Installation & Field Application Guide

  • Install the Keyphasor module in any half-height front slot of the 3500 rack. The I/O module occupies the corresponding rear slot.
  • For Internal Barrier I/O, observe the reduced operating temperature range of 0°C to +65°C. Ensure adequate cabinet cooling.
  • Use shielded twisted-pair cables for Keyphasor signal wiring. Maintain a minimum bend radius of 10x cable diameter.
  • In hazardous area installations (ATEX/IECEx), ensure proper cable glands and sealing per local certification requirements.

Why Choose the 3500/25-01-03-02

  • Provides precise Keyphasor pulses for accurate speed and phase measurement.
  • Internal Barrier I/O eliminates the need for external safety barriers in hazardous areas.
  • ATEX/IECEx/CSA certification allows installation in Class 1 Zone 2 environments.
  • Compact half-height design saves rack space while delivering 2-channel capability.

Field Engineer FAQs

Q1: What is the difference between standard I/O and Internal Barrier I/O?

A1: Internal Barrier I/O includes built-in galvanic isolation and zener barriers for hazardous area installations. This eliminates the need for external safety barriers but reduces the operating temperature range to 0°C to +65°C.

Q2: How many Keyphasor channels does this module provide?

A2: The 3500/25-01-03-02 provides 2 Keyphasor channels on a single half-height card. Each channel accepts a proximity probe or magnetic pickup input.

Q3: What is the recommended sensor type for Keyphasor input?

A3: Bently Nevada recommends 3300 XL 8mm proximity probes or magnetic pickups with a voltage output between -0.8V and -21V DC. Ensure the sensor is properly gapped per the installation manual.
