Module Overview
The Bently Nevada 125720-02 4-Channel Relay Output Module expands the 3500 monitoring system. Moreover, it allows multiple programmable outputs, enabling flexible alarm and voting logic configurations. In addition, technicians can install these relay modules in any slot adjacent to the Transient Data Interface Module, simplifying system expansion.
Functional Highlights
- Individual Programming: Each relay channel performs independent AND/OR alarm logic according to user settings.
- Alarm Integration: The module accepts alert, danger, Not-OK, and PPL signals from any monitor channel.
- Reliable Operation: Epoxy sealing protects relays, ensuring robust operation in harsh industrial environments.
- Arc Suppression: Standard 250 Vrms arc suppressors protect contacts during high-current switching.
