ZLAN5143I make isolation design for power supply, using 3000V isolation power, as
adding 3000V AC voltage between input power line and shell, the current leakage into
ZLAN5143I is less than 5 mA. The isolation has been through strict test.
Provide shell earth terminal, can release lightning current into the earth and protect
the products.
The RS485 of ZLAN5143I can drive 256 load capacity, compared to the product
driving 32 loads, it can achieve the ability of monitoring more equipment to save cost.
ZLAN5143I has three interface types: RS232/485/422. The input voltage can provide
DC Q2. 1 jack or terminal type, the input voltage is 18~36V (can be customized 12V).
It can be equipped with guide installation accessories.
ZLAN5143I has data transparent transmission function for TCP to RS232/485/422,
also has the storage type Modbus gateway function, and the storage type means
5143I can auto-collect data of Modbus RTU devices and store, so the Ethernet end
collect data just directly read from inside 5143I, it greatly accelerate the data collecting
speed of Ethernet end.
The typical application connection is shown in figure 2. The original serial devices
connect to ZLAN5143I, then connect ZLAN5143I to network through cable. After if
using “Transparent Transmission” way: any data sent by serial devices will be
transparently transmitted to PC assigned by ZLAN5143I, and the data PC sending to
ZLAN5143I through network also will be transparently transmitted to serial devices. If
using “Modbus TCP Gateway” way: Modbus TCP software of host computer can
realize the collecting of Modbus RTU devices through 5143I.
