BENTLY 3500/25 149369-01

Description

BENTLY 3500/25 149369-01 is an enhanced keyphaser module produced by Bently Nevada.This module is a dedicated device for providing keyphaser signals in machinery monitoring systems.The following is a detailed introduction to the module:

1.Main features

Signal conversion:Receives input signals from proximity probes or magnetic pickups and converts them into digital keyphaser signals.

Keyphaser signals:Indicate when a specific mark on a rotating shaft is aligned with the keyphaser sensor,which is critical for accurate timing measurements,including vector parameters such as shaft speed and 1X vibration amplitude and phase.

Processing capabilities:Has extended signal processing capabilities,which is improved compared to previous versions.

Compatibility:Maintains backward compatibility with existing keyphaser modules of traditional systems and can be seamlessly integrated into existing systems.

2.Technical specifications

Voltage and current:

Keyphase sensor power supply:-24Vdc,maximum 40mA per channel.

The operating voltage range may include:24VDC(18 to 36VDC),but the official documentation should be referred to for specific use.

Power consumption:3.2 watts typical,3.2W maximum possible.

Dimensions and weight:

Dimensions:119.9mm high,24.4mm wide,256.5mm deep(or described as 1U high,19 inches wide,2.5 inches deep,but note that these two descriptions may vary from source to source).

Weight:Approximately 0.34 kg(or described as approximately 3.5 kg,but the 0.34 kg here is more likely to refer to the weight of the module itself,not including packaging or accessories).

Operating temperature:

Typical operating temperature range:-30°C to+65°C(or-40°C to 85°C,but the specific range may vary depending on the use of internal safety barrier I/O modules or key phaser I/O modules).

Input and output:

Input signal range:+0.8V to-21.0V(non-isolated I/O modules)or+5V to-11V(isolated I/O modules).

Input impedance:21.8kΩminimum.

Input range:1 to 1200000 cpm(0.017 to 20kHz).

Output range:1 to 99999 cpm(0.017 to 1667Hz).

Output impedance:Maximum buffered output impedance 504Ω.

Number of channels:

In normal configuration,the system can accept up to four key phaser signals.

In paired configuration,up to eight key phaser signals(four main input channels and four backup input channels)can be accepted.

Response time:<1ms(but this data may vary depending on the specific application scenario and configuration).
