Description

The Wago 750-341 is an Ethernet TCP/IP Fieldbus Coupler in the WAGO-I/O-SYSTEM 750 series. It connects a WAGO 750-series I/O node as a slave to an Ethernet fieldbus network and is compatible with any Ethernet TCP/IP master using Modbus/TCP or EtherNet/IP. Refer to manufacturer documentation to confirm compatibility with your specific application.

This coupler supports up to 64 I/O modules (expandable to 250 with the 750-628 Bus Extension Coupler) and auto-configures a local process image of up to 2 kbytes in and 2 kbytes out, handling digital, analog, and specialty module data. It connects via an RJ-45 port at 10/100 Mbit/s and is powered by 24V DC, drawing a maximum of 500 mA input current. Wiring is via WAGO CAGE CLAMP® terminals accepting conductors from 0.08 mm² to 2.5 mm² (AWG 28–14).

The coupler is configurable via PC and supports IP address assignment through BootP, DHCP, or EEPROM-stored settings. The maximum cable run between a hub and the 750-341 is 100 m, with overall network length governed by standard Ethernet specifications. This product has been noted as discontinued/obsolete by WAGO and authorized distributors.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
