Product overview:

  • Low-current 16-channel relay output with gold-plated contacts
  • Independently programmable Alarm Drive Logic for every output
  • Supplied SIL2 qualifier requires complete certificate verification

The 3500/33 relay module translates configured rack alarm logic into 16 isolated SPDT output channels.

For safety service, validate the exact certified configuration and apply the restricted contact ratings and proof-test instructions.

Verified resources for Bently Nevada 3500/33-SIL2-03-01:

Additional technical data:

  • Typical power consumption: 5.8 watts
  • Minimum low-current load: 1 mA at 1 Vdc
  • Maximum low-current rating: 100 mA at 48 Vdc
  • Relay operation selection: four groups of four channels, normally energized or de-energized
  • Main module dimensions: 241 x 24.4 x 242 mm

Ordering structure:

  • The official template contains only AA output and BB approval fields
  • AA 03 selects low-current relay outputs
  • BB 01 selects cNRTLus Class I Division 2
  • The inserted SIL2 text must be checked against the safety certificate and rack configuration

Compatibility checklist:

  • Use the matching 16-channel low-current rear I/O module
  • Confirm supported rack configuration software
  • Validate the certified safety loop and restricted voltage
  • Map every relay channel to the intended alarm logic and field load

Installation checks:

  • Verify contact voltage and current before wiring
  • Select normally energized or de-energized operation in groups of four
  • Load the approved Alarm Drive Logic configuration
  • Perform the required channel and safety proof tests before service
Description

3500/33-SIL2-03-01 is a supplied reference associated with the Bently Nevada 3500/33 16-Channel Relay Module. Current ordering literature identifies option 03 as a low-current output module with gold-plated contacts and option 01 as cNRTLus Class I, Division 2 approval.

The standard ordering template is 3500/33-AA-BB, so SIL2 is not a normal order-code field. Confirm the functional-safety certificate, restricted contact ratings, relay/I/O combination, rack configuration and proof-test requirements before quotation or use in a safety function.

Technical notes
3500/33-SIL2-03-01 must not be treated as proof of SIL2 capability by part number alone. Functional-safety use depends on the certified system configuration and restricted relay-contact voltage.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is 3500/33-SIL2-03-01 the standard ordering format?
No. The current product template is 3500/33-AA-BB; SIL2 is a supplied configuration qualifier that requires certificate verification.
What does option 03 identify?
It selects the low-current 16-channel relay output module with gold-plated contacts.
What does approval option 01 mean?
It identifies cNRTLus Class I, Division 2 hazardous-area approval.
Does the reference alone establish SIL2 compliance?
No. The complete certified rack, monitor, relay and proof-test configuration must match the applicable functional-safety certificate.
How are the relay outputs programmed?
Each SPDT output has configurable Alarm Drive Logic using AND or OR combinations of rack alarm and measured-variable states.
What contact limits apply in safety service?
Use the restricted ratings required by the functional-safety and hazardous-area documentation; higher voltages are not permitted in those configurations.
Where is the relay technical document?
The Manuals tab provides an Apter-hosted 3500/33 document with contact ratings and ordering information.
What must accompany a quotation request?
Provide the safety-certificate reference, rack revision, relay/I/O pair, contact load, proof-test interval, quantity and destination.
