Bently 3500-93 135785-01 System Display Interface Module

Description

Hardware & Electrical Specifications

‑ Manufacturer: Bently Nevada (Baker Hughes) ‑ Compatible System: 3500‑05 full‑size / mini rack, mandatory pairing with 3500/22M TDI module ‑ Functional Type: System Display Interface Module (DIM) for 3500/93 Local Operator Display Unit ‑ Communication Interfaces:  ‑ Serial: RS‑422 (to display unit, via matched rear I/O card) ‑ Supported Protocols: Bently proprietary display protocol ‑ Max quantity per rack: 1 piece only ‑ Max cable distance to display unit: 100 ft (30 m) ‑ Typical power consumption:5.8 W, powered by rack backplane bus ‑ Front‑panel Indicators: OK LED, TX/RX LED ‑ Matching Parts: Main‑board 135785‑01 must pair with rear I/O 135801‑01, sold separately ‑ Hot‑swap: Supports hot‑swap; local‑display function lost during replacement; machinery‑protection trip logic remains fully operational. ‑ PCB Coating: Conformal coated for harsh industrial cabinet environment ‑ Safety Certification: CE, CSA hazardous‑area approvals available

Mechanical Data

‑ Dimension(H×W×D):241.3 mm ×24.4 mm ×241.8 mm ‑ Weight: approx 0.82 kg

Core Functions

1. Rack‑to‑display data bridge: Collect full‑rack monitor‑module measurements, alarm status, fault codes and event history, transmit to 3500/93 local display panel for on‑site operator viewing.
2. Local human‑machine interface support: Enable on‑site operators to view channel values, alarm lists, event logs, rack health status without PC workstation.
3. Protection‑safety isolation: DIM hardware failure will not impact hardware trip logic of all monitor modules; machinery‑protection function remains intact.
4. Self‑diagnosis: Detect backplane communication fault, serial‑link fault to display unit; report module hardware fault to rack‑system log.

Installation, Replacement & Critical Warnings

1. Supports hot‑swap; local‑display operator interface is lost during plug‑pull, but machinery‑protection trip function is unaffected.
2. Compatibility warning: ‑ Must use matched rear‑I/O 135801‑01; cannot interchange main‑board / rear‑I/O with 3500/91 / 91M / 92 gateway modules. ‑ Front‑mount display application requires install DIM in slot‑15 (rightmost slot) of full‑size rack; remote‑mount display allows any available slot except slot‑15 restriction. ‑ Only one 3500/93 DIM can be installed in single rack; must cooperate with 3500/22M TDI module. ‑ Verify rack firmware version compatibility before replacement.
3. After replacement, check OK LED status; download rack configuration project, verify serial communication link to display unit, confirm real‑time data and alarm indication on local display panel.

4. Common failure mode: Serial‑interface circuit damage, component aging; serial cable fault will cause local‑display blank / no‑data, will not trigger machinery‑protection trip.
