Schneider Electric's Modicon TM3D TM3 series I/O module

Schneider TM3D is an expansion I/O module in Schneider Electric's Modicon TM3 series, used in programmable logic controller (PLC) systems. The following is a brief introduction:

Product Features

High compatibility: It is an expansion I/O module for Modicon M221, M241, M251 and M262 logic controllers, and can work well with these controllers to improve control system performance.

Multiple functional modules: There are multiple types such as discrete input modules and discrete output modules. For example, TM3DI8 is an 8-channel discrete input module, and TM3DQ8U is an 8-channel discrete output module, which can meet different input and output control requirements.

Good electrical performance: For example, the TM3DI16 discrete input module has an input voltage of 24V DC, an input current of 7mA, an input impedance of 3.4kΩ, and a response time of 4ms (on) and 4ms (off); the TM3DQ8U discrete output module has an output voltage of 24V DC, and a current consumption of 20mA at 24V DC through the bus connector. It can control variable speed drives or other devices with current and voltage inputs, and has 2300V AC insulation between outputs and internal logic, 750V AC insulation between outputs, and 1500V AC insulation between output groups.

Easy installation: It supports IEC 60715 standard TH35-15, TH35-7.5 top hat rail installation, and can also be installed on a board or panel through a fixing kit. The module adopts a simple interlocking assembly mechanism for easy assembly and maintenance.

Suitable protection level: IP20 protection level, can prevent objects larger than 12.5mm from intruding, suitable for general industrial environments.

Complete product certification: passed CE, C-tick and other certifications, in line with EN/IEC 61131-2, EN/IEC 61010-2-201 and other standards, quality and safety are guaranteed.
