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 4 Channel 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.
