Analog and/or digital I/O to fiber optic converters

Analog signals (0–10 V or 0–20 mA) and/or digital signals can be transmitted bi-directionally via POF (Plastic OPtical Fiber), HCS (Hard Clad Silica), singlemode (SM) or multimode (MM) fiber optics. Thus, it is possible to control and connect drives or lighting reliably and to get a status response. There are more than 60 versions who are different regarding signal, fiber or connector type. The modules can be used in point to point structures for transmission paths of up to 100 km with singlemode fiber optic. The contact closure signals and the responses can either be transmitted via two fibers or – when using BiDi-technology – even via one single fiber.
