Product Introduction

Dual channel design: The 3500/25 module has two input channels that can receive Keyphasor signals 12 from two different sensors.

Digital signal conversion: This module is capable of converting received analog key phase signals into digital signals for subsequent processing and monitoring.

High precision timing measurement: The 3500/25 module can provide accurate timing measurement for measuring shaft speed and vector characteristics, such as

1X vibration amplitude and phase 12, through each rotation or multiple event pulses (key phase signals) of the rotating shaft or gear.

Backward compatibility: The 3500/25 module provides higher Keyphasor signal processing capabilities than previous designs while maintaining full backward

compatibility with existing Keyphasor modules used for legacy systems in terms of shape, fit, and functionality.

Multiple configuration options: Users can choose different configuration options according to their actual needs, such as insulated I/O modules and non

insulated I/O modules.

Application scenarios

The 3500/25 module is widely used in various industrial monitoring and control systems, especially in situations where precise measurement of shaft speed and

vector characteristics is required. For example, it can be used for vibration monitoring, position monitoring, and speed control of rotating machinery.

Technical specifications and installation requirements

Input signal range: The input signal range for non insulated I/O modules is+0.8V to 21.0V, while for insulated I/O modules it is+5V to -11V. Signals beyond this

range will be subject to internal limitations of the module.

Output impedance: The maximum output impedance of the buffer is 504 ohms.

Power requirements: The power supply for the key phase sensor is -24Vdc, with a maximum of 40mA per channel.

Installation requirements: In order to be installed in the full height slot, the half height main module requires a unique installation adapter, and users can

insert the main module into any of the 14 accessible slots
