Schneider Electric TM7NCOM08B CANopen interface module IP67 8E/A M8 content_copy

The TM7NCOM08B from Schneider Electric is a CANopen I/O interface module from the Modicon TM7 product series, designed for decentralized connection of sensors and actuators in industrial automation systems. It enables flexible and scalable expansion of controllers such as the Modicon M258 and LMC058 (PLC and PAC) via the CANopen bus. The device is designed for use in demanding environments and offers high mechanical and electrical robustness, with protection rating IP67 ensuring dust- and water-tight construction suitable for outdoor use.

Applications
This interface module is intended for industrial applications in automation technology, particularly in machine and plant engineering, where a decentralized I/O structure with minimal wiring effort is required. The modular design allows for easy integration into existing systems and the creation of individual configurations. The operating temperature range of -10 °C to 60 °C and storage temperature range of -25 °C to 85 °C make the device suitable for a wide range of operating conditions. The maximum operating altitude is 2,000 m above sea level, enabling use in high-altitude production facilities.

Functions and Equipment in Detail
The TM7NCOM08B features 8 inputs/outputs, connected via M8 connectors (3-pole), suitable for powering sensors or actuators. Power supply is provided via an M8 plug (4-pole) for input and an M8 socket (4-pole) for output. Electrical connection to the CANopen bus is made via an M12 plug (coding A, 5-pole) for bus input and an M12 socket (coding B, 4-pole) for bus output. Local signaling is provided by 2 LEDs for bus diagnostics, one LED for actuator power supply diagnostics, and one LED for sensor power supply diagnostics, enabling quick fault localization.

Technology Explained Simply
The interface module operates using the CANopen protocol, an open fieldbus standard widely used in industrial automation. Communication takes place over the CANopen bus, with I/O functions controlled by the controller (e.g. Modicon M258). The input voltage limit of 24 V DC is standard for most industrial applications. Mechanical mounting is done via 2 screws, with the operating position being freely selectable. The housing made of plastic ensures high mechanical stability and resistance to environmental influences.

Compatibility and Accessories
The TM7NCOM08B is compatible with controllers Modicon LMC058 and Modicon M258. Various accessory cables are available for connecting and expanding the system, including CANopen bus connection cables (e.g. TCSCCN1FNX1SA), power distribution cables (e.g. TCSXCNDFNX1V), and bus extension cables (e.g. TCSXCN1M1F1E). Additionally, a DIN-RAIL mounting plate (TM7ACMP) is available, enabling easy installation in enclosures. Certifications ATEX II 3g EEx nA II T5, CURus, GOST-R, and C-Tick confirm suitability for use in explosive atmospheres and various international markets.

Mounting and Installation
Mounting is done via 2 screws, with the device position being freely selectable. Wiring is carried out using the designated M8 and M12 connectors. The IP67 protection rating requires no additional protective measures during installation, as the device is already protected against dust and water. Ambient temperature and humidity (5–95 % without condensation), as well as vibrations (up to 7.5 mm amplitude at 2–8 Hz) and shocks (30 gn for 11 ms), comply with IEC 60721-3-5 Class 5M3, ensuring high reliability under industrial conditions.

Advantages in Operation
Using the TM7NCOM08B reduces wiring effort and simplifies maintenance thanks to its modular design and clear LED signaling. Direct connection to Modicon M258 and LMC058 controllers enables quick integration into existing systems. Certifications and high mechanical strength ensure safe and reliable operation in demanding industrial environments. The standard IEC 61131-2 is fulfilled, confirming compliance with international standards for automation systems.
