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 4-Channel Digital Output Module (750-539) Offers New Possibilities

WAGO's new intrinsically safe 4-channel 24 VDC VALVE Ex i Digital Output Module (750-539) controls various types of valves from different manufacturers (e.g., Bosch, SMC, Festo and Norgren). Benefit from the special I/O module with double channel count and higher output current.

Your Benefits with WAGO's 4 DO 24 VDC VALVE Ex i Module:

  • Output current of max. 50 mA
  • Control valves and valve terminals in Zones 1/21 and 0/20
  • Channel-by-channel diagnostics (e.g., short circuit and wire break)
  • Compact design: space-saving and cost-effective
  • ATEX, IECEx certified

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
