Product Overview
-
Brand: Bently Nevada
-
Series: 3500 Series Machinery Protection & Condition Monitoring
-
Model: 3500/32 125720‑02
-
Type: Four-Channel Relay Output Module (Full-Height)
Product Description
The 3500/32 125720‑02 is a full-height relay I/O module offering four SPDT relay channels. Each relay supports independent programming with AND/OR “Alarm Drive Logic” and fits into the standard rack to the right of the transient data interface. The module includes built-in arc suppression and diagnostic LEDs and is designed to operate under harsh industrial conditions.
Applications
