Schneider TM3DQ16R Relay Output Module for Modicon TM3 PLCs
Product Introduction
The TM3DQ16R belongs to the Schneider Electric Modicon TM3 series. It is a digital output module with sixteen relay channels. Each channel uses a normally open contact. Moreover, the relay design handles both DC and AC loads. This module switches valves, contactors, lamps, and other field devices. Therefore, it fits many industrial control duties.
Engineers pair this unit with Modicon M221, M241, M251, and M262 platforms. In addition, the removable screw terminal block simplifies field wiring. The 3.81 mm pitch keeps connections compact. With a width of only 27.4 mm, it saves valuable DIN rail space while offering a high channel count.
Technical Specifications
The TM3DQ16R provides sixteen digital output channels. Its contacts support 5 to 30 Vdc and 5 to 250 Vac. Each channel carries up to 2 A. Meanwhile, each common line handles up to 7 A. This rating allows several loads to share one common terminal.
The output uses a mechanical relay. Consequently, response time depends on the relay switching speed. Isolation between output and internal logic is rated at 500 V AC. Furthermore, isolation between channel groups reaches 1500 V AC. Therefore, the module separates different load circuits well.
Diagnostics cover module status and bus status. These LEDs help during commissioning. Moreover, the module draws 37 mA at 5 V DC from the TM3 bus when all outputs are on. With all outputs off, the bus current falls to 5 mA. Power comes through the TM3 bus, so no separate supply is required.
Mechanical and Environmental Parameters
The TM3DQ16R measures 90 mm high, 27.4 mm wide, and 84.6 mm deep. It weighs only 0.11 kg. Thus, it adds little weight to the cabinet. The protection rating is IP20. So, install it inside a clean enclosure.
Operating temperature ranges from 0 to +55 °C. Storage temperature ranges from -25 to +70 °C. These ratings fit typical factory floors. The removable screw terminal block has a 3.81 mm pitch. This design allows fast replacement without rewiring the whole strip.
Installation Guide
First, mount the module on a DIN rail next to the controller. Next, connect the TM3 bus connector. Then, wire the loads to the screw terminals. Tighten each screw to the recommended torque. After that, check the output assignment in the programming software.
Additionally, verify the load voltage before power-up. The TM3DQ16R accepts both DC and AC circuits. Therefore, keep AC and DC wiring separated where possible. Meanwhile, respect the 7 A limit per common line. This practice prevents relay damage. Finally, confirm the status LEDs after applying power.
