Chapter 1 Introduction
1.1 SI-W509 Introduction
Thank you for purchasing our SI-W509 Industrial IoT (IIoT) Remote I/O Module.
SI-W509 Series is a set of data acquisition and control modules 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-W509 modules can communicate with all computers and terminals.
SI-W509 Remote I/O Module has 5 channels of Digital Input and 6 channels of Relay
Output. All digital input channels can be used as 32-bit counters.
The RS-485 network only requires two wires, DATA+ and DATA-. A maximum of
256 SI-W509 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.
