Model Number AD204WEB
Function Type 4-Channel Analog Input Signal Conditioner / Isolator
Input Signal 4-20 mA (accepts current signals from field transmitters)
Output Signal 4-20 mA (isolated current signal output to the control system)
Number of Channels 4 channels, with full isolation between channels and from the power supply.
Power Supply Typically requires an external power source, such as 24 VDC.
Accuracy High typical accuracy, e.g., ±0.05% of span.
Isolation Channel-to-channel isolation and channel-to-power isolation (typically 1500 VAC), preventing ground loops and signal noise.
Load Capacity The maximum load resistance the output can drive (e.g., 0-600 Ω).
Response Time Very fast, typically less than 100 ms.
Operating Temperature -40°C to +85°C, suitable for harsh industrial environments.
Mounting Standard 35mm DIN rail mounting.
Certifications Typically carries international certifications like CE, ATEX (for hazardous areas), IECEx, FM.
The Foxboro AD204WEB is a 4-channel analog input signal conditioner and isolator. It is a system component designed for use in industrial process control systems, typically mounted on a DIN rail within a control cabinet.
