DSDI 115 57160001-NV Advantages
ABB DSDI 115 57160001-NV Digital Input Module provides reliable on-site digital signal acquisition solution for ABB Advant OCS distributed control system. Multi-channel integrated acquisition design can collect dozens of groups of field switch status signals at the same time, greatly improving the signal collection density of the control cabinet and optimizing the internal layout space of the cabinet. Every digital input channel is equipped with independent electrical isolation loop, which completely isolates the interference source formed by the potential difference between field equipment and control room, effectively avoiding signal misjudgment, channel burnout and other common faults of digital modules in industrial sites. The built-in hardware filtering circuit can automatically absorb the clutter pulse signal generated by mechanical switch instantaneous jitter, no need to set complex filtering parameters in the program, simplifying the later programming and debugging work of engineers. Hot-swap compatible design brings great convenience to daily equipment maintenance work; staff can directly pull out and replace faulty digital input modules without stopping the whole production control system, avoiding huge economic losses caused by full-line shutdown and greatly shortening the fault repair cycle. The built-in intelligent self-diagnosis system continuously monitors the working state of each input channel, once abnormal conditions such as channel open circuit, wiring short circuit and signal overload occur, the module will immediately send fault alarm information to the upper monitoring platform, maintenance personnel can quickly locate the abnormal channel without additional detection instruments. The integrated metal shielding shell can weaken the electromagnetic radiation interference generated by on-site high-power motors and frequency converters, ensuring long-term accurate collection of discrete digital signals. All DSDI 115 57160001-NV digital input modules are produced in strict accordance with ABB unified Swiss precision manufacturing standards, each unit passes high-low temperature cycle aging test, long-time continuous signal acquisition stability test, mechanical vibration resistance test and electromagnetic interference anti-disturbance verification before leaving the factory, with consistent electrical performance and strong interchangeability, which can be freely replaced during system expansion and production line renovation without modifying the original DCS control logic programs. The ultra-wide operating temperature range adapts to high-temperature, humid and dusty harsh cabinet environments in chemical, energy and papermaking industries, and there is no performance attenuation under 24-hour uninterrupted full-load operation.
DSDI 115 57160001-NV Applications
ABB DSDI 115 57160001-NV Digital Input Module is the core field signal acquisition matching component of ABB Advant OCS distributed control platform, widely applied to new DCS system construction and old control system transformation projects of thermal power plants, petrochemical production bases, pulp and paper continuous production lines, metallurgical smelting workshops, municipal sewage treatment stations and chemical fertilizer manufacturing factories equipped with Advant OCS systems. It is specially used to collect on-site equipment interlock contact signals, valve opening and closing feedback signals, motor running and fault discrete signals, safety switch state signals and transmit all collected digital signals to the DCS main controller for logical judgment and process interlock control. The product is applicable to complete set assembly of new project DCS cabinets, renovation and upgrading of Advant OCS control systems of old production lines, intelligent factory process control reconstruction and redundant backup control system construction projects, acting as the indispensable signal collection bridge connecting field mechanical and electrical equipment and Advant OCS distributed control system.
