Schneider ASBDEP254C | Input Module

The Schneider ASBDEP254C provides high-precision analog input capabilities for the 800-Series platform. This input module features 4 analog input channels for voltage or current signals. It accepts 0-10 V DC and 4-20 mA inputs for flexible sensor connectivity. Weighing only 0.38 kg, the Schneider ASBDEP254C mounts easily on a DIN rail or panel. Its dimensions measure 125 mm x 90 mm x 65 mm.

Input Specifications and Signal Ranges

The Schneider ASBDEP254C offers 12-bit resolution for accurate measurement of analog signals. Each channel handles 0-10 V, ±10 V, 0-20 mA, or 4-20 mA inputs independently. The module provides a conversion time of only 2.5 ms per channel for fast response. Moreover, the Schneider ASBDEP254C includes built-in scaling from raw values to engineering units. Consequently, you can read pressure, temperature, or flow data directly in real-world units.

Energy Storage and Internal Components

The Schneider ASBDEP254C contains no internal battery for complete maintenance-free operation. It stores configuration data in non-volatile memory instead of battery backup. This module draws 200 mA from the 5 V DC backplane power supply. Additionally, it consumes 80 mA from the external 24 V DC field power supply. The Schneider ASBDEP254C includes 4 analog-to-digital converters for simultaneous signal processing. Therefore, it provides excellent channel-to-channel isolation and noise rejection.

Installation and Application Details

The Schneider ASBDEP254C mounts directly onto a standard 35 mm DIN rail. This input module requires an external 24 V DC power supply for analog circuit operation. Use shielded twisted pair cables for all analog signal wiring to minimize noise. Connect the cable shield to the functional ground terminal at the module end. The Schneider ASBDEP254C suits process control, HVAC monitoring, and machine automation tasks. It handles temperature sensors, pressure transmitters, and flow meters perfectly. Thus, this analog input module delivers precise measurement for demanding industrial applications.
