Core Functional Features
- 16 Independent Isolated Relay Output Channels
Each channel works independently without mutual interference; each channel can be individually configured as alarm output, danger output or emergency trip output through 3500 system configuration software.
- Failsafe Safety Protection Logic
Built-in power failure detection and failsafe circuit; when system power is lost or module fault occurs, relay contacts automatically switch to safe state to avoid unexpected equipment startup and ensure site safety.
- Full Compatibility with 3500 Monitoring Modules
Seamlessly matches all 3500 series monitor modules including vibration monitor, axial displacement monitor, differential expansion monitor, speed monitor and temperature monitor. Automatically receives threshold comparison results from monitor modules.
- Customizable Relay Logic Configuration
Supports logic OR, logic AND, delay setting and channel grouping configuration via official 3500 rack configuration software; meets customized interlock protection strategies of different machinery.
- Plug-in Hot-Swap Design
Supports online plug and replacement without powering down entire system, greatly reduces maintenance downtime and operation interruption.
- High Stability Industrial Hardware Structure
Metal shielded housing, anti-vibration circuit board potting treatment, gold-plated internal bus contacts, long service life under continuous industrial operation.
- Complete Fault Diagnosis Function
Module self-detection function, automatically reports module fault status to 3500 main system and upper computer monitoring platform.
