SI-W709 SERIES USER MANUAL
1.1 SI-W709 Introduction
Thank you for purchasing our SI-W709 Industrial IoT (IIoT) Remote I/O Module.
SI-W709 Series is a set of data acquisition that can be remotely controlled by using
Modbus RTU protocol. The communication interface between the module and the
host is RS-485 serial bus. The baud rate is software programmable and transmission
speeds is up to 115.2 Kbps. SI-Wx09 Series provide Analog-to-Digital,
Digital-to-Analog, Digital Input / Output, Counters and other functions. SI-W709
modules can communicate with all computers and terminals. SI-W709 Remote I/O
Module has 8 channels of Analog Input include Voltage, Current and Thermocouple.
The RS-485 network only requires two wires, DATA+ and DATA-. A maximum of
256 SI-W709 modules can be connected to an RS-485 network, and the transmission
distance can reach up to 4000 feet. For the power requirements, the modules are
designed for standard industrial unregulated 24 VDC Power input; however, they
accept any power unit that supplies power within the range of +9 to +50 VDC.
