135489-01 Bently Nevada 3500/42M-04-00 I/O Module with internal Barriers

Description:

Functional Safety (FS) offerings provide enhancement to safety with ability to automatically initiate shutdown of critical production machinery by detecting system characteristics that precede hazardous failure. More specifically, these offerings help operating facilities achieve compliance with IEC 61508. TÜV Rheinland has evaluated Bently Nevada* functional safety products and certified their use to given Safety Integrity Levels (SIL). Applications that are currently supported by our products include Overspeed Detection, Radial Vibration, Thrust Position, Case Vibration, Temperature and Process Variable Input.

An FS version of 3500/53 three-module Overspeed Detection System provides instrumentation for Overspeed shutdown at SIL 3. This offering is triple modular redundant (TMR) that votes in a 2-out-of-3-shutdown scheme or may be selected to provide independent voting. Each I/O module provides four built-in relays, where one is dedicated to Overspeed conditions. The remaining three relays can be configured to respond to any available Overspeed module values and events, including ‘Not OK’. Operation of the relays specifies for no more than 30ms of delay from Overspeed event to relay activation.

FS versions of the 3500/42M or 3500/40M in a Discrete TMR group address SIL 3 safety functions using Radial Vibration and Thrust Position. These vote in a 2-outof- 3 scheme. Each system consists of a set of 3500/42M or 3500/40M monitors, accompanied by a 3500/34 TMR Relay Module. Relay actuation can be configured for direct amplitude proportional values in logical combinations using the 3500/34 TMR Relay Module. Each 3500/34 TMR Relay I/O module provides four built-in relays.

FS versions of 3500/42M and 3500/40M systems for Radial Vibration, Thrust Position, and Case Vibration provide compatibility with SIL 1 safety functions monitoring these characteristics (direct amplitude only). These systems consist of a single monitor card, an FS 3500/32 Four Channel or 3500/33 Sixteen Channel Relay cards, and transducer.

FS versions of 3500/60 and 3500/61 systems provide SIL 1 compatibility for safety functions using temperature monitoring. A single monitor card using six RTD or TC sensors with an FS version of 3500/32 or 3500/33 Relay card makes a sensor-logic part of a temperature based safety function. FS 3500/62 Process Variable monitor used with either FS relay module provides a SIL 1 compatible functional safety monitoring system where sensor input is 4-20mA or -/+10Vdc.
