BENTLY 149992-01 Spare 16-channel relay output module

Channel Density

4-channel Monitors allow a single full size (14 slot) 3500 rack to accommodate up to 56 monitoring channels.

This efficient use of space results in lower installation costs by saving valuable cabinet space. 

It also facilitates sharing common components, such as displays, communications gateways, and power

supplies, across more channels for less cost per channel.

Reliability and Integrity

The 3500 System can be configured with varying levels of redundancy. This ranges from simplex modules to

dual power supplies to redundant relay modules with wide ranging and flexible logical operator options for

configuring complex relay logic as needed.

The 3500 System also offers a variety of Safety Integrity Level (SIL) certifications (SIL 1 and SIL 2) for various 3500

monitors used in safety instrumented systems subject to Functional Safety Certification.

The 3500 System incorporates numerous selfmonitoring functions that can identify faults in the monitor modules and their connected transducers,

annunciate and identify problems via appropriate errorcodes, and suppress channel operation automatically

when a failure could compromise correct operation of the system.

The 3500 System stores configuration settings in two separate locations in each module’s non-volatile

memory. This redundancy allows each module to compare configuration information for agreement and to flag any anomalies.

The use of redundant, non-volatile memory also accommodates programming a spare module ahead of

time. It also ensures that, in the event a redundant power supply is not used, monitor configuration is not

lost when power is interrupted and monitoring functions can resume immediately upon reapplication of rack

power. Refer to the Bently Manuals DVD for 3500 SIL Safety Manuals.

Features Overview

The 3500 System is intended for continuous,permanent monitoring of rotating and reciprocating machinery in a variety of industries. 

It is specifically designed for use in auto-shutdown machineryprotection applications that require extremely high reliability and availability.

Remote Accessibility

Networked connections allow you to remotely configure a 3500 system and even assess the system when an

instrument problem arises. You can implement simple changes, such as to an alarm setpoint or a filter corner,

without traveling to the site in person. This is useful for installations at offshore platforms, compressor or pump

stations, emergency generators, and other locations where on-site access to the instrumentation is inconvenient or impractical.

Cybersecurity

The 3500 System’s two levels of password protection combined with a keylock for configuration changes

ensures the system can’t be adjusted, changed, or configured except by authorized personnel.

The 3500 rack records any configuration changes in the system’s event list, which accommodates effective

“management of change” documentation.

We also offer Wurldtech™ Achilles® Level 1 certified solutions as well as full engineered and hardened

network architectures when required to meet specific cybersecurity needs.
