Overview
The PDM1201-A50-B1-C0-D1-E0-F0 is a dual-channel vibration monitor for critical machinery. It accepts velocity or accelerometer signals, calculates overall vibration levels, and compares them against user-defined thresholds to trigger alarms. The module provides both analog 4–20 mA outputs for trending and dedicated relay outputs for instantaneous protection. The A50 code indicates high-temperature compatibility for the sensor inputs.
Technical Data
| Parameter | Specification |
|---|---|
| Model Number | PDM1201-A50-B1-C0-D1-E0-F0 |
| Product Type | Dual-Channel Vibration Monitor / Transmitter |
Typical Applications
The PDM1201 is used for casing vibration monitoring on essential rotating machinery, such as:
-
Drive-end and non-drive-end bearings of large electric motors
-
Gearboxes
-
Cooling tower fans
Its two dedicated alarm relays manage protection logic independently, interfacing directly with machine control circuits for safe shutdown if vibration limits are exceeded. The module ensures cost-effective, continuous protection of critical components.
FAQ
Q1: What is the main function of the two 4–20 mA outputs (B1)?
A: They transmit the overall vibration level of each channel to a plant DCS or PLC for trending and historical data.
Q2: How are the two alarm relays (D1) typically configured?
A: One is configured as an Alert alarm (elevated condition), and the other as a Danger/Trip alarm (initiates machine shutdown).
Q3: What does the A50 code indicate?
A: It designates compatibility with high-temperature sensors (e.g., up to 120°C) for accurate signal conditioning.
Q4: Can this monitor be used with proximity probes?
A: No, this configuration is for velocity/acceleration sensors. Proximity probes require a different monitor (e.g., PDM1202) and a separate driver.
