●Can use in the workplace environments between -25 to 75 degree Celsius.
●Low power consumption. Supports DC5 to 30V wide input.
●Solid, card-case sized, and metal enclosure.
●Supports installation of 35mm DIN rail.
●Environment-friendly design. Use lead-free solder. Non-use of chromium screw etc.

SI-65A: Japanese model (100V Input AC adapter)
SI-65A-E: World wide model (Wide Input AC adapter )

SI-65A is an interface converter to connect factory automation equipment and analyzers, which only have the serial communication ports for RS-422/485, to LAN.
The built-in Lantronix Xport® on the LAN interface converts RS-422/RS-485 data into LAN protocol (TCP/IP). It also transfers LAN data, controlling RS-485 driver automatically. SI-65A supports a wide range of temperature (-25 to 75°C) and power supply input (DC5 to 30V) compared to SI-65. It has the robust metal body and supports 35mm DIN rail.Therefore, you can use it for factory automation without worry.

■Interface Description

RS-422/485 terminal

6 terminals terminal block, easy to use for wiring at the site

Number Name Full duplex*1 Half duplex*1
I/O direction*2 Description I/O direction*2 Description
1 SD+ Out Send data+ - Cannot used*3
2 SD- Out Send data- - Cannot used*3
3 SD/RD+ In Receive data+ I/O Send/Receive data+
4 SD/RD- In Receive data- I/O Send/Receive data-
5 GND - Signal ground - Signal ground
6 +5V IN - External power input   External power input
*1: Can be switched by the dip switch B.
*2: "Out" means when signal outputted from the converter and "In" means when signal is inputted. Both direction is "I/O".
*3: Do not connect anything when in half duplex mode.

 

LED
LED Description
SD Lights when data comes from LAN to RS-422/485.
SD/RD Lights when data goes RS-422/485 to LAN.
DRIVER ACTIVE Lights when the RS-485 driver of the converter is active.
PWR Lights in green when powered.

■Connection example


In addition to the installation and screwing using the M3 screw holes on the bottom, you can use the optional DIN mounting plate (SI-DIN70) or DIN vertical mounting plate (SI-DIN30S) to mount to a 35mm DIN rail. You can also mount the by using the wall mounting bracket (SI -WM1) with screwing from the front.

■A Useful Tool for Multiple Operation

SILANIOinit is a configuration tool for LINEEYE products embedded WiPort-NR. It is useful and saves time to rewrite the WiPort-NR configuration file (Setup Record) .

[ Functions ]
  • Searches the device on the Network. Displays the MAC address.
  • Reads and saves the configuration (set-up record) of converter.
  • Writes to the set-up record of selected converter.
  • Sets the IP address of selected converter.
