-
Automated safety logic for turbines, compressors, pumps, and gearboxes
-
Redundant hazard signaling in API 670‑compliant monitoring architectures
-
Remote indication and control interfacing in distributed condition monitoring deployments
This relay board enables safe coordination between internal monitor logic and external plant safety systems.
Advantages
-
Reliable Machine Protection Interface: Provides dependable contact closure outputs for alarm and shutdown logic in condition monitoring systems.
-
Compact and Modular: Fits directly into 3300 system racks without external relay housings or additional wiring.
-
Strong Signal Isolation: High isolation voltage and arc suppressors extend contact life and improve system stability.
-
Versatile Output Configuration: Supports dual or quad relay arrangements to match signaling needs.
-
Industrial‑Ready: Designed for continuous duty and resistance to vibration and temperature stresses common in machinery environments.
Together, these features make the 78462‑01 an effective relay interface for condition‑based protection systems.
Technical FAQs (Frequently Asked Questions)
-
What function does the 78462‑01 module perform?
It provides discrete relay outputs in response to internal monitor alarm and hazard conditions in a 3300 series system.
-
What voltage does this relay module require?
The unit runs on a nominal 24 V DC logic supply provided by the monitoring system.
-
What types of contacts does it offer?
Relay contacts are configured as double‑throw or single‑throw outputs depending on module options.
-
Can it trigger external shutdown devices?
Yes — relay outputs are suitable for interfacing with automatic shutdown logic or annunciators.
-
Is this module soldered or plug‑in replaceable?
It installs in the 3300 rack or DIN rail slot, making it replaceable without chassis modifications.
-
What is its typical contact rating?
Contacts are commonly rated around 1 A at 30 V DC.
-
Does this module include arc suppression?
Yes — arc suppressors are standard to prolong contact life.
-
Can I use it outside the 3300 system?
It is engineered specifically for the 3300 monitoring platform, though electrical signal standards may allow integration with compatible systems.
-
Is this module suitable for hazardous areas?
Relay sealing options (epoxy or hermetic) vary; hermetic versions support harsher environments.
-
How does it contribute to condition monitoring safety?
It translates internal alarm logic into physical relay actions used for shutdown and external alarm circuits.
