Overview

The PT2060/90-A4-B4-H is a central Power Supply, Backplane Interface, and Signal Output module for ProvibTech monitoring racks. The -H suffix indicates High-Resolution data acquisition and processing, ensuring precise digital communication. It provides both stable backplane power and high-fidelity data from all inserted monitoring modules, simplifying integration with plant-level control networks.

Technical Data

Typical Applications

The PT2060/90-A4-B4-H is ideal for mission-critical systems requiring high digital measurement accuracy, including:

• Steam turbines and high-speed gearboxes

• Refinery compressors

• Advanced condition monitoring systems with spectral analysis and fault detection

The -H feature ensures that the RS-485 digital output provides high-resolution data, serving as the primary source for plant condition monitoring.

FAQ

Q1: How does the High-Resolution (-H) feature apply?
A: It ensures that data collected from monitoring modules and transmitted via RS-485 maintains high digital resolution, improving trend analysis and diagnostic accuracy.

Q2: What is the primary function of the A4 (RS-485) output?
A: Enables a master system (DCS or SCADA) to retrieve all measurements and alarm status flags digitally using Modbus RTU.

Q3: Does the B4 output provide raw sensor data?
A: B4 provides a buffered voltage signal for raw, unfiltered vibration signals, suitable for oscilloscopes or data recorders.

Q4: Can this module run the entire monitoring rack?
A: Yes, it converts AC input to 24 VDC backplane power to run all monitoring, relay, and communication modules in the rack.
