The Schneider DTA 101 Modicon 984 rack houses I/O modules for industrial control systems. This unit weighs 2.8 kg and measures 35.0 cm x 25.0 cm x 12.0 cm. It provides 10 I/O module slots on a single chassis. The rack contains one passive backplane and one grounding bar. For energy storage, it includes no capacitor due to its passive design. Consequently, the Schneider DTA 101 requires no power supply for the backplane itself.

Rack Design and Capacity
The Schneider DTA 101 features 10 I/O module slots for flexible system configuration. You can install any Modicon 984 compatible module into these slots. Therefore, this rack supports digital, analog, and specialty modules simultaneously. The passive backplane provides all necessary signal routing between modules. Consequently, no active components can fail on this backplane.
Physical Construction
This rack uses painted steel construction for durability in industrial environments. The grounding bar ensures proper electrical safety for all installed modules. Thus, you can connect field devices without worrying about ground loops. The slot pitch measures 2.5 cm between adjacent slots. Hence, modules have adequate space for heat dissipation and wiring access.
Power and Backplane Features
The Schneider DTA 101 contains no active components or energy storage devices. Therefore, it requires an external power supply to power the installed modules. The backplane simply passes signals and power between the power supply and modules. Consequently, this passive design offers extremely high reliability over time. The rack itself cannot fail electronically because it has no electronics.
Installation and Mounting
You can mount the Schneider DTA 101 on a flat panel or in a standard rack. Use M6 screws through the four mounting holes on its frame. The rack requires 10 cm of clearance on each side for proper airflow. Additionally, leave 15 cm of space in front for module access. The Schneider DTA 101 works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This Modicon 984 rack operates reliably from 0°C to +60°C. It also withstands 95% relative humidity without condensation. The rack survives vibration up to 2g from 10 to 150 Hz. Therefore, the Schneider DTA 101 suits most industrial control rooms perfectly.
