operates from -10~70° C and ADAM-
6520L from 0~60° C, while ADAM-6520I is from -40 to 85° C. The
above features make ADAM-6520 modules more stable and reliable than
normal Ethernet switches. Thus, ADAM-6520 modules are especially
suitable for industrial environments with Ethernet networking like: semi-
conductor factories, warehouses, conveyer belt systems and more.
1.1.1 High-Speed Transmission
ADAM-6520 modules include a switch controller that automatically
senses transmission speeds (10/100 Mbps). RJ-45 interface also supports
auto-detection, so MDI or MDI-X is automatically selected and a cross-
over cable is not required. All Ethernet ports have memory buffers that
support the store-and-forward mechanism, assuring that data is properly
transmitted.
1.1.2 Flexible Mounting
Due to its versatility and innovative design, ADAM-6520 modules can be
fixed in three ways: DIN rail, panel and piggyback mounting.
1.1.3 Protection for Power Line & Ethernet Port
The power line of ADAM-6520 modules support supports up to 3000
V
surge protection, which secure equipment against unregulated volt-
DC
age and make systems safer and more reliable. Meanwhile, 4000 V
ESD protection for the Ethernet ports makes ADAM-6520 modules (not
including ADAM-6520L) more suitable for harsh environments.
