350070M-SIL2

Product Description

It provides continuous online monitoring of machinery vibration and process variables, meeting the rigorous requirements of IEC 61508 for functional safety. The monitor accepts signals from proximity transducers, accelerometers, and velocity sensors, and can be configured to perform radial vibration, thrust position, and eccentricity measurements. With its SIL2 certification, it is suitable for applications where a high level of safety integrity is required, such as in the oil & gas, power generation, and chemical industries. The 3500/70M-SIL2 is a half-height module that fits into any slot of a 3500 rack. It features four channels, each independently programmable for various measurement types and alarm setpoints. The module communicates with the 3500 rack's internal bus and can be configured using the 3500 Rack Configuration Software. It supports both current and voltage outputs, and provides relay alarm outputs via the associated 3500/32 or 3500/33 relay modules. The SIL2 version includes enhanced self-test and diagnostic capabilities to ensure safe operation and to meet the requirements of safety integrity level 2. This monitor is a key component in the 3500 Series Machinery Protection System (MPS), which is widely used for protecting rotating and reciprocating machinery. The 3500/70M-SIL2 is designed to be form-fit-function compatible with the standard 3500/70, but with additional safety features and certifications. It is a new original product, available with a warranty, and is ideal for both new installations and upgrades of existing 3500 systems that require SIL2 compliance. The Bently Nevada 3500/70M-SIL2 is a SIL2-certified version of the 3500/70 monitor, designed for use in safety-instrumented systems (SIS) within the 3500 series rack.

Technical Specifications

Version & Model Difference

The 3500/70M-SIL2 is the SIL2-certified variant of the standard 3500/70 monitor. The primary difference is the addition of safety-related features and certification to IEC 61508 SIL2. This includes enhanced self-testing, redundancy options, and a more rigorous development process. The SIL2 version is functionally equivalent to the standard 3500/70 in terms of measurement capabilities, but it is specifically designed for use in safety-instrumented functions where a SIL2 rating is required. The standard 3500/70 does not have SIL certification and is intended for non-safety critical monitoring. The 3500/70M-SIL2 is also available in a version with an integrated keypad for local display (3500/70M-SIL2 with display), while the standard 3500/70 may have different ordering options.
