PLCs, Power Supplies & Others

The Schneider TM2DDI16DT digital input module captures signals from field sensors reliably. This unit weighs 0.18 kg and measures 9.0 cm x 7.2 cm x 6.0 cm. It provides 16 digital input channels for the Modicon M221 system. The module contains 16 opto-isolators and one filter circuit. For energy storage, it includes one 47µF electrolytic capacitor. Consequently, the Schneider TM2DDI16DT maintains input states during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the Schneider TM2DDI16DT. Use this data for your system integration planning.

Input Channel Features

Each of the 16 input channels uses a dedicated opto-isolator for signal isolation. The Schneider TM2DDI16DT accepts 24V DC signals from standard industrial sensors. Therefore, you can connect proximity switches, limit switches, and push buttons directly. The input current sits at 5 mA for reliable detection. Thus, the module presents a very light load to your field devices.

Filter and Response Performance

The response time reaches 1 millisecond for standard operation. You can select a 3 ms filter for noisy environments. Consequently, this flexibility helps you balance speed versus noise immunity. The on-state voltage range spans 15V to 30V DC. The off-state voltage stays below 5V DC for guaranteed detection. Hence, the Schneider TM2DDI16DT provides clean and reliable signal recognition.

Power and Energy Storage

The Schneider TM2DDI16DT draws only 40 mA from the 5V DC bus. Hence, its total power consumption equals just 0.2W. The onboard 47µF capacitor provides 5 milliseconds of hold-up time. This short backup protects input states during minor voltage sags. Furthermore, the module generates virtually no heat during operation.

Installation and Connectivity

You can mount the Schneider TM2DDI16DT on a standard DIN rail. The module snaps directly onto the rail without tools. The 18-pin removable terminal block accepts wire sizes from 0.2 mm² to 1.5 mm². For best performance, use shielded cables for long input runs. The Schneider TM2DDI16DT works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This digital input module operates reliably from -10°C to +55°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the Schneider TM2DDI16DT suits most compact automation systems perfectly.
