Schneider TM3DQ16T 16-Channel Output Module

Modicon TM3DQ16T 16-Channel Transistor Output Module

Product Introduction

The TM3DQ16T from Schneider Electric expands your control system with sixteen reliable transistor outputs. This module belongs to the Modicon TM3 family and works seamlessly with M221, M241, M251, and M262 controllers. Each output channel provides 500 mA at 24 V DC with positive logic sourcing configuration. Additionally, the TM3DQ16T delivers a fast response time of just 450 µs for both turn-on and turn-off operations. Consequently, this module excels in applications requiring precise and rapid actuator control. Its compact design and screw terminal connections simplify installation while maintaining high performance standards.

Technical Specifications of the TM3DQ16T

Output Characteristics: The TM3DQ16T features 16 discrete transistor outputs configured as source (PNP) type. Each channel operates at 24 V DC with a current rating of 500 mA. The maximum voltage drop measures less than 0.4 V, ensuring efficient power delivery to connected loads. Furthermore, the module supports a tungsten load up to 3 W per channel, making it suitable for incandescent indicator applications.

Performance and Speed: Response time is critical in many automation scenarios. This module achieves 450 µs for both state transitions, providing consistent and predictable switching performance. Meanwhile, the leakage current remains exceptionally low at 0.1 mA when outputs are switched off, preventing unintended activation of sensitive loads.

Power Consumption: The TM3DQ16T draws minimal power from the system. At 5 V DC via the bus connector, it consumes 5 mA when outputs are off and 15 mA when on. At 24 V DC, consumption is 0 mA off and 20 mA on. This efficiency reduces overall system power requirements and heat generation within the control cabinet.

Mechanical and Environmental Data

Physical Dimensions: This module features a compact form factor with height of 90 mm, depth of 84.6 mm, and width of only 27.4 mm. The net weight is 0.11 kg, while packaged weight reaches 0.22 kg. Its slim profile allows for efficient use of panel space in dense installations.

Mounting Options: The TM3DQ16T supports multiple mounting methods. It installs on top hat type TH35-15 or TH35-7.5 rails conforming to IEC 60715. Additionally, panel mounting is possible using a fixing kit, providing flexibility for various cabinet designs.

Environmental Resilience: Temperature tolerance ranges from -10 to 55°C for horizontal installation and -10 to 35°C for vertical mounting. Storage temperature spans -25 to 70°C. The module operates in relative humidity between 10 and 95% without condensation, with pollution degree 2 rating. IP20 protection is achieved with the protective cover in place.

Certifications: The TM3DQ16T holds multiple approvals including cULus, CE, UKCA, RCM, EAC, and cULus HazLoc. These certifications confirm compliance with international safety and performance standards.

Installation Guidelines for the TM3DQ16T

Proper installation ensures the TM3DQ16T delivers reliable performance throughout its service life. Begin by disconnecting all power sources before handling the module. Mount the unit securely on the chosen DIN rail or panel using appropriate hardware.

Wiring Instructions: The module features a 10 x 1.5 mm² removable screw terminal block with 3.81 mm pitch adjustment. Use 1.5 mm² copper conductors for reliable connections. For unshielded cable installations, maintain distances under 30 meters to ensure signal integrity. The terminal block's removable design facilitates convenient wiring and maintenance procedures.

Important Considerations:

• Ensure proper polarity for sourcing outputs

• Observe maximum cable length limitations for unshielded runs

• Maintain adequate clearance around the module for heat dissipation

• Use appropriate torque specifications for terminal connections

• Verify compatibility with your specific Modicon controller model
