3500/33 16-Channel Relay Module

3500/33 16-Channel Relay Module

Description 

The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module. Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic. Each relay of the module includes Alarm Drive Logic. Programming for the Alarm Drive Logic uses AND and OR logic and may use the following: l Alarming inputs (alert and danger statuses) l Not-OK l Individual Measured Variables from any monitor channel or any combination of monitor channels in the rack You can program the Alarm Drive using the 3500 Rack Configuration Software.

Ordering Considerations l The 3500/33 16-Channel Relay Module requires the 3500 Rack Config, version 3.3 or later. l The 3500/33 requires the 3500 Data Acquisition Software, version 2.40 or later. l The 3500/33 16-Channel Relay Module requires the 3500 Data Display Software, version 1.40 or later. l When ordered with the multiple approvals option (02), the 3500 monitor is certified to Zone 2 standards, including ATEX and North American zones. l The Zone 2 standards specify increased spacing requirements at higher voltages. The 3500/33 16-Channel Relay Module does not meet these spacing requirements. Thus, the module ordered with the multiple approvals option is limited to a lower voltage than those with the other approvals options. l Using higher voltages violates the hazardous area certificates associated with the multiple approvals option. l The North American Division 2 standards associated with the CSA-only approvals option (-01) have been de-rated to 30 Vrms to comply with 61010-1 type test requirements. l If the 3500/3316-Channel Relay Module 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.
