Yokogawa 3500/15 133292-01 - 16-Channel Relay Module

Description:

The Yokogawa 3500/15 133292-01 is a 16-Channel Relay Module for the Yokogawa 3500 Machinery Management System. This module provides a high-density solution for alarm and shutdown functions within the rack. It features sixteen independent Form C (SPDT) relay contacts that can be configured to activate based on the status or alarm conditions from any other monitoring module in the same 3500 rack (e.g., vibration, temperature, or speed modules). Its primary function is to convert the system's logic into physical, hardwired relay outputs to initiate actions such as alerting plant personnel, starting auxiliary equipment, or executing a safe machinery shutdown. The high channel count makes it ideal for complex systems with numerous alarm points.

Application Scenarios

The 3500/15 16-Channel Relay Module is used in applications requiring a large number of discrete alarm and shutdown outputs from a single rack slot. Its key application scenarios include:

1. Complex Machinery Alarm Systems:

• Used on large turbomachinery trains (e.g., gas turbines, steam turbines) where multiple vibration points, temperatures, and speeds need individual alarm contacts for a central annunciator panel or DCS, providing operators with detailed fault location information.

2. Sequencing and Control Logic:

• Ideal for implementing complex interlock and sequencing logic. For example, it can be used to control the startup sequence of a lubrication oil system, where the main pump must start before an auxiliary pump is allowed to auto-start, and to trigger alarms for various system pressures and levels.

3. High-Density Shutdown Systems:

• Provides a compact solution for machinery with multiple, independent shutdown parameters. Instead of using multiple 4-channel relay modules, a single 3500/15 can consolidate many shutdown commands, saving valuable rack space.

4. Auxiliary System Monitoring:

• Perfect for monitoring all support systems for a major machine, such as seal oil systems, control oil systems, and cooling systems. Each potential fault (low pressure, high temperature, etc.) can be assigned its own relay channel.

5. Power Generation and Large Process Plants:

• Extensively used in power plants and refineries where a single rack might be responsible for protecting an entire unit and its associated auxiliary systems, requiring a high number of discrete output signals for control, alarm, and shutdown functions.
