WAGO 750-486

WAGO 750-486 – 4 AI 0/4-20 mA Single-Ended, Intrinsically Safe

Overview

The WAGO 750-486 is a 4-channel analog input module designed for intrinsically safe signal acquisition in hazardous areas (Zone 0/1). It supports 0-20 mA and 4-20 mA current signals, single-ended wiring with 3-wire sensors, and includes diagnostics per channel (wire break, short circuit, over/under range) based on the NAMUR NE43 standard.

Key Features

• Four analog input channels, 0-20 mA and 4-20 mA, single-ended

• Intrinsically safe (Ex i) design suitable for Zone 0/1 applications

• NAMUR NE43 diagnostic compliance

• LED indicators: green for module availability, red for error conditions per channel

• Shield connected to DIN-rail for signal integrity

• Resolution: 12 bits plus sign bit

• Compact module: 24 mm width
