Schneider 140DAI35300C Discrete Input Module

The Schneider 140DAI35300C provides reliable discrete input acquisition for industrial control applications. This input module belongs to the Modicon Quantum series for high-performance automation architectures. Engineers will value its high channel density and robust isolation characteristics.

Technical Specifications & Physical Characteristics

This discrete input module features 32 input points organized into four isolated groups of eight channels each. The 140DAI35300C accepts 24 VDC signals from sensors, limit switches, and pushbuttons. Each group provides 500V isolation between field wiring and the backplane bus.

Specifically, the module measures approximately 140 mm in height, 30 mm in width, and 130 mm in depth. Its total weight reaches roughly 0.38 kg, allowing for stable mounting in Quantum racks. Furthermore, this module contains no internal energy storage components, which simplifies maintenance procedures.

Signal Acquisition and Field Integration

You can connect field devices directly to the 32 input points without external interface components. The four isolated groups allow you to separate signals from different power zones effectively. Each channel draws only 7 mA, minimizing load on field power supplies.

Moreover, the 140DAI35300C delivers a 1 ms response time for rapid detection of input state changes. This speed suits applications requiring fast reaction to machine events. For similar industrial control components, you can explore the RMS TSG TZ C Static Trip unit series.

Installation and Operational Features

The physical layout of the Schneider 140DAI35300C facilitates straightforward panel integration and wiring. Technicians will find the terminal blocks clearly labeled for error-free field connections. The module’s compact design enables high-density mounting within automation enclosures.

Furthermore, the unit incorporates no internal energy storage elements across its circuitry. This characteristic eliminates discharge waiting time during system power-down. Consequently, you can perform maintenance or replacement tasks immediately without safety delays.
