Control and Detect: I/O Modules for Hazardous Areas
New for connecting sensors/actuators in zones 1/21 and 0/20: Intrinsically safe 4-channel I/O modules control various types of valves and economically record 0–20 mA, 4–20 mA and 3.6–21 mA standard signals per NAMUR NE43.
WAGO's New 4-Channel Analog Input Module (750-486) Offers New Possibilities
The four current input channels of the 750-486 4-AI Module allow standard signals to be recorded for the following measurement ranges: 0–20 mA and 4–20 mA (standard) and 3.6–21 mA (NAMUR NE43). The flexibility provided by the individually configurable channels and the narrow width open up new application areas.
Your Benefits with WAGO's 4 AI 0/4 … 20 mA Ex i Module:
- Configurable measuring ranges: 0–20 mA, 4–20 mA and 3.6–21 mA (NAMUR NE43)
- Compact design: space-saving and cost-effective analog module with 4 channels on an overall width of just 24 mm
- Channel-by-channel diagnostics (e.g., short circuit, wire break or out-of-measurement range)
- ATEX, IECEx certified
