ABB DX581-S Safety Digital Sensor

Product Information

• Signal Types and Channels1: It features 8 safety digital input channels (SDI), with 8 SDI reaching SIL2 level and 4 SDI reaching SIL3 level with discrepancy time monitoring. There are also 8 safety digital output channels (SDO), all of which are 24V DC, 0.5A, reaching SIL3 level. In addition, there are 4 pulse output channels for system diagnostics and control.
• Electrical Characteristics3: The input voltage is 24V DC, and the output voltage range is 20.4 - 28.8V DC. The input current is 7mA, and the maximum output current per output channel is 0.5A.
• Communication Interface6: It adopts the ProfiNet communication interface and can work with communication modules such as CI501 - PNIO, CI502 - PNIO, CI504 - PNIO, and CI506 - PNIO to achieve remote I/O control.
• Degree of Protection3: With IP20 protection, it can prevent contact with solid objects of 12mm or more.

Product Attributes

• Physical Dimensions3: It is 67.5mm wide, 76mm high, and 62mm long.
• Weight3: The net weight is 0.13kg, and the gross weight is 0.159kg.
• Environmental Conditions6: The standard version operates at a temperature range of 0°C - 70°C. The XC (extreme condition) version has a wider temperature range of - 40°C - + 70°C, higher vibration resistance, capable of withstanding 4g rms vibrations (up to 500Hz) and 2g sinusoidal vibrations (up to 500Hz), and meets more stringent EMC requirements.

Core Functions

• Safe Input and Output: It provides high - safety - rated digital input and output functions, ensuring reliable operation in industrial environments. It can be used to control safety - related equipment such as emergency stop buttons and safety door switches.
• Diagnosis and Monitoring: Through the 4 pulse output channels, it enables system diagnosis and monitoring functions, allowing users to promptly detect faults and abnormal situations in the system.
• Flexible Configuration: The input filter can be configured between 1 - 500ms to adapt to different industrial field environments and signal requirements6.
• Electrical Isolation: Each module has electrical isolation, which can effectively prevent external electrical interference and improve the stability and reliability of the system.
