TM3DQ8R | Schneider Modicon TM3 8 Relay Output Module

Introduction to the TM3DQ8R

When your automation system demands robust and cost-effective discrete output control, the TM3DQ8R from Schneider Electric delivers. This Modicon TM3 relay output module provides 8 normally open relay outputs, each rated for 24 V DC or 240 V AC at 2000 mA. By integrating this module, you reduce wiring complexity and improve system reliability, translating to lower installation and maintenance costs over time.

Key Features & Technical Specs

• 8 discrete relay outputs with normally open contacts.
• Supports positive or negative logic for flexible control.
• Rated output current: 2000 mA per relay.
• Response time: 10 ms turn-on, 5 ms turn-off.
• Mechanical durability: 20,000,000 cycles for long service life.
• Low power consumption: 5 mA at 5 V DC (state off) and 40 mA at 24 V DC (state on).
• Insulation: 2300 V AC between output and internal logic.
• CE, cULus, UKCA, RCM, EAC, and cULus HazLoc certified.

Unique Insight: The 2000 mA per relay output enables direct switching of medium-current loads, reducing the need for external contactors in many applications. This cuts component costs and simplifies panel design.

Cost-Benefit & ROI

Choosing the TM3DQ8R lowers total cost of ownership through its 20 million cycle mechanical durability, minimizing replacement frequency. Its low power consumption (40 mA at 24 V DC when on) reduces energy bills over the module's life. The 8 outputs per module also optimize I/O density, saving rack space and lowering per-point costs.

Applications & Use Cases

In packaging lines, the TM3DQ8R controls solenoid valves and actuators reliably. For material handling systems, its fast 5 ms turn-off time improves cycle efficiency. Additionally, building automation projects benefit from its ability to switch lighting or HVAC relays directly, reducing intermediate hardware.

Installation & Setup

Mount the TM3DQ8R on a TH35-15 or TH35-7.5 DIN rail per IEC 60715, or on a panel with a fixing kit. Use the removable screw terminal block (11 x 2.5 mm², 5.08 mm pitch) for secure wiring. Keep unshielded cable runs under 30 meters for relay outputs to maintain signal integrity. The module draws power from the bus connector, so no separate supply is needed.

Maintenance & Reliability

With IP20 protection and a pollution degree 2 rating, the TM3DQ8R suits clean industrial environments. Operate between -10°C and 55°C (horizontal) or 35°C (vertical). The 20 million cycle mechanical durability means fewer replacements, directly lowering maintenance costs. Regular visual inspection of LED indicators per channel helps catch faults early.

Compatibility & Integration

The TM3DQ8R integrates seamlessly with Modicon M221, M241, M251, and M262 controllers via the bus connector. It complies with EN/IEC 61131-2 standards, ensuring interoperability in mixed-vendor systems. No additional communication protocols are required for basic operation.
