The 3500/93 135799‑01 Display Interface Module is part of the 3500 Machinery Protection System. Its role is to provide local or remote visual indication of the system status, alarms, events, and channel/module data for machinery protection racks. It allows operators and maintenance staff to view real‑time and historical data such as alarm event lists, system event lists, module status, channel outputs, Keyphasor or Tachometer data etc.
This Display Interface Module (DIM) works together with a display unit. Each DIM connects to the display, sending formatted data collected from the 3500 rack. The display can be mounted in several ways: face‑mounted on the rack front, panel mounted, in a 19‑inch EIA rack, or independent mounting. Up to two displays may be connected per 3500 rack, each requiring its corresponding DIM.
It is designed for harsh industrial conditions, giving reliable visibility into system behavior, alarms, and machine health, aiding in diagnostics, maintenance planning, and safe operation.

Allows real‑time visibility into the status of the entire 3500 Machinery Protection System: channel data, event lists, alarms, etc., without needing to access backend software.
Flexible mounting: can be front‑rack mounted, panel, 19‑inch rack, or independently mounted. This gives installation flexibility in many control room layouts.
Up to two displays per 3500 rack: gives redundancy or allows multiple operators to view data.
Modest power consumption (~15.5 W total) makes it reasonably efficient for displays of this capability.
Rugged enough for industrial conditions: temperatures, humidity, etc., within ranges appropriate for machinery protection use.
Improves safety and maintenance: by giving operators awareness of anomalies or alarms more quickly, enabling faster response.
The 3500/93 135799‑01 is suited to any installation of large rotating machinery or critical process equipment where machine protection is required. Specific applications include:
Power plants: turbines, generators, auxiliary equipment needing condition monitoring.
Petroleum & gas: compressors, pumps, rotating machinery in refineries or offshore platforms.
Chemical / petrochemical plants: safety, alarm event tracking, diagnostics.
Mining / metals: large motors, crushers, mills, conveyor belts.
Manufacturing: heavy machinery, reduction of unplanned downtime by real‑time monitoring.
Utilities / water treatment: critical pumps & motors whose failure leads to large impact.

Q1: What exactly does the 3500/93 135799‑01 Display Interface Module display?
A1: It displays system event lists, alarm event lists, module and channel data, Keyphasor and tachometer data; basically all status and measurement information that resides in the 3500 rack pertinent to machinery protection.
Q2: How many displays can be connected to one 3500 rack using this module?
A2: Up to two displays per rack are supported. Each display requires its own Display Interface Module slot.
Q3: What are the mounting options for the display and display interface?
A3: The display can be face‑mounted directly on the front of the 3500 rack, mounted in a 19‑inch EIA rack, panel mounted, or mounted independently (e.g., on a wall or panel).
Q4: What are its dimensions and weight?
A4: The module measures about 263 × 58 × 28 mm and weighs approximately 0.8 kg.
Q5: What are its operating and storage temperature ranges?
A5: It operates approximately between ‑30 °C to +65 °C, with storage down to about ‑40 °C up to +85 °C.
Q6: How much power does it consume?
A6: Combined Display + Interface can draw up to ~15.5 watts; display alone (for certain display unit variants) may draw ~5.6 W or ~12.0 W depending on unit.
Q7: Is it compliant with any industrial standards?
A7: Yes, it is designed to meet requirements such as API Standard 670 (machinery protection) for reliability, visibility, and safety.
Q8: What happens if this display module fails? Does it affect machinery protection?
A8: If the display or interface fails, you lose visual feedback locally/remote of status and alarms, but the core protection mechanisms in the 3500 rack modules (alarms, shutdowns, relays) continue to operate if they are otherwise unaffected.
Q9: Can it be used in harsh environments (e.g. high humidity, dust, vibration)?
A9: Yes, the module is built for industrial/harsher conditions. Specified humidity up to ~95% non‑condensing, and environmental tolerances typical for protection equipment. But mounting, enclosure, environmental sealing should be considered in design.
Q10: How is configuration done?
A10: Using the 3500 Rack Configuration Software you set up what events, channels, alarm thresholds etc. are visible via the interface, and set display and interface settings. Communication between DIM and Display via front or rear rack I/O as required.
