Olycom Industrial Contact Closure Over Fiber Optic Link Converter
Introduction
Designed for mission-critical monitoring and control systems, the Olycom IM610-8KWTR is a rugged, Din-rail mountable opto-electronic converter that transports up to eight independent contact closure (alarm/binary) signals over a single optical fiber.
Leveraging WDM (Wavelength Division Multiplexing) technology, it achieves full‑duplex bidirectional communication on just one strand, drastically reducing cable infrastructure costs and simplifying long‑haul deployments.
Its wide input voltage range (12–52V DC) and industrial‑grade component selection ensure reliable operation in harsh environments, from freezing cold to scorching heat, making it an ideal backbone for distributed sensing and actuation networks.

Bullet Points
True galvanic isolation – eliminates EMI, RFI, and troublesome ground loops, ensuring clean signal transmission even in electrically noisy substations or factory floors.
Extreme optical budget – supports link losses up to 30 dB, allowing flexible installation over distances from 2 km (multimode) up to 80 km (single‑mode) without repeaters.
Versatile I/O compatibility – accepts and outputs TTL, RS‑232/422/485, or dry‑contact switch signals, and can drive relay outputs for direct actuator control.
Built‑to‑last durability – operates from ‑40°C to +75°C and withstands 0–95% non‑condensing humidity, with integrated lightning/surge protection for outdoor or exposed installations.
Compact & tool‑friendly – space‑saving 113.8×93×35 mm housing, lightweight 0.30 kg, and SFP‑based optical interface enable quick field swaps and future‑proof upgrades.
Application
The IM610‑8KWTR excels in scenarios where reliable, long‑distance status monitoring and remote control are paramount.
Typical use cases include:
Transportation infrastructure – toll station alarm panels, expressway perimeter intrusion detection, and tunnel emergency call systems.
Urban surveillance networks – city‑wide traffic light status feedback and security sensor backhaul for safe‑city initiatives.
Industrial & utility assets – remote tank level alarms, pipeline valve position monitoring, and substation breaker status reporting in oil, gas, and electric power sectors.
Public venues & critical facilities – fire/intrusion sensors in stadiums, airports, railway stations
Broadcast & events – real‑time equipment fault signaling for live TV/audio transmission chains, ensuring uninterrupted program delivery.
