3BSE018291R1 DSAX 110A ABB | Analog Input/Output Board 8/8

Description

The 3BSE018291R1 DSAX 110A is an analog input/output board from ABB, featuring 8 analog input channels and 8 analog output channels, categorized as an I-O module. Its physical dimensions are 324 mm in depth/length, 234 mm in width, 18 mm in height, with a net weight of 0.5 kg. The board has an open-ventilated plastic enclosure that supports efficient heat dissipation. It is equipped with at least three front-panel LEDs for status indication: fault, run, and warning, enabling quick visual monitoring of module operation. Key protective features include mechanical keying on the module and MTU, which prevent insertion into positions where excessive voltage or current could cause damage, plus an integrated identification ID that stops misinstallation; if the module ID does not match the system configuration, the ModuleBus host defines the module type. It supports both single-module and redundant module applications for flexible system design. The board has inherent resistance to power line interference; for high-reliability environments or areas with severe power interference, a shielded isolation transformer can be installed to reduce ground-related interference. When using an external DC power supply for inputs, a regulated DC power supply is recommended to avoid false signals caused by ripple from unregulated rectified filter power supplies.
