Information

Overview Manuals Basic Info Ordering Information System Integration Note

Features:

  • 3500/32M 4-Channel Relay Module
  • Each relay of the four channels is switch selectable for Normally Deenergized or Normally Energized
  • The 3500/32M requires 3500 Rack Configuration software, version 4.5 or later
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 Bently Nevada™ 3500 Rack Configuration Software.

The 3500/32 125712-01 Bently Nevada 4 Channel Relay Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
