Purchase now: Wago 750-600 End Module
Purchase now: Atlantech Drives provides you the Wago 750-600, the mandatory **End Module (Bus Termination)** for every WAGO-I/O-SYSTEM 750 assembly. It might look like a simple plastic cover, but it contains a termination resistor network that closes the internal data bus loop. Without the 750-600 installed at the very right-hand end of the node, the Fieldbus Coupler will report a «Bus Error» and none of the I/O modules will function.
Technical Specifications and Functionality
The 750-600 has no external I/O terminals. Its sole purpose is to mechanically secure the last module in the rail and electrically terminate the internal high-speed data bus to prevent signal reflections. It connects the data contacts and the power jumper contacts, ensuring the internal circuit is complete. It is passive and does not consume significant power or require addressing.

Expert Installation Advice: The «Missing Link»
The most common startup error. Expert Tip: If your Wago coupler LED is blinking a «I/O Error» code (often 2 flashes), check the 750-600 first. Technicians often forget to order it or lose it during assembly. A standard terminal block end plate is NOT a substitute. You must have the electronic 750-600 module clicked in place. Keep a few spares in your maintenance stock; a lost end module can stop an entire production line.
Frequently Asked Questions (FAQs)
Q: Does it carry the 24V power?
A: No, the 750-600 terminates the data bus. The 24V field power (power jumper contacts) usually ends at the last I/O module, or flows into the 750-600 where it is safely dead-ended.
Q: Is there a shield connection version?
A: Yes, typical bus end modules are plain, but there are variants or accessories for shield termination if required, though usually shielding is handled at the coupler or specific shield clamps.
