More Information

Overview Manuals Applications Relay Operation Monitoring & Control Safety & Compliance

Features:

  • Provides sixteen independently programmed SPDT relay channels.
  • Groups four relays at a time for normally energized or de-energized operation.
  • Uses alarm-drive logic configured through the 3500 Rack Configuration Software.
The current ordering configuration is 3500/33-01-01, the standard sixteen-channel relay output module with cNRTLus Class I Division 2 approval.

It converts programmable rack alarm logic into isolated relay contacts for shutdown, annunciation and auxiliary control circuits.

Before installation, verify rear I/O type, contact load, energized philosophy, alarm logic, field-source isolation, rack slot and approval drawing.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Drives machinery shutdown circuits from configured 3500 monitor alarms.
  • Provides annunciation contacts for control-room or distributed-control-system interfaces.
  • Operates auxiliary interlocks and alarm devices within the documented relay ratings.
  • Sixteen SPDT channels are arranged as four groups of four relays.
  • Each group is switched for normally energized or normally de-energized behavior.
  • Epoxy-sealed contacts include a standard 250 Vrms arc suppressor.
  • Alarm Drive logic combines selected monitor conditions into each relay command.
  • The channel alarm indicators show which programmed relay output is active.
  • TX/RX indication confirms communication with other modules in the 3500 rack.
  • The 01 suffix selects cNRTLus Class I Division 2 approval for the exact configuration.
  • Hazardous field conductors can remain exposed at the rear terminals during service.
  • Disconnect field power before removal and apply contact ratings appropriate to the installed area.
Description
3500/33-01-01 is the standard sixteen-channel relay output configuration for the Bently Nevada 3500 machinery protection system. Each channel is a programmable SPDT relay driven by alarm logic from monitor channels in the rack.

The module organizes the relays into four groups of four, with each group selectable for normally energized or normally de-energized operation. Front-panel indicators report module health, rack communication and individual channel alarm state.

This configuration applies relay logic to shutdown, annunciation and auxiliary control functions in machinery-protection installations. Contact ratings, field voltage, fail-safe philosophy, alarm-drive programming and rear I/O hardware must be verified before commissioning.

Technical notes
3500/33-01-01 can expose hazardous field voltage at the relay terminals; isolate every field source and verify zero energy before rear-I/O work.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What output hardware is selected by 3500/33-01-01?
Option 01 selects the standard sixteen-channel relay output module rather than the failsafe or low-current versions.
How are the relays grouped on 3500/33-01-01?
Four groups of four channels can each be selected for normally energized or normally de-energized operation.
Which rack function programs 3500/33-01-01 contacts?
The 3500 Rack Configuration Software assigns monitor alarms and logic conditions to each Alarm Drive output.
Can 3500/33-01-01 switch high-voltage loads directly?
Only within the documented standard-system and hazardous-area contact ratings; use interposing devices where the load exceeds them.
What must be isolated before changing 3500/33-01-01?
Disconnect every relay field source as well as rack power, then verify the rear terminals are de-energized.
What should be submitted for a 3500/33-01-01 relay review?
Provide the rack drawing, rear I/O number, contact voltages and currents, energized philosophy, approval area and programmed Alarm Drive matrix.
