Digital input/output module, 4 inputs, 4 relay outputs, 24 VDC, spring terminals TM3DM8RG

Digital Input/Output Module – a versatile solution for automation

This digital input/output module, equipped with 4 inputs and 4 relay outputs, is a key element of automation systems. Designed to operate at 24 VDC, it offers flexibility and reliability in controlling various devices and processes. Thanks to the use of spring terminals, installation is quick and intuitive, which translates into time savings for both the installer and the end user.

Functionality and application

The TM3DM8RG module is compatible with Modicon M221, M241 and M251 ranges, making it a universal solution in many industrial applications. It can be used to control lighting, motors, valves and other devices requiring digital signals. A wide range of output voltages (30-264 V AC/DC) allows adaptation to different loads. The use of relays as digital outputs provides galvanic isolation and high resistance to interference.

Technical characteristics and benefits

The module is characterized by compact dimensions (27.4 x 90 x 84.6 mm) and low power consumption (2.5 W), which facilitates its integration in limited space. Spring terminals ensure a secure connection of wires without the need for tools, minimizing the risk of errors during installation. Thanks to the ability to operate at temperatures from -10 to 55°C (horizontal installation) and resistance to electromagnetic interference, the module performs well in demanding industrial conditions. Additionally, it has C-Tick and cULus certificates confirming its compliance with international safety standards. Output current at 2A allows control of most standard industrial loads. A signal change delay of 4-10ms ensures stable operation of the control system.
