3500/32M 4-Channel Relay Module
Datasheet

Bently Nevada Machinery Condition Monitoring141533 Rev. VDescription
The 4-Channel Relay Module is a full-height module thatprovides four relay outputs. Any number of 4-Channel Relay
Modules can be placed in any of the slots to the right of theTransient Data Interface Module. Each output of the 4Channel Relay Module can be independently programmed toperform 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 Dangerstatuses), 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 applicationneeds using the 3500 Rack Configuration Software.

WARNING
Due to the potential for varying
voltage levels, please review thefollowing:Standard Relays
Minimum switchedcurrent• 3500 monitors ordered withhazardous approvals options (01 &-02) are certified to Division 2/Zone
2 standards (including ATEX/IECEx
and North American Zones andDivisions). The Division 2 /Zone 2standards specify increased
spacing requirements at highervoltages, and the 3500/32M relays
do not meet these spacing
requirements. For this reason,
3500/32M relays ordered with thehazardous area approvals options(including country-specifichazardous area approvals options)have historically been limited to alower voltage than those orderedwith non-hazardous approvals
options. Using higher voltages
would violate the hazardous area
certificates associated with thehazardous area approvals option.

requires the restricted voltage.
Higher voltages are not allowed forfunctional safety (SIL) systems.
• It is possible to connect field wiring
to the 3500/32M relays such that
conductors are exposed topotential human contact. This
could present a shock hazard athigh voltages. Customers shall only
use the 3500/32M relays at thevoltages specified. Appropriate
safety precautions must be takenwith respect to the shock hazard.
