Door control relay modules ensure compatibility of access hardware components and simplify system installation and troubleshooting. Modules may be ordered with or without power supplies. Different modules may be specified for one power supply.
Modules may be ordered with or without power supplies. Different function modules may be used in the same power supply or cabinet.
SDC’s FB-4 series allows for precisely calculated circuit protection with four, 2 Amp fuse protected outputs. Distributing the primary DC output of any 600 series power supplies into four, individually fused class 2 outputs to provide up to sixteen outputs and allow for termination of multiple DC devices for ease of maintenance.
Additionally, four on/off switches allow individual control of voltage outputs. LED visual status indicators provide relay activation status.x See Datasheet For More Info
