Introduction
When your automation system demands precise and reliable control of multiple actuators, the Schneider TM3DQ16T discrete output module delivers. This Modicon TM3 module provides 16 transistor outputs with positive logic (source), ensuring fast switching and minimal downtime. Designed for integration with Modicon M221, M241, M251, and M262 controllers, it is a practical solution for managing solenoids, indicators, and small motors.
Technical Specifications Breakdown
The TM3DQ16T offers a discrete output voltage of 24 V DC for transistor output, with a current rating of 500 mA per output. Its response time is 450 µs for both turn-on and turn-off, enabling rapid actuation in time-critical processes. The maximum leakage current is only 0.1 mA, and the voltage drop stays below 0.4 V, ensuring efficient power delivery. Power consumption is minimal: 5 mA at 5 V DC via bus connector when off, and 15 mA at 5 V DC when on. The module supports a maximum tungsten load of less than 3 W for transistor output, making it suitable for resistive loads.
Industry Applications
In manufacturing lines, the TM3DQ16T controls conveyor belt actuators and warning lights. Its fast response time (450 µs) reduces cycle delays, improving throughput. In packaging machinery, the module drives pneumatic valves and solenoids, where its 500 mA per output handles typical loads without external relays. The positive logic simplifies wiring with sourcing sensors, reducing installation errors.
Installation & Setup Guidance
Mount the TM3DQ16T on a top hat type TH35-15 or TH35-7.5 rail conforming to IEC 60715, or on a panel with a fixing kit. Use the removable screw terminal block (10 x 1.5 mm², pitch 3.81 mm) for output connections. Keep unshielded cable runs under 30 m to maintain signal integrity. The module's IP20 protection with a protective cover requires installation inside an enclosure. Ensure ambient air temperature stays between -10 and 55 °C for horizontal installation, or -10 to 35 °C for vertical mounting.
Maintenance & Reliability
Regular inspection of the terminal connections and LED indicators (one green LED per channel) helps detect early faults. The module withstands vibration up to 3.5 mm at 5–8.4 Hz and shock of 15 gn for 11 ms, ensuring durability in harsh environments. With pollution degree 2 and a wide storage temperature range (-25 to 70 °C), it suits most industrial settings. Periodic cleaning of the enclosure and checking for loose wires extends service life.
Compatibility & Integration
The TM3DQ16T is compatible with Modicon M221, M241, M251, and M262 controllers. It communicates via the bus connector, drawing 5 mA at 5 V DC (off state) and 20 mA at 24 V DC (on state). The module carries CE, cULus, UKCA, RCM, and EAC certifications, ensuring global compliance. For seamless integration, verify the controller firmware supports this module.
Selection Guide & Purchasing Advice
Before purchasing, confirm your controller model (M221/M241/M251/M262) and the required output count (16 points). The TM3DQ16T uses positive logic (source) — ensure your load wiring matches.

Frequently Asked Questions
Q: Can the TM3DQ16T drive inductive loads like relays?
A: Yes, each output provides 500 mA at 24 V DC. For inductive loads, use a flyback diode across the load to protect the transistor.
Q: What is the maximum cable distance for the outputs?
A: For unshielded cable, keep the distance under 30 m to avoid signal degradation.
Q: Does the module support sink (negative logic) wiring?
A: No, the TM3DQ16T uses positive logic (source) only. Outputs switch the positive side of the load.
Q: What certifications does the TM3DQ16T hold?
A: It is certified with CE, cULus, UKCA, RCM, EAC, and cULus HazLoc, meeting international standards.
Q: How do I know if the output is active?
A: Each channel has a green LED that illuminates when the output is on, providing clear local signaling.
