Description:

The 3500/32M Relay Modules provide a set of relays that can be programmed to actuate based on alarm conditions in other monitor modules in the rack. The /32M module (left photo) uses double pole double throw (DPDT) relays, while the /33 module (right photo) uses single pole double throw (SPDT) relays. The /32M module has 4 DPDT relay channels and the /33 unit has 16 SPDT relay channels. The /33 can also be configured to act as if it has DPDT relays. Doing this will use two SPDT relays to perform the function of every DPDT relay that is configured.

Although relay modules are not a required component of the 3500 System, we strongly recommend using them as the most appropriate way to integrate the 3500 System with automatic shutdown applications. Any number of relay modules can be placed in any of the slots to the right of the TDI.

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.
