Feimu Technology, as a professional supplier, has been focusing on the supply of Allen Bradley automation modules for a long time, and has brought you the high-performance communication expansion module Allen Bradley 1768-M04SE. This module is an original Allen Bradley product and is specially designed for CompactLogix controllers, used to achieve stable and high-speed data interaction between the controller and external devices.
Whether it is the serial port communication of old equipment or the new generation of industrial Ethernet communication, this module can be perfectly compatible. It is an ideal bridge for system upgrades, device networking, and multi-device interconnection. We insist on having a sufficient stock in reserve to ensure that you can receive prompt delivery when expanding the system or conducting emergency repairs, without delaying the production schedule.
The 1768-M04SE supports the EtherNet/IP high-speed industrial protocol, ensuring low latency and high stability for data upload, download, and real-time interaction. The module can operate at high speed on Ethernet while managing multiple serial port communications. Each channel works independently without interfering with each other, meeting the strict requirements for real-time performance and reliability in industrial environments.
In scenarios involving parallel connection of multiple devices and large data transmission, this module still maintains smooth connections without packet loss, stalling, or disconnection, fully meeting the demanding usage environments of automated production lines, motion control, and data acquisition. We only provide brand new, original quality products, strictly controlling Quality, and they are ready to use on the machine and stable for a long time.
The greatest feature of Allen Bradley 1768-M04SE is its integrated design of Ethernet + dual serial ports. In many factories, both new and old equipment coexist. Older machines only have serial ports, while new equipment only supports network ports. Previously, multiple converters were needed to achieve interconnection. With 1768-M04SE, only one module is required to complete all the connections.
Serial ports support custom configuration for master station and slave station modes, flexibly adapting to different brands of instruments, sensors, touch screens, frequency converters, etc. It also supports CIP Motion-related functions, which are very practical for motion control projects and is one of the most practical solutions in current automation expansion.
The Allen Bradley 1768-M04SE is equipped with a metal casing for enhanced protection against impact and vibration, making it suitable for the complex environment of a factory workshop. Daily maintenance is straightforward; simply ensure that iron filings do not enter the cooling holes. When not in use for a long time, simply disconnect the power and store it in a dry environment.
When plugging or unplugging the network cable and serial port cable, hold the connector body instead of directly pulling the cable. This will effectively protect the internal solder joints and interfaces. Under normal usage conditions, this module can operate stably for a long time, providing long-lasting and reliable communication support for the equipment.

Supported devices:
Typical configuration:
Each port operates independently. Data from one port does not affect other ports.
The 1768-M04SE is configured in Studio 5000. Follow these steps to set up the module.
Configuration steps:
Common mistakes:
The 1768-M04SE has LED indicators on the front panel. These provide immediate status information.
| LED | Status | Meaning | Action |
|---|---|---|---|
| PWR | Green | Module powered and operating normally. | No action needed. |
| PWR | Off | No power to module. | Check CompactLogix power. Check backplane connection. |
| Port 1-4 Status | Green | Port configured and communicating. | No action needed. |
| Port 1-4 Status | Red | Port communication error. | Check cable. Check device settings. Check configuration. |
| Port 1-4 TX | Flashing | Data transmission active. | No action needed. Normal operation. |
| Port 1-4 RX | Flashing | Data reception active. | No action needed. Normal operation. |
Allen Bradley 1768-M04SE modules are commonly counterfeited. Use these checks to verify authenticity.
If the module shows incorrect communication or port errors, suspect a counterfeit. Contact Feimu Technology with photos for verification.
Feimu Technology does not ship untested modules. Each 1768-M04SE goes through the following verification process before leaving our warehouse.
Test reports are available upon request. Email sales@feimutech.com for a copy of your module's test report.
Which controllers are the modules applicable to?
They are applicable to the 1768 CompactLogix controller platform, but cannot be directly used in the 1769 series of CompactLogix.
What does "Cyclic Time" in SERCOS network configuration mean?
It is the refresh cycle of the SERCOS ring network, which determines the real-time performance. There are 1ms, 2ms or 4ms, the shorter the cycle, the higher the control accuracy.
Feimu Technology, as a professional supplier deeply engaged in the industrial control field, has a large-scale intelligent warehouse. Allen Bradley 1768-M04SE is available in stock and directly dispatched in full process. It can quickly respond to urgent orders from both domestic and international markets.
