Hello Забери билет от Гос.Лото,
In this issue we cover a variety of topics including exploring the Ins and Outs of I/O, how to use dual input temperature technologies to ensure uninterrupted process monitoring, and how to maintain proper HVAC airflow rates that enable humidification and temperature controlling equipment to perform as designed.
Defining the difference between Local and Remote I/O is quite straightforward, but the defining differences between Remote I/O and Distributed I/O can be more nuanced and can be further confounded by vendors' definitions or marketing collateral. In an article originally published in Control Engineering Europe, Moore Industries Europe General Manager Paul Harris talks us through the different types of I/O offerings that are available today, to highlight the importance of making the right choice for an application.
Dual Sensor Input Allows For Uninterrupted Process Monitoring
Temperature sensor failure can wreak havoc on processes where maintaining temperature is critical and monitoring must be continuous. Whether it's a runaway temperature that spoils a batch or a process interruption when an alarm shuts down the process due to a sensor failure, you can lose time and money.
The ambient air or environment plays a critical role in many manufacturing industries that require maintaining sterile or aseptic environments served by HVAC systems. Controlling different parameters, such as the air's temperature and humidity is certainly vital for ideal manufacturing conditions. But if continuous flow rates are not also tightly monitored and controlled, humidification and temperature controlling equipment cannot perform as originally designed.
Remote I/O and RTUs
Moore Industries Remote I/O and RTU products eliminate expensive T/C and RTD extension wire and other point-to-point wires by sending temperature measurements, process monitoring and control signals between the field and control room on one digital communication link.
