MODICON AS-B805-016

MODICON AS-B805-016 belongs to Modicon 800 series, a 16-point 115VAC discrete input module for PLC rack-based automation systems. It collects AC switch signals from field sensors and converts them into logic signals readable by the main CPU for logic judgment and sequence control. The input module receives on-site switch status, the AC signal supports 80-130VAC 47-63Hz field devices, and the automation signal collection realizes reliable signal acquisition for assembly lines and fastening stations.

The input module divides 16 channels into two groups of 8 points with independent electrical isolation to prevent interference spread between channels. It features indicator lights for each channel to show real-time on/off status for quick on-site inspection. The AC input circuit filters voltage fluctuation and noise, ensuring stable signal transmission of the input even in environments with motor start and stop interference. Engineers can connect limit switches, proximity sensors and pushbuttons to collect trigger signals for each automation step, and all input status is scanned and uploaded to the CPU for program execution and fault logic judgment.

This input module adopts single-slot plug-in design for standard Modicon backplane installation, saving cabinet space and supporting hot replacement during maintenance. The AC input circuit meets industrial anti-surge specification to resist transient voltage spikes. It supports fast signal response and status feedback to stabilize the whole automation workflow, shorten signal troubleshooting time and reduce production misjudgment caused by signal loss.
