Product Description

Description

The 3500/33 with spare part number 149986-01 is a full-height module that provides 16 independent programmable relay outputs for machinery protection and control switching. This 3500/33 149986-01 module functions within the 3500 Series Machinery Protection System and installs into any standard slot to the right of the Transient Data Interface (TDI) module. Each relay output features independent voting logic configuration and dedicated Alarm Drive Logic, which processes alert, danger, and Not-OK statuses derived from any combination of monitor channels across the rack via the configuration software. Internal communication link tracking is visually monitored via integrated front panel status indicators.

Features

16 fully independent single-pole double-throw (SPDT) relay output channels.
Custom voting logic and Alarm Drive Logic supporting complex AND/OR logic configurations.
Integrated onboard 250 Vrms arc suppressors installed as a standard protection feature.
Switch-selectable operations for Normally De-energized (ND) or Normally Energized (NE) modes in groups of four channels.
Visual status verification via OK, TX/RX, and individual channel alarm LEDs.

Applications

Automated machinery trip and emergency shutdown logic initialization.
Interlocking and annunciator panel control in heavy industrial processing.
Critical alarm state relay signaling for turbines, large pumps, and industrial compressors.

Installation Guidelines

Slot Placement: Seat the full-height main control module into any available chassis slot located directly to the right of the primary TDI module.
Redundant Pairs: Pair the main front-panel module with its corresponding 16-channel relay I/O module positioned directly behind it in the rear chassis space.
Logic Programming: Configure the voting logic structures and operational parameters via the 3500 Rack Configuration Software prior to putting the instrumentation loop online.
Operation Mode Setup: Set the physical switches to select between Normally De-energized (ND) and Normally Energized (NE) setups for each four-channel group based on plant safety specifications.
Hazardous Voltage Warning: Ensure all field terminal wiring points are completely isolated from source power lines prior to installation or maintenance to eliminate high-voltage shock risks.
Explosion Hazard Precaution: Do not connect or disconnect any components or field terminations while the active instrumentation circuit is live unless the surrounding zone is verified to be non-hazardous.

FAQ

Dove può essere installato questo modulo relè a 16 canali all'interno del rack?

Il modulo è a tutta altezza e può essere collocato in uno qualsiasi degli slot situati a destra del modulo Transient Data Interface (TDI).

Come vengono selezionate le modalità Normalmente eccitato o Normalmente diseccitato?

Le modalità di funzionamento dei relè sono selezionabili tramite interruttori sull'hardware, in quattro gruppi distinti di quattro canali ciascuno.

Qual è la corrente nominale massima per i relè standard nelle applicazioni in CA?

I relè standard supportano una corrente commutata massima di 5 A e una potenza commutata massima di 1200 VA, fino a una tensione massima di 250 V CA con carichi resistivi.

Cosa succede se si applicano carichi elettrici standard ai relè a bassa corrente con placcatura in oro?

Per i relè a bassa corrente con placcatura in oro, la corrente di commutazione massima prima di causare danni ai componenti è rigorosamente limitata a 5 mA per la corrente alternata fino a 120 V CA.
