Hello Забери билет от Гос.Лото,
Moore Industries would like to wish you a happy and prosperous 2023! In this month's newsletter, we focus on signal isolation solutions: VFD noise rejection with our ECT-DIN Signal Isolator, passing HART data while isolating analog signals with our HART isolators, Isolators in a Cabinet in Class I, Div 2 Location, and The FDY PC-Programmable Frequency-to-DC Transmitter with Display.
Due to their efficiency and energy savings, VFDs (Variable Frequency Drive) are replacing AC and DC motors in water and wastewater facilities. Unfortunately, VFDs can generate a lot of high-frequency noise that can wreak havoc on control and monitoring devices such as PLCs and distributed control systems.
Pass HART data while isolating analog signals
Signal isolators are highly economical solutions to common and costly problems that plague many of today's smart process loops such as ground loops and ambient electromagnetic noise problems. But they do much more than that: they can be used to share and split process signals and even enhance your plant-wide HART investment by also passing valuable HART data to and from your host systems.
Many process facilities need 4-20mA signals from field transmitters and analyzers to be shared with their BPCS (Basic Process Control System) and alternate monitoring systems or backup PLCs. But wiring these three elements in series breaks loop integrity and can cause problems when the secondary or backup system fails or is disconnected
PC-Programmable Frequency-to-DC Transmitter
The FDY PC-Programmable Frequency-to-DC Transmitter with Display monitors frequency, period, high or low pulse width, and contact closure signals. It converts the input signal to a proportional, input-to-output isolated 4-20mA output ready for direct interface with a readout instrument, recorder, PLC, DCS, SCADA system, or other readout instruments.
