IF Redundancy Switch : RFS 0070

The RFS 0070 is an IF redundancy switch which detects the presence of primary intermediate frequency RF signal feed and provide the ability to switch to a backup (secondary) signal upon the loss of the primary. These highly reliable RF redundancy switches are ideal for redundancy applications and scheduled maintenance projects. They are perfect for unmanned sites and can help to eliminate the need for emergency restoration service. In addition, an RS-232 DB-9 port has been included through which the RF sensing Switch can be remotely controlled.

 

Features & Benefits

• IF redundancy switches provide automatic backup for signal continuity thereby maintaining your revenue stream.

• Facilitates scheduled maintenance activity with no downtime.

• Eliminates the need for emergency service, permitting maintenance on a managed schedule.

• Rear panel mounted barrier strip provides the interface for a contact closure summary alarm and remote override.

• The threshold is adjustable via front panel for adjustment sensitivity and flexibility.

• Ideal for redundancy switching applications for failed LNB’s, up converters, down converters, antenna rain fade and unmanned facilities.

• Ultra-reliable 1:1 redundancy for backup of fiber links.

• The RFS 2150/2 with serial control provides the ability to remotely control the RF sensing switches via RS232.
