The Schneider Electric AS-B357-001 serves as a specialized discrete input module, ideal for digital signal processing in various applications. This module operates at a standard voltage rating of 24 volts DC, with a tolerance of ±10%. It is equipped with eight isolated input points that can effectively interact with 24V DC sensors and actuators. The input configuration supports both sinking and sourcing types, making it versatile for different setups.

Each input point has a typical current capacity limited to 5 mA at 24V DC, ensuring low power consumption. For enhanced protection, the module provides an isolation rating of 1500V AC between its channels and logic side. This rating facilitates safe integration of external devices with minimal risk of interference or damage.

The operational temperature range extends from -25°C to +60°C (-13°F to +140°F), accommodating a variety of industrial climates. The AS-B357-001 can also operate within 5% to 95% non-condensing relative humidity, which is important for reliable performance in different environments. This module is designed for mounting on standard DIN rail (TS35), allowing for simple and effective installation in control panels or cabinets.

Additionally, the device maintains specific voltage thresholds for ON and OFF states, with an ON-State voltage exceeding 70% of the source voltage and an OFF-State voltage dropping below 30% of the source voltage. Overall, this discrete input module is a robust and reliable solution for integrating digital input signals into automated systems.
