Schneider Electric's Modicon TM3DM8R TM3 series I/O module

Schneider Electric's Modicon TM3DM8R is a digital I/O module in the Modicon TM3 series. Here is a detailed introduction:

Basic Information

Product Model: TM3DM8R.

Product Type: Digital I/O module, suitable for Modicon M221, M241, M251, and M262 logic controllers.

Quantity of I/O Channels: It has 8 I/O channels, including 4 digital inputs and 4 digital outputs.

Electrical Characteristics

Input Characteristics: The input voltage is 24V DC, the input current is 7mA, and the input impedance is 3.4kΩ. The input logic can be sink or source (positive/negative), with voltage state 0 guaranteed to be 0 - 5V and voltage state 1 guaranteed to be 15 - 28.8V.

Output Characteristics: The output type is relay normally open, which can support output voltages of 24V DC or 240V AC, and the output current is 2000mA. The maximum current per output common is 7A, and the minimum load is 10mA at 5V DC.

Mechanical Characteristics

Dimensions: 90mm×23.6mm×70mm.

Weight: 0.095kg.

Mounting Method: It supports top - hat type TH35 - 15 and TH35 - 7.5 rails that conform to IEC 60715, and can also be mounted on a plate or panel with a fixing kit.

Performance Characteristics

Response Time: 4ms (turn - on) and 4ms (turn - off).

Insulation Performance: There is insulation between the input and internal logic at 500V AC.

Environmental Characteristics

The specific environmental characteristic data such as operating temperature, storage temperature, humidity, pollution degree, and IP protection level are not clearly provided in the common data. But generally, similar modules are within the range of -10 - 55°C for operating temperature, and the IP protection level is IP20 with a protective cover in place.
