This media converter series converts a contact-closure signal input into optical signals for transmission over a single fibre-optic link in both directions. It is available with NO or NC dry contacts output.

The ET111CBH series extends up to 20 km for remote transmission over long distances and provides fast relay response time in 2ms, bridging the gap between automation, control environments and traditional IP-based networks. The ET1111CBH Series is designed for extreme temperature environments, operating from -40°C to 75°C (-40°F to 167°F). The series offers flexibility and is suited for the applications with access control, emergency help points, traffic control, gate control, building automation and fire and alarm systems.

With zero configuration necessary and a small-scale design, the ET111CBH series can be installed quickly and easily in most camera housings. The fibre supports single mode and multi-mode and allows for the SC and ST connectors. The dry contact closure is bi-directional and offers a quick response time of <2ms, as well as normally open and closed for the one channel dry contact. The output rating is max.32VDC/VAC@ 100mA.
