Overview
The PT2060/91-A0 serves as the head-end or System Interface Module (SIM) of a ProvibTech monitoring rack, consolidating three key functions:
-
Power Conversion: Converts wide-range AC input (90–264 VAC) into regulated +24 VDC, distributing power via the backplane to all monitoring modules.
-
Digital Communication: Provides RS-485 (Modbus RTU) interface (
A0) for external control systems like SCADA or DCS. -
Data Concentrator: Collects measurement and status data from all individual channels and prepares it for digital transmission.
This module is essential for clean power delivery and centralized data access across the entire monitoring architecture.
Technical Data
| Parameter | Specification |
|---|---|
| Model Number | PT2060/91-A0 |
| Product Type | Integrated Power Supply and System Interface Module (SIM) |
Typical Applications
The PT2060/91-A0 is mandatory for rack-based machinery protection systems and mission-critical monitoring, including:
-
Steam and gas turbines
-
High-speed compressors
-
Critical pumps
It powers the rack, consolidates data, and provides reliable RS-485 communication for real-time monitoring and alarm retrieval via centralized control systems.
FAQ
Q1: How does PT2060/91-A0 differ from individual monitoring modules?
A: The /91-A0 module powers the entire rack and manages communication, while individual monitoring modules perform sensor signal conditioning and measurement.
Q2: What communication protocol does the A0 output use?
A: RS-485 physical layer, typically Modbus RTU, for PLC or DCS integration.
Q3: Does this module provide alarm relay outputs?
A: No, alarm relays are handled by separate Relay Output Modules powered and controlled by the SIM.
Q4: Does the module accept AC or DC power?
A: It accepts wide-range AC (90–264 VAC) and converts it internally to +24 VDC for the rack backplane.
