Bently Nevada Asset Condition Monitoring

ADAPT 3701/55 Emergency Shutdown Device (ESD)

Advanced Distributed Architecture Platform Technology - ADAPT

Baker Hughes Bently Nevada™ Advanced Distributed

Architecture Platform Technology, or ADAPT 3701. is a family of

compact, high performance safety, machinery protection and

condition monitoring solutions targeted at specific assets and

applications.

The ADAPT 3701 family is targeted at machines ranked as

critical to highly-critical where a safety system is necessary

and a permanent on-line protection and condition monitoring

system is recommended.

Key Features

•  Emergency Shutdown Device with integrated Overspeed

Detection System (ODS).

•  IEC 61508 SIL 3 Certification.

•  Triple redundant processor modules (CPU modules).

•  Triple redundant relay output modules with 5 relays per

module. Each relay module has a dedicated Protection Fault

Relay, 2 relays programmable as part of a 2oo3 set or as

independent 1oo1. and 2 independent 1oo1 relays.

•  2 sets of 3 overspeed sensor inputs configurable for magnetic

speed pick-ups or eddy current proximity probes.

•  20 Discrete Inputs.

•  12 inputs configurable as 4-20 mA analog inputs or

discrete inputs.

•  Up to 500 logic blocks.

•  No more than 2 ms logic execution time and 8 ms relay

response time for 10 ms response from input to relay output.

•  2oo3 or 3 independent 1oo1 ODS configuration.

•  Redundant 24VDC Power Inputs.

•  Six 4-20 mA outputs, two from each processor module

proportional to the configured full scale speed range.

•  Two 10Base-T/100Base TX RJ45 Ethernet connections per

processor module.

•  Hardware configuration lock prevents changes when

in run mode.

•  Modbus TCP communication.

•  Regulatory Compliance and Certifications: EU: LVD & EMC

and machinery directive pending SIL, North America General

Safety, RoHS compliant, (North America Zone 2 Haz Loc, and

ATEX Zone 2 planned).
