Dry Contact closure over Fiber Optical Multiplexer 16 channel Industrial Rail Mounted Mux

This Dry Contact closure over Fiber Optical Multiplexer delivers secure and interference-free dry contact signal transmission over fiber optic cable. Designed for industrial control and alarm communication systems, it supports 16-channel unidirectional or 8-channel bidirectional dry contact transmission.

The rail mounted optical multiplexer uses fiber optics to protect signals from electromagnetic interference, electrical surges, and lightning damage, ensuring stable long-distance communication in demanding industrial environments. With automatic NO/NC state detection, fast response speed, and industrial-grade protection, it is ideal for automation systems, traffic monitoring, substations, and security applications.

Supporting up to 100km single-mode fiber transmission and multiple power supply options, this Dry Contact closure over Fiber Optical Multiplexer offers flexible deployment for industrial communication networks.

Dry Contact closure over Fiber Features

• Based on proprietary integrated circuit;
• can be configured as an 16 inputs / 16 outputs / 8 inputs + 8 output mode
• Enter the normally open normally closed dry contact automatically detects when the input what state switch output that is why the state, to facilitate the project opened
• dry contact turned on when not connected to other dry contact or fiber state is stable, does not appear chaotic action status
• can support unidirectional dry contact or bidirectional dry contact.
• Each has a dry contact on and off the lights
• dry contact interface Lightning reach IEC61000-4-5 (8 / 20μS) differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard
• optional AC 220V, DC -48V, DC + 24V, DC power no positive and negative points;
