Yokogawa AMN34 Multipoint Analog I/O Module Rack
Product Introduction
The AMN34 is a multipoint analog input/output module rack designed for seamless integration with Yokogawa’s CENTUM® VP and CENTUM® CS 3000 distributed control systems. It houses up to eight analog I/O modules in a single 450 × 200 × 100 mm chassis, providing high-channel density and centralized wiring for field signals. Equipped with a robust backplane for power distribution and data communication, the AMN34 ensures deterministic performance and easy module replacement without disrupting the control network.
Key Applications
Continuous monitoring of sensor signals—such as temperature, pressure, flow, and level—in petrochemical and chemical processing plants.
Control of analog actuators—valves, dampers, and variable frequency drives—in power generation and utilities.
Batch and continuous dosing in water and wastewater treatment facilities, with precise analog control loops.
Environmental monitoring and regulation in pharmaceutical and food & beverage production.
Distributed analog I/O extension for remote skids and offshore platforms where space is at a premium.
Brand Overview
Yokogawa has led the process automation market since 1915, offering world-class DCS platforms, field control stations, and I/O hardware. Renowned for reliability and long product lifecycles, Yokogawa supports critical industries with comprehensive services and technology innovations.
Product Advantages
-
High Channel Density: Supports up to eight analog I/O modules in a compact 4U-equivalent rack, reducing cabinet footprint.
-
Hot-Swap Capability: Individual I/O modules can be replaced without powering down the rack, ensuring continuous operation.
-
Robust Backplane: Provides redundant 24 V DC power distribution and deterministic communication for precise sampling.
-
Simplified Wiring: Centralized field terminal blocks minimize cable runs and ease maintenance.
-
Diagnostics and Status: Front-panel LEDs indicate rack health, module status, and communication faults for rapid troubleshooting.

Frequently Asked Questions (FAQ)
Q: How many I/O modules can AMN34 hold?
A: The AMN34 chassis accepts up to eight analog I/O modules in a single rack.
Q: Can I replace modules without shutting down the rack?
A: Yes, each module is hot-swappable, allowing maintenance without system interruption.
Q: What power supply voltage is required?
A: A redundant 24 V DC supply (±10 %) is required for the backplane.
Q: Are channels isolated?
A: Yes, each channel is isolated up to 1500 V DC from the backplane to prevent ground loops.
Q: What analog ranges are supported?
A: Configurable for ±10 V or 0–20 mA on both input and output modules.
Q: What is the sampling rate per channel?
A: Each channel can be sampled as fast as every 20 ms.
Q: How is module status indicated?
A: Front-panel LEDs show module presence, error, and warning conditions.
Q: Can I mount the rack on a panel?
A: Yes, the rack includes brackets for DIN-rail or panel mounting.
Q: What environmental conditions can it withstand?
A: Operating from 0 °C to 55 °C and 10 %–90 % RH (non-condensing).
Q: How much does the empty rack weigh?
A: The chassis weighs 2.5 kg without I/O modules installed.
