ABB 70EA02A-ES Product Details
Product Type:Analog Input Module(AI Module).
Model Code:70EA02A-ES.
Core Functions:
Signal Acquisition:This module can receive analog signals from field transmitters(such as temperature,pressure,and flow transmitters).
2-Wire Transmitter Support:The”ES”in the model number may indicate that it is designed specifically for 2-wire transmitters and can simultaneously power the transmitter and receive signals.
Multi-Channel Input:Modules typically have multiple channels.For example,”(x4)”mentioned in the literature may indicate that it has four input channels.
Galvanic Isolation:As an industrial control module,it typically features electrical isolation to protect the control system from external electrical noise and ground loop interference.
Applications:
Process Control:In industries such as power,petrochemical,and chemical industries,it is used as part of an ABB DCS system to monitor and control analog parameters in production processes.
Industrial Automation:Any industrial application that requires acquiring analog signals from 2-wire transmitters.
