BENTLY NEVADA 149986-01 Spare 16-Channel Relay Control Module

Description

The BENTLY NEVADA 149986-01 is a 16-channel relay control module, an integral component of the 3500 Series monitoring system. Classified as a full-height module, it can be installed in any slot to the right of the frame interface module within the 3500 Series rack. As a low-current 16-channel failsafe relay output module, it is designed for industrial equipment protection and interlock control applications.

Core functions include receiving signals from monitor modules, then triggering internal relay contacts based on preset logic and thresholds to execute external device actions such as alarm activation and shutdown control. It supports flexible software programming via the 3500 rack configuration software, allowing users to customize relay action thresholds and logical relationships to match specific operational requirements. Each of its 16 output channels can be independently programmed to execute required voting logic. The module’s alarm drive logic uses “AND gate” and “OR gate” programming, enabling it to utilize alarm inputs (warning or danger), non-OK signals, or independent PPL from any monitor channel or combination of channels within the frame to support tailored industrial equipment protection workflows.
