Carries four dry contact signals over a single fiber

It converts dry contact and TTL signals into an optical link and sends four channels one way over a single fiber. Since fiber replaces the copper run, EMI, RFI and ground loops do not corrupt the signal.

Key features

Contact interfaceA 2x terminal block (5 pin, 3.5 mm) accepts TTL, dry contact and ON-OFF signals; the contacts are normally open.

Optical budgetThe transmitter sends -15 to -8 dBm and the receiver reads signals down to -35 dBm.

DistanceReaches 2 km over multimode fiber and 20 km over single mode fiber.

Interference immunityEMI, RFI and ground loops do not corrupt the signal, and LED indicators show live traffic.

MountingRuns as a stand-alone box or rack mounted, and supports the hot-swap function.

Housing and powerThe 102 x 108 x 27 mm housing runs on DC 5 V power.

The contact closure channels operate in one direction only, from Tx to Rx.
