WAGO 750-555 4-20mA Output Module with Galvanic Isolation

Product Overview

The WAGO 750-555 is a 4-channel analog output module from the WAGO-I/O-SYSTEM 750 series, designed to generate standardized 4-20 mA current signals for controlling field actuators. As a fundamental component within WAGO’s modular I/O architecture, the WAGO 750-555 enables direct wiring of four 2-wire actuators through its CAGE CLAMP connections, with all output channels sharing a common ground potential . This module serves as the interface between the control system’s digital processing world and the analog actuation devices found throughout industrial processes.

The WAGO 750-555 transmits output signals with 12-bit resolution and provides electrical isolation of 500V between the system and field levels, ensuring signal integrity even in electrically noisy industrial environments . Power for the module’s outputs is derived from the field-side 24VDC supply via power jumper contacts, while the system-side logic operates from the 5VDC backplane bus . The WAGO 750-555 occupies a compact 12mm width on DIN-35 rail and is fully compatible with all fieldbus couplers and controllers within the 750/753 series ecosystem.

As a standard analog output slice module, the WAGO 750-555 incorporates diagnostic capabilities including green status LEDs for operational indication and red error LEDs that activate upon wire breaks or unacceptable load impedance combinations . The module’s robust design, combined with comprehensive approvals including UL, ATEX, IECEx, and marine certifications, positions the WAGO 750-555 as a reliable solution for demanding industrial automation applications spanning manufacturing, process control, and hazardous area installations .
