Product Details

3500/32 is 4‑channel full‑height relay output module for Bently Nevada 3500 machinery protection rack. Multiple 3500/32 modules can be installed on slots right of rack interface module.

Each SPDT relay channel supports independent alarm‑drive voting logic via 3500 rack configuration software. It can reference Alert, Danger, Not‑OK status from any monitor channel inside the rack to realize complex AND / OR logic interlock. Every channel can be set to normally‑energized or normally‑de‑energized mode with latching alarm option.

It converts rack monitoring alarm signals into hard‑wired relay contacts for external alarm lamps,interlock circuits and safety protection. Not applicable for TMR triple‑modular‑redundant projects; TMR application shall adopt 3500/34 TMR relay module.

Note:This is legacy 3500 series spare component,widely used for replacement of turbine and compressor TSI monitoring & protection systems。
