| Introduction |
SUNIX ioSCADA SM series is a series of industrial Modbus I/O. It supports standard
Modbus (RTU & ASCII) protocol. Type of SUNIX ioSCADA modules include Digital
Input, Digital Output, Analog Input, Analog Output and Counter/Frequency Input
meet with most industrial automation applications. SUNIX ioSCADA series are
different to traditional I/O modules used in laboratory, SUNIX ioSCADA offers
great performance in Electric Power Plant, Steel Manufacturer and Petrochemical
Plant, which are harsh environment and require high immunity against noise,
more efficient, real-time response, long MTBF (Mean Time Between Failure), high
reliability and excellent measure precision. SUNIX ioSCADA are ideal for DCS, PLC
and SCADA system applications.SUNIX ioSCADA within convenience DIP Switch
for setting RS-485 ID address and Serial parameters , no need to configure by any
utility software. The modules are also embedded with RS-485 terminator. The RS485 network support 4,000 feet without network repeater.
The compact design enables DIN Rail installation. The slide-in cover design that helps user to keep track of the I/O structure. SUNIX
ioSCADA SM series not only for Data Acquisition but also include special control function such as I-to-O, ON/OFF Latch, Max./Min.
Lock, ON/OFF Delay Timer, TCP Control and Ramp Control in order to coordinate with SCADA system.
The ioSCADA modules work as independent controller while offering the data collection and control functions. Hence making
them perfect choice for SCADA & DCS applications at the industrial grade environments. |
