Signal Conditioning and Loop Power
The Schneider DAW 105 includes built-in 24V DC loop power for each channel. You do not need external power supplies for two-wire transmitters. The module uses a passive low-pass filter for noise rejection. This filter removes high-frequency interference from your measurements. Consequently, you get stable readings in industrial environments.
Energy Storage and Protection
This input module includes capacitor arrays for transient protection. Each channel stores 0.1 microfarads for current spike absorption. The module withstands continuous overcurrent up to 40mA without damage. Additionally, the board features input clamping diodes for ESD protection. These features safeguard the module during wiring errors or surges.
Interface and Connectivity
The Schneider DAW 105 uses screw-type terminal blocks for field wiring. The blocks accept 14-22 AWG wire easily. Each channel provides two terminals for signal positive and negative. Eight LED indicators show channel activity and overload status. You can diagnose wiring problems without special tools.
Component Layout and Construction
The Schneider DAW 105 contains 95 discrete components on a four-layer PCB. Key parts include eight 12-bit ADC chips and 16 operational amplifiers. An onboard microcontroller manages all conversion and communication tasks. All components meet industrial temperature ratings from 0°C to +55°C. This robust construction ensures reliable operation for many years.
Integration and Compatibility
Use the Schneider DAW 105 with any compatible Schneider PLC or DCS system. It works alongside DAW 106 output modules and accessories.
