Yokogawa AMM12 Voltage Input Multiplexer Module

AMM12 Advantages

Yokogawa AMM12 provides high-density multi-point voltage signal centralized multiplexing acquisition solutions for Yokogawa Centum VP series control systems. Stable operating performance. Low-loss signal multiplexing switches guarantee tiny signal attenuation during multi-path voltage scanning, independent isolated channel design eliminates cross-channel signal crosstalk and measurement deviation; dual redundant seamless automatic switching ensures continuous voltage parameter monitoring when single module fails, built-in full-time channel circuit self-check function timely uploads open-circuit and overvoltage abnormal alarms, fully meeting long-term uninterrupted high-density voltage signal monitoring demands of power plant and chemical production lines. Strong environmental adaptability. Reinforced anti-vibration industrial PCB substrate and built-in multi-stage isolation circuits support 24-hour continuous operation under humid, dusty, high-temperature and heavy electromagnetic interference industrial cabinet working conditions. Excellent anti-interference capability. Complete channel-to-channel galvanic isolation blocks power grid surges and cable crosstalk interference; dedicated surge suppression circuit protects multiplexing signal channels from abnormal PT voltage impact, fundamentally eliminates sampling distortion and measurement error induced by field high-voltage electromagnetic noise. Perfect system compatibility. Standard nest base slot and ESB backplane bus gold finger interface fully match all mainstream Yokogawa Centum VP series functional modules including AMN11-S1 nest base units, AAM11 current voltage input modules, CP471-00 processor modules and ADM11 power supply modules, realizing unified multi-point voltage signal convergence inside remote FIO racks. Convenient maintenance design. Compact plug-in structure equipped with multiplexing scanning, running status and channel fault alarm indicator lights, supports independent hot swap without rack power cut-off, simplifies on-site multi-point voltage secondary wiring inspection, scanning cycle parameter debugging and rapid spare parts replacement. Industrial durable reliability. Manufactured strictly in accordance with Yokogawa industrial DCS power measurement board production standards, built-in full-time self-diagnosis covering all multiplexing channels and bus links, fully satisfying long-term stable multi-path voltage signal multiplexing acquisition operation demands of on-site Centum VP control systems.
