3500/32M 4-Channel Relay Module
Datasheet
Bently Nevada Machinery Condition Monitoring
Description
The 4-Channel Relay Module is a full-height module that
provides four relay outputs. Any number of 4-Channel Relay
Modules can be placed in any of the slots to the right of the
Transient Data Interface Module. Each output of the 4Channel Relay Module can be independently programmed to
perform voting logic.
Each relay utilized on the 4-Channel Relay Module includes
Alarm Drive Logic.
Programming for the Alarm Drive Logic uses AND and OR logic,
and can use alarming inputs (Alert and Danger statuses),
Not- OK, or individual PPLs from any monitor channel or any
combination of monitor channels in the rack. You can
program this Alarm Drive to meet your application needs
using the 3500 Rack Configuration Software.

WARNING
Due to the potential for varying
voltage levels, please review the
following:
• 3500 monitors ordered with
hazardous approvals options (01 & -
02) are certified to Division 2/Zone 2
standards (including ATEX/IECEx
and North American Zones and
Divisions). The Division 2 /Zone 2
standards specify increased
spacing requirements at higher
voltages, and the 3500/32M relays
do not meet these spacing
requirements. For this reason,
3500/32M relays ordered with the
hazardous area approvals options
(including country-specific
hazardous area approvals options)
have historically been limited to a
lower voltage than those ordered
with non-hazardous approvals
options. Using higher voltages
would violate the hazardous area
certificates associated with the
hazardous area approvals option.
• If the 3500/32M is part of a
functional safety (SIL) system, the
functional safety certificate
requires the restricted voltage.
Higher voltages are not allowed for
functional safety (SIL) systems.
• It is possible to connect field wiring
to the 3500/32M relays such that
conductors are exposed to
potential human contact. This could
present a shock hazard at high
voltages. Customers shall only use
the 3500/32M relays at the voltages
specified. Appropriate safety
precautions must be taken with
respect to the shock hazard.
