- Model: TM2DMM24DRF
Schneider Electric TM2DMM24DRF is supplied as a new discrete I/O expansion module for professional replacement in compatible Modicon M238 and Twido systems.
Schneider Electric TM2DMM24DRF Discrete I/O Expansion Module – 16 24VDC Inputs and 8 Relay Outputs
A brand-new 24-channel discrete I/O module for professional expansion, maintenance or restoration of installed Modicon M238 and Twido systems – the right choice when the exact TM2DMM24DRF reference is required.
The module combines 16 digital 24VDC inputs and 8 relay outputs in one compact unit. Inputs support sink/source logic, while the relay outputs use normally open contacts for switching compatible loads.
With up to 2A per relay output, a 7A maximum output common, spring terminal block connection and 35mm DIN-rail mounting, it supports organised and efficient control-cabinet expansion.
Before ordering: verify the TM2DMM24DRF reference, PLC platform, input/output count, logic type, wiring diagram and relay loads.
Expand an installed PLC system with 24 discrete I/O points
The TM2DMM24DRF adds input signals and relay outputs without requiring an extensive redesign of an installed automation configuration.
- 16 × 24VDC inputs support connection to compatible sensors, switches and other discrete field signals.
- Sink/source input logic provides flexibility for correctly implemented control-cabinet wiring.
- Eight NO relay outputs support switching of compatible electrical loads within the stated limitations.
- 2A per channel and 7A per output common provide clear electrical parameters for planning connected loads.
- Compact DIN-rail construction saves valuable space and supports organised automation-cabinet expansion.
For systems that need more digital inputs and relay outputs
The discrete I/O module increases the available connections between a PLC, sensors, switches, signalling devices and compatible actuators. This enables the automation system to process more input information and control more output functions.
It is a practical choice for professional servicing or restoration of installed Modicon M238 or Twido systems where the established I/O architecture must remain intact.
- For digital sensors and switches: 16 × 24VDC inputs for compatible field signals.
- For relay-based control: eight normally open relay contacts for connected output functions.
- For professional system restoration: exact replacement of an installed TM2DMM24DRF module.
Important: before commissioning, confirm the allocation of inputs and outputs, common terminals and the load on every relay channel.
Compatibility where the exact module model is essential
The TM2DMM24DRF is a dedicated discrete I/O module for compatible Schneider Electric Modicon M238 and Twido controllers. With industrial expansions, the PLC platform, I/O configuration, electrical requirements and wiring diagram must match.
- Primary use: discrete I/O expansion in Modicon M238 and Twido systems.
- Input configuration: 16 × 24VDC digital inputs with sink/source logic.
- Output configuration: eight NO relay outputs with two output common points.
- Connection: one spring terminal block for organised wiring.
Essential check: this is not a universal I/O card for every PLC – confirm TM2 support, wiring and configuration of the installed system before ordering.
Relay outputs with clearly defined load control
Each relay channel uses a normally open contact and is rated for up to 2A per channel. The outputs are grouped, so the 7A maximum output-common limit must also be observed.
The module has local status indication and stated response times of up to 4ms for inputs and up to 10ms for output switching. This supports practical status monitoring of discrete signals in a compatible automation application.
Compact DIN-rail installation and correct connection
The module measures 42.9 × 90 × 70 mm, weighs approximately 0.14kg and is designed for 35mm symmetrical DIN-rail mounting. Its spring terminal block supports organised conductor routing inside the panel.
- Check the input voltage: digital inputs must use 24VDC within the 20.4–28.8V range.
- Check relay loads: do not exceed 2A per channel or 7A per output common.
- Follow the wiring diagram: connect input and output conductors according to the official documentation and PLC program.
Use suitable protection for loads and the supply as specified by the official wiring diagram for the individual application.
For professional and safe operation
- Disconnect power before connection and protect the control cabinet from unintended re-energisation.
- Observe relay limitations and select suitable protection for the connected electrical loads.
- Verify the PLC program before start-up, including input/output wiring and the operation of the complete application.
Incorrect connection or relay overload can cause incorrect system operation. Verify wiring, protection and every connected device before commissioning.
