4 Channel Contact Closure SFP
DIN Fiber Link System
Installation and Configuration
Information
Description
The system provides transmission of four (4) independent
input signals over fiber optic cable. Applications include alarm
event triggering, building automation, environmental control
systems, fire & alarm systems, gate control, traffic signal
control equipment, and more.
Fiber optic cable is immune to RF noise, EMI, high voltages,
and may extend the signal up to 100km. A complete system
requires a Transmitter and Receiver, a 24-48VDC power
source, and a compatible SFP transceiver for the fiber
interface.
Each unit features a wide operating temperature, redundant
power terminals, and a system alarm contact for monitoring
the unit for proper operation. LED indicators provide a
convenient view of the systems current status. This hardened
system can be wall or DIN rail mounted with the included DIN
clip and wall mount ears, is made in the USA, and backed by
our limited lifetime warranty.
Contact Input - Transmitter Device
The input terminals have the ability to sense 4 independent
inputs. The dry contact model makes installation of the unit
quick and simple. Wet contact models have the ability to
receive an input signal between 5~12VDC or 24~48VDC.
Contact Output - Receiver Device
Each receiver device is paired with a transmitter on the
opposite end of the system. The relays will be factory set to
Normally Open or Normally Closed and for both these options
