WAGO 750-455

WAGO 750-455 – 4 AI 4-20 mA Single-Ended

Overview

The WAGO 750-455 is a 4-channel analog input module designed for measuring current signals in the range of 4-20 mA. It is single-ended, providing a common ground across all input channels. Each input is electrically isolated from the system side, supporting accurate signal transmission with 12-bit resolution. The module is compact, holds IP20 protection, and is intended for integration in the WAGO I/O System 750 series.

Key Features

• 4 analog input channels (4-20 mA)

• Single-ended signal characteristic with common ground

• 12-bit resolution per channel

• Fast conversion time: approx. 10 ms

• LED indicators for error detection (overrange, underrange, open wire)

• Input resistance ≤ 100 Ω at 20 mA

• Galvanic isolation between field and system sides (500 V)

• Slim 12 mm module width
