Schneider Modicon TM3 TM3DQ16TG 24 Vdc Output Module

Schneider TM3DQ16TG Digital Output Module for Modicon TM3 PLCs

Product Introduction

The TM3DQ16TG belongs to the Schneider Electric Modicon TM3 series. It is a digital output module with sixteen transistor channels. Each channel delivers a 24 Vdc source signal. Moreover, the PNP output design matches common industrial wiring. This module switches loads such as relays, lamps, and small solenoids. Therefore, it handles many machine control duties.

Engineers pair this unit with Modicon M221, M241, M251, and M262 platforms. In addition, the removable spring-cage 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 doubling the channel count of smaller modules.

Technical Specifications

The TM3DQ16TG provides sixteen digital output channels. Its nominal voltage is 24 Vdc. Each channel supplies up to 0.5 A. Meanwhile, the transistor source configuration delivers PNP signals.

Response time reaches 450 µs maximum for both turn-on and turn-off. Consequently, the module suits fast switching tasks. Isolation between output and internal logic is rated at 500 V AC. However, no isolation exists between channels. Therefore, plan the load wiring with care.

Diagnostics cover module status and bus status. Besides, short-circuit and overload protection guard each output. These features reduce downtime during faults. Furthermore, the module draws 35 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 TM3DQ16TG 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 spring-cage 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 spring terminals. Use a small screwdriver to open each clamp. After that, insert the stripped wire and release the clamp.

Additionally, verify the PNP wiring before power-up. The TM3DQ16TG sources current to the load. Therefore, connect the load between the output and the negative supply. Meanwhile, keep output cables away from sensitive analog lines. This practice reduces electrical noise. Finally, confirm the status LEDs after applying power.
