Product Overview
The Yokogawa ADV161-P00 S2 Digital Input Module is a high-density 64-channel discrete input module designed for use in Yokogawa CENTUM Distributed Control Systems (DCS). It is used to acquire ON/OFF signals from field devices such as switches, sensors, relays, and contact-based instruments.
Unlike the ADV151 series (32 channels), the ADV161 series is designed for higher channel density applications, making it suitable for large-scale plants that require maximum input capacity, reduced cabinet space, and efficient I/O consolidation.
The S2 suffix typically indicates a specific system or functional configuration variant used in CENTUM/ESB/FIO architectures.
