Product Overview

The YOKOGAWA AMM22 module functions as a Multiplexer Input Module, designed to handle a large number of analog input signals through a single internal analog-to-digital converter (ADC) using time-division multiplexing. This essential YOKOGAWA component offers a cost-effective solution for monitoring numerous field devices, especially those with relatively slow-changing signals (e.g., temperature, level).

By integrating the AMM22 into your control system, you can increase I/O density within the chassis, thereby maximizing space and resource utilization.

Detailed Technical Specifications of the AMM22

The YOKOGAWA AMM22 multiplexer input module typically provides a high number of input channels, often 32 channels or more, which are sequentially sampled by the internal ADC.

Multiplexing Principle and Application

The core of the AMM22 is its multiplexing capability, which connects multiple input channels sequentially to a single ADC. While this design limits the effective sampling rate per channel (making it unsuitable for very fast processes), it significantly reduces the cost per channel.

This module is ideally suited for monitoring large numbers of process measurements that do not change rapidly, such as:

• Tank levels

• Oven temperatures

• Flow totalization

Frequently Asked Questions (FAQ)

Q1: What is the main advantage of the AMM22 Multiplexer Input Module?

A1: The main advantage is its high channel density at a lower cost per point, making it ideal for applications that require monitoring a large number of slower-changing analog variables.

Q2: How many input channels does the AMM22 typically provide?

A2: The AMM22 typically provides a high number of input channels, often 32 or more.

Q3: Is the AMM22 suitable for high-speed signal acquisition (e.g., vibration)?

A3: No, due to its multiplexed scanning principle, the effective sampling rate per channel is low. Therefore, it is not suitable for high-speed or dynamic signals like vibration.

Q4: What is your policy if the module has a quality issue upon arrival?

A4: We support a 30-day return window if there are any quality issues with the YOKOGAWA AMM22 module.
