Schneider Electric TM3XTRA1 Remote Transmitter Module

TM3XTRA1 Modicon TM3 Remote Transmitter Module

Product Introduction

The Schneider Electric TM3XTRA1 remote transmitter module serves as a vital extension for the Modicon TM3 automation platform. This device allows you to place I/O points farther from the main controller, thus offering greater flexibility in machine layout and cabinet design. Specifically, it works seamlessly with Modicon M241, M251, M221, and M262 logic controllers. Consequently, you can standardize on a single remote I/O solution across multiple machine types.

Furthermore, this TM3XTRA1 module communicates with its paired receiver through a simple two-conductor RJ45 extension cable. This setup significantly reduces wiring time and minimizes the risk of connection errors. Additionally, its compact housing saves valuable space inside your control panel. The module’s design adheres to strict international standards, including IEC 61131-2 and UL 508, ensuring reliable operation in a wide range of industrial environments.

Key Technical Specifications

The TM3XTRA1 offers well-defined electrical characteristics for predictable system performance. It consumes 100 mA at 5 V DC when active and only 30 mA in the off state. Moreover, its maximum power dissipation is just 0.6 W, which helps keep thermal buildup inside the cabinet to a minimum. This low power consumption makes it an energy-efficient choice for large installations with many remote nodes.

For connectivity, the module provides an RJ45 connector for the bus receiver and a screw terminal for the functional ground connection. A pair of green LEDs on the front panel gives you clear local status indication: one shows power supply presence, while the other confirms link activity. Therefore, troubleshooting becomes faster and more straightforward without needing a programming terminal.

The permitted cable distance between the transmitter and receiver ranges from 0.5 to 5 meters. This range gives you practical flexibility for positioning remote I/O stations near sensors and actuators. In addition, the module complies with stringent EMC requirements. It withstands electrostatic discharges of 8 kV in air and 6 kV on contact per IEC 61000-4-2. Radiated immunity reaches 10 V/m from 80 MHz to 1 GHz, and conducted disturbance immunity is 10 V from 0.15 to 80 MHz per IEC 61000-4-6.

Environmental and Mechanical Durability

Industrial automation demands hardware that survives harsh conditions. The Schneider Electric TM3XTRA1 excels in this area with a wide operating temperature range of -10°C to 55°C for horizontal mounting and -10°C to 50°C for vertical orientation. Storage temperatures can go from -40°C up to 70°C, so spare units remain ready for use even in extreme warehouses.

Humidity tolerance is equally impressive, covering 5% to 95% relative humidity without condensation. The module also carries an IP20 protection rating, provided the protective cover remains in place. This rating guards against solid objects larger than 12.5 mm, making it suitable for clean, dry indoor panels. Additionally, the pollution degree is rated at 2, meaning only non-conductive pollution occurs temporarily.

Vibration and shock resistance are critical for machinery applications. On a DIN rail, this TM3XTRA1 handles 3.5 mm displacement from 5 to 8.4 Hz and 3 gn acceleration from 8.4 to 150 Hz. For panel mounting, the same levels apply, giving you mounting flexibility. Shock resistance is rated at 15 gn for 11 ms, ensuring the module stays functional even in high-impact environments like stamping presses or heavy conveyor systems.

Installation and Mounting Guidance

Mounting the TM3XTRA1 is straightforward, thanks to its support for standard TH35-15 and TH35-7.5 DIN rails per IEC 60715. Alternatively, you can fix it directly to a plate or panel using the optional mounting kit. This flexibility allows you to integrate the module into existing cabinets with minimal effort. For vertical mounting, ensure the ambient temperature stays within the specified 50°C limit to maintain optimal performance.

When planning your layout, remember to maintain proper clearance and spacing around the module for adequate airflow and easy access to the RJ45 connector. The module’s compact dimensions—90 mm height, 73.3 mm depth, and only 23.65 mm width—mean you can place multiple units side by side without crowding the panel. Consequently, this dense packing capability is ideal for high-channel-count systems.

For panel surface mounting, we recommend installing a mounting strip first. Then, follow the hole layout provided in the product datasheet for accurate positioning. Always connect the functional ground terminal to ensure proper EMC performance and safety. Finally, use a high-quality shielded extension cable between the transmitter and receiver to preserve signal integrity over the 5-meter maximum distance.

Packaging and Logistics

Each individual TM3XTRA1 comes in a single-unit package measuring 10.5 cm (L) x 12.5 cm (W) x 7.5 cm (H) and weighing 163 grams. Larger bulk packages are also available: an S03 carton holds 8 units with dimensions of 40 cm x 30 cm x 30 cm and weighs 1.783 kg. For high-volume orders, the P06 pallet contains 144 units, measuring 80 cm x 60 cm x 75 cm and weighing 37 kg. These diverse packaging options simplify inventory management and reduce per-unit shipping costs.

All shipments are dispatched via trusted global couriers, including FedEx, UPS, and DHL. This ensures your TM3XTRA1 modules arrive quickly and safely, no matter where your facility is located. The product originates from Indonesia (country of origin: ID), and each unit carries an 18-month warranty from Schneider Electric.

Frequently Asked Questions

1. Which controllers are compatible with the TM3XTRA1?
The TM3XTRA1 works with Modicon M241, M251, M221, and M262 programmable logic controllers. This broad compatibility makes it a versatile choice for various machine designs within the Modicon TM3 ecosystem.

2. What is the maximum cable length between the transmitter and receiver?
The permitted cable distance is up to 5 meters using a two-conductor RJ45 extension cable. For best performance, keep the cable length above 0.5 meters and use shielded cabling in noisy environments.

3. Can I mount this module vertically inside my control panel?
Yes, vertical mounting is permissible. However, derate the maximum operating temperature to 50°C for vertical installation. Horizontal mounting supports up to 55°C ambient air temperature.

4. Does the TM3XTRA1 require an external power supply?
No external supply is needed. The module draws its operating current directly from the bus connector at 5 V DC, consuming 100 mA in the on state and 30 mA when off.

5. What do the two green LEDs on the front panel indicate?
One LED signals that power is present, while the other shows the link status between the transmitter and receiver. These indicators provide quick visual feedback for system health and troubleshooting.
