SPDSI22 Harmony机架I/O系统利用各种输入、输出和信号调理模块

■ Wide variety of Input/Output (I/O) types: Analog (high and low levels, and temperature), digital, control, turbine control, field bus, and sequence of events (SOE).
■ Modular to meet varying I/O requirements: I/O modules are provided to meet nearly all I/O processing requirements (isolation, A/D conversion, auto calibration).
■ Dedicated, secure I/O communications: Fast response parallel bus supports up to 64 I/O modules to a single controller pair.
■ Graceful degradation of I/O: Configurable, fail-safe output modes.
■ Compatibility with existing systems: I/O modules can be used to expand existing INFI 90® OPEN, in conjunction with Harmony block I/O, and can communicate directly with all Harmony controllers.
■ Surface-mount technology: Provides high reliability and consistent quality

The Harmony rack I/O system utilizes a wide variety of input, output, and signal conditioning modules to interface process signals to the Symphony™ Enterprise Management and Control System. Module types, ranging from standard analog and digital I/O to specialty I/O such as turbine control, field bus, and SOE, can be combined to provide a comprehensive set of functionality to meet all market and industrial requirements. In addition, Harmony rack I/O, providing functions at the module mounting unit (MMU) level, and Harmony block I/O can operate in parallel with a single set of Harmony controllers to form an optimum solution for a specific application.
