Input or output Contact Closure modules for modular fiber optic transmission system.
Combined with modules of central unit and optical communication and integrated into IFOTEC racks, these products can be used to transmit up to 128 channels CC over a single optical fibre.
- Transmission up to 10 km over multimode fibre or up to 50 km over single-mode fibre by the same optical communication central units.
- Optical connector: SC/PC
Depending on its reference, each HMTE / HMTR-16T Contact Closure module has:
- 16 Current loop CC inputs.
- 16 CC outputs by OptoFET transistors.
The associated module of central unit and optical communication allows:
- Collection and transmission of information of TOR lines by the back panel.
- Transmission and multiplexing of information over fibre in both directions.
- Optical reception and information demultiplexing.
- Rack supervision by web page with RJ45 Ethernet access.
- Management of two configurable alarm contacts.
This equiment is well adapted for access control, alarm control, to automata,…
