The Semaphore G3 Remote I/O Module enables remote monitoring and control in a broad range of
applications. It can be operated as remote I/O or in a back-to-back mode. Remote I/O modes
support Modbus and Kingfisher protocols, which readily drop into practically all SCADA systems. In back-to-back mode, two G3 Modules make up a system that operates as a wire replacement, which is ideal for secure I/O transfer in any application. Since it supports Modbus RTU slave, the G3 can readily be added to a broad array of existing PLCs, RTUs, and SCADA HMIs using RS-232 or RS-485, or
wireless with the proven Maxstream spread spectrum radio.
Compact package, small footprint, rugged enclosure readily accommodated in instrument cabinets; Color organic light-emitting diode (OLED) screen displays system parameters and status information in real time and in easy-to-read, high-contrast, 16-bit color; Onboard I/O includes eight I/O points in an effective mixture: 2 AI, 2 DI, 2 AO, and 2 DO. Analog I/O points can operate as discrete points, if required. A pluggable terminal block eases wiring and installation; Built-in logic functions allow basic control of inputs and outputs
Serial or wireless communications: select optional RS-232, RS-485, or license-free, spread spectrum radios; Event logging captures events as they happen and includes time and date stamping; Free software utility uses a Windows-based PC; Event logs can also be downloaded from the G3 for
archiving; Onboard USB connector is provided for programming via a laptop/PC.
