ABB DSDI 110AV1 Digital Input Board 32 Channels

Description

The ABB DSDI 110AV1 (3BSE018295R1) Digital Input Board is a high-performance 32-channel digital input module designed for industrial automation systems, part of the ABB S7 series I/O modules. Its core function is to convert external digital signals from devices like switches, NPN/PNP sensors, and relay contacts into signals recognizable by PLCs or other control systems, enabling reliable signal collection, conversion, and transmission. Key technical specifications include 24V DC input voltage, 32 input channels, support for Profibus DP communication protocol, and an output frequency of 50 kHz. It operates in a temperature range of -20 degrees Celsius to 60 degrees Celsius, with a protection rating of IP67, and features a compact form factor with dimensions typically 234mm x 18mm x 229.5mm and a weight of approximately 400g. Equipped with DIN rail mounting for easy installation and maintenance, the module offers industrial-grade reliability for harsh environments, plus additional functions like signal filtering and amplification. It also includes diagnostic indicators to detect potential input signal faults, and meets IEC 61508, IEC 60947-5-5, CE, and UL certification standards. Ideal for diverse industrial control scenarios, it supports applications in motion control, packaging machinery, food processing equipment, conveyor systems, and safety interlock systems.
