4Ch Alarm Relay Output Fibre Receiver Unit

MSRP Starting Price: R 1,626.00


The FT-DIO-OP4-SA is a fibre optic alarm relay output receiver unit. Stand-alone, it allows the reception of alarm input signals from a FT-DIO-IP4-SA alarm transmission unit.


  • Outputs:x5 (4 from Fibre TX and 5th is for Fibre Loss/Power Fail Alarm)
  • Relays:6A 250VAC/28VDC
  • Output:x 1 (ST Connector) Fibre  
  • Fibre Type:850nM Multi-Mode Fibre
  • Dimensions:(W)90mm x (L)110mm x (H)50mm
  • Power:12VDC Operation
  • Compatible Transmitter: FT-DIO-IP4-SA

Applications for the unit include distributed security alarm monitoring, industrial automation as well as data acquisition. Four Digital Inputs or Contact Closures are received from the transmitter unit, over a signal fibre optic cable and then converted into relay outputs.

A 5th relay is fitted to the unit which is switched when the fibre signal is lossed from the transmitter.  This function is useful for mission critical applications which require notification in the control/server room of a loss of fibre signal from the remote location.

The unit's enclosure is constructed from aluminium and has screw terminals for I/O connections. Operation is off 12VDC. Card rack versions of the receivers are also available. These allow multiple cards to be rack mounted in our RM-4S-1200 card enclosure.
