EOTec Multi-Channel Contact Closure (MCCC)
Request A Quote Overview
Introducing NSPI’s latest Multi-Channel Contact Closure models, now more robust than ever and with the latest certifications, including CE; Class I Division 2 Groups A, B, C, D for the US and Canada; and ATEX Zone-2, Category-3.
The EOTec fiber optic Multi-Channel Contact Closure transceiver modules are used to convert up to ten contact closure inputs into fiber optic signals for transmission over a single fiber optic link. These units are commonly used for remote transmission over long distances (up to 16 miles), transmission through hazardous areas and alarm event triggering.
Applications for this device include long distance transmissions, lightning prone areas, transmissions through hazardous areas.
Cost effective signal multiplexing without a PLC!
Each transceiver module includes two contact closure inputs and is capable of driving up to ten inputs by cascading additional dual channel input modules. A de-pluggable screw terminal on the bottom of the module is provided for connection to the input signal. An integrated backplane allows for communications between modules with no external inter-modular connection.
Flexible design for greater output driving capacity.
Each transceiver has a single optical port for use with multi-mode or single mode optical fiber with transmissions at 850 nm or 1300 nm using industrialized ST/SMA connectors. SPDT Form C relay outputs are provided for each channel capable of driving resistive loads with a maximum switching power of 120W, 250VA, and maximum switching current of 4A DC, AC.
