Technical Specifications and Hardware Overview
The Bently Nevada 3500/33-SIL2-03-01 functions as a 16-channel relay output module for the 3500 series monitoring system. This module measures 241 mm in height, 50 mm in width, and 210 mm in depth for standard rack mounting. It weighs approximately 1.2 kilograms, which provides stable mechanical integration within the chassis. The unit draws 0.5 A from a 24 V DC supply, consuming roughly 12 W under full operational load. It features 16 independent relay outputs for alarm and trip signal distribution. The module includes a front-panel connector for external wiring termination.
Each relay offers form C (SPDT) contacts with both normally open and normally closed options. The contacts handle switching voltages up to 220 V AC or 30 V DC. They support continuous currents up to 2 A with a maximum switching capacity of 60 W. The unit incorporates SIL2 functional safety certification for critical protection applications. It provides a response time of less than 10 ms for rapid alarm activation. The module includes manual override switches for maintenance and testing procedures. The operating temperature range spans -20°C to 65°C for harsh industrial environments. Storage temperatures extend from -40°C to 85°C without causing component damage. Humidity tolerance covers 5% to 95% non-condensing conditions.

Relay Output and Safety Features
This relay module provides 16 channels for alert and protection signal distribution. Each channel operates independently with Form C contacts for versatile output connections. The Bently Nevada 3500/33-SIL2-03-01 offers SIL2 certification for safety-critical system applications. It implements a response time of less than 10 ms for timely fault indication. The unit includes individual manual override switches for maintenance and testing operations. It uses latching relays to maintain contact states during power interruptions.
Installation and System Integration
The 3500/33-SIL2-03-01 mounts into a 3500 series rack chassis. It occupies one slot for straightforward system integration. The module connects to the backplane via a 48-pin connector. It interfaces with monitoring modules for alarm output routing. The unit delivers a mean time between failures of 150,000 hours. It carries CE and ATEX certifications for global deployment. The module passes vibration testing at 10 to 55 Hz with 0.15 mm amplitude. It withstands shock loads up to 5 g for 30 ms duration without degradation.
