NEW 6ES7521-1BH00-0AB0

Key Specifications and Features:

• Channel Configuration: Equipped with 8 digital input channels, grouped into two groups of 4, enabling efficient monitoring of multiple digital signals from sensors, switches, or other industrial components.
• Input Characteristics: Each channel accepts 24V DC input signals, supporting both sinking (NPN) and sourcing (PNP) input circuits for versatile connectivity. The input voltage range typically spans 0V to 30V DC, with a minimum ON voltage of 15V DC and maximum OFF voltage of 5V DC, ensuring reliable signal detection.
• Diagnostics and Monitoring: Incorporates comprehensive diagnostic functions, including wire breakage detection, short-circuit monitoring, and overvoltage protection for each channel. These features facilitate quick identification of faults, minimizing system downtime in industrial processes.
• Isolation: Provides electrical isolation between channel groups, as well as between the channels and the backplane bus. This isolation enhances noise immunity and protects the S7-1500 controller from voltage spikes or electromagnetic interference (EMI) commonly encountered in industrial environments.
• Power Supply: Operates on a 24V DC power supply (19.2V DC to 28.8V DC) with reverse polarity protection to prevent damage from incorrect wiring. The maximum current consumption from the external supply is 120mA, with a backplane bus power consumption of 0.6W.
• Switching Performance: Offers responsive operation with a typical input delay of ≤1.2ms (in standard mode) and configurable filter times (0.05ms to 100ms) to suppress noise, ensuring stable signal detection in harsh industrial settings.
• Environmental Ratings: Designed to withstand demanding industrial conditions, with an operating temperature range of -30°C to 60°C for horizontal mounting and -30°C to 40°C for vertical mounting. It supports installation at altitudes up to 5000m, with derating requirements for altitudes above 2000m.
• Mechanical Details: Dimensions are 35mm (width) × 129mm (depth) × 147mm (height), with a weight of approximately 230g. Front connectors (screw-type or push-in type) are sold separately, allowing users to choose based on their wiring preferences.
• Integration: Seamlessly integrates with the S7-1500 backplane bus and is configurable via Siemens TIA Portal software, simplifying setup, programming, and integration into automation systems.
