Product Overview

The PREDICTECH TM302-A01-B00-C00-D00-E08-F00-G00 is an advanced dual-channel vibration monitor and protection relay designed for continuous machinery monitoring in industrial environments. This unit accepts inputs from various sensor types, such as accelerometers or velocity probes, and processes these signals to compare the derived vibration levels with user-defined limits. A standout feature of this module is the inclusion of two independent alarm relay outputs (denoted by the E08 code), providing comprehensive protection for critical machinery. This DIN-rail mounted module offers both local machine protection and analog data output for seamless integration with a plant's DCS or PLC. Its ability to monitor two independent channels makes it a highly versatile and cost-effective solution for safeguarding industrial assets.

Technical Data

The TM302-A01-B00-C00-D00-E08-F00-G00 monitor is engineered for high reliability, offering precise signal conditioning and fast alarm response times, which are crucial for machinery safety. Its dual-channel configuration allows for the simultaneous monitoring of two machine points or two separate machines, ensuring comprehensive protection. The A01 configuration supports inputs from accelerometers or velocity probes, measuring vibration velocity or acceleration. The E08 code indicates the inclusion of two independent alarm relay outputs, which can be used to trigger alerts or shutdowns based on vibration thresholds. This combination of features ensures both early warning and critical shutdown capabilities, minimizing the risk of machine failure.

Parameters

Typical Applications

The TM302 is ideally suited for monitoring critical machinery, particularly when continuous monitoring of vibration levels is required. It can monitor two separate machine points (e.g., drive-end and non-drive-end bearings of large industrial motors or pumps) using a single module. The inclusion of two dedicated alarm relays ensures that when vibration levels exceed predefined thresholds, appropriate actions, such as sounding alarms or shutting down the machine, are automatically triggered. This module minimizes the complexity and cost of safeguarding industrial assets, offering dual-channel monitoring with robust protection features.

Frequently Asked Questions (FAQ)

Q1: What does the E08 code signify on the TM302 monitor?

A: The E08 code specifies the inclusion of two independent alarm relay outputs. These relays enable the module to provide automatic protection functions, such as sounding alarms or initiating a machine trip, when vibration levels exceed predefined thresholds.

Q2: Can the two channels be set to monitor different vibration levels?

A: Yes, each of the two channels operates independently. You can set distinct alert and danger setpoints, time delays, and sensor sensitivities for each channel to match the specific characteristics of the monitored machine points.

Q3: Does the TM302 require a separate signal conditioner for accelerometers?

A: No, the A01 configuration implies that the TM302 includes the necessary integrated constant current source (IEPE/ICP power) to directly power and condition signals from standard accelerometers.

Q4: How does the 4-20 mA output integrate with the plant's control system?

A: The two 4-20 mA outputs provide continuous, proportional analog signals representing the overall vibration level of each channel. These outputs can be directly wired to a PLC or DCS, enabling operators to trend vibration data over time for predictive analysis and real-time monitoring.
