Product Details 

125720‑01 is the spare part number for Bently Nevada 3500/32 4‑channel relay output module for 3500 machinery monitoring rack. It provides 4 SPDT relay outputs,each channel supports independent AND / OR voting logic,latch and timer configuration via 3500 rack configuration software.

It converts rack monitor alert / danger / OK status into hard‑wired relay alarm signals for external interlock,alarm lamp and safety interlock circuit. It is installed in any slot on the right side of rack interface module inside 3500 chassis. Not applicable for TMR triple redundant systems,3500/34 TMR relay module shall be adopted for TMR projects.

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