Bently Nevada 136703-01 is a 3500/50 I/O Module with Internal Barriers and Internal Terminations, and it is a spare part related to 3500 internal barriers.
This module is a 3500/50 input/output module with internal barriers and internal terminations. Its related 3500/50 Tachometer Monitor is one of the compatible monitors. Meanwhile, if the 3500/50 I/O module is of the type with internal barriers, the external termination option is not available because hazardous area approvals do not allow the use of intrinsically safe wiring within a multi-cored cable assembly. In addition, the 3500/50 monitor requires firmware version 1.05 E or later to work with internal barriers.
Functional Characteristics of Bently Nevada 136703-01
Measurement Function: As a 3500/50 tachometer module, it has 2 channels, can receive inputs from proximity probes or magnetic sensors, measure shaft speed, rotor acceleration or direction, and compare with preset alarm values to trigger an alarm when exceeding the limit.
Signal Processing: It can provide processed keyphasor signals for the 3500 rack backplane; has a peak hold function, which can store the maximum forward and reverse speeds, the number of reversals and reset the peak value.
Electrical Parameters of Bently Nevada 136703-01
Bandwidth: 30 kHz.
Input Type: Proximity, magnetic or other compatible sensors.
Output Signal: 4-20 mA analog quantity and digital output compatible with 3500 system.
Power Supply: 10-30 Vdc or 12-24 Vdc.
Environmental Parameters: Operating temperature ranges from -40 °C to +85 °C.
Bently Nevada 136703-01 is used for condition monitoring and protection of various machinery. Its related internal barriers provide explosion protection for transducer systems connected to the 3500 Machinery Protection System, and are suitable for installation scenarios of various transducer systems in hazardous areas.
