PCH 1420 Vibration Monitor

Product catalog summary

Overview: The PCH 1420 Vibration Monitor is a sophisticated device designed for monitoring vibrations with multiple input channels and sensor compatibility. It supports various transducer inputs, including accelerometers, velocity sensors, and proximity probes, and is equipped for process and tacho inputs.

Specifications:

Input Channels: 6 channels, including 4 transducer inputs, 1 process input, and 1 tacho input.
Sensor Types: Supports accelerometers (10-1000 mV/g), proximity probes (0.8-8V/mm), velocity sensors (4-100 mV/mm/s), and PCH Mems sensors (10-333 mV/g).
Measuring Parameters: Includes mm/s, in/s, m/s², g, µm, mm.
Frequency Ranges: Default ranges from 1 Hz to 1500 Hz, with high-frequency bands up to 24 kHz.
Outputs: Up to 4 configurable outputs as DC or alarm relay drivers, supporting 4-20 mA, 0-20 mA, 2-10 V, or 0-10 V.

Features:

Real-time Monitoring: 4 real-time vibration channels with dual band and bearing fault detectors.
Safety and Compliance: Redundant safety and alarm relay, PL-d (SIL-2) compliant as per ISO/EN 13849-1.
Data Storage and Communication: Supports time waveform recordings, USB and RS-485 ports, and is ready for PCH Cloud and IoT integration.
Modularity: Can be supplemented with PCH modules like EtherBridge, Relay Box, Input Box, and Output Box.

Alarms and Relays:

Alarm Detectors: Configurable alert and danger alarms with adjustable limits and delay times.
Relay Options: Up to 24 additional relays can be connected via PCH Relay Boxes.
Safety Relay: Includes a galvanically isolated redundant relay for safety monitoring.

Environmental and Compliance:

Operating Temperature: -10 °C to +50 °C, with storage from -40 °C to +85 °C.
Compliance: CE, ISO 13849-1, ISO 10816/20816, VDI 3832, API 670, PL-d, ETL listed.

Additional Information: The PCH 1420 can be used in SIL-2 safety systems and is suitable for Ex applications with appropriate barriers. It requires a 24 V DC power supply and offers buffered outputs for local BNC connections.
