1-8 Optical Directions Optic Fiber Convergence Type 16-channel Dry Contact Modem

● Anodized aluminum alloy shell, IP40 protection level, can withstand the test of harsh environment;

● With 8 SC/FC/LC fiber modules, it can connect 8 optical directions, divided into two types of equipment: aggregation center equipment and node equipment

● The aggregation end can output a total of 16 dry contactinterfaces, or Modbus RTU or Modbus TCP. When outputting physical dry contact, the node equipment provides up to 1-2 dry contact. When outputting Modbus RTU or Modbus TCP, the node equipment provides up to 1-16 dry contact, which can be input or output, connected by optical fiber in the middle;

● The input dry contactis automatically detected. When the input state is what state, the dry contact output is what state, which is convenient for project commissioning;

● When the dry contactis in the power-on state or the optical fiber is not connected, the other switch states are stable, and there will be no random action state;

● It can support dry contact dry contact, or wet contact (optical MOS relay), high reliability and high action rate;

● Each motherboard can be connected to the node equipment with a total dry contactof no more than 16 channels through a switch and the aggregation end equipment;

● The equipment comes with Modbus RTU or Modbus TCP interface, can send and receive data through Modbus protocol (optional);

● The lightning protection of the switch interface reaches IEC61000-4-5 (8/20μS) differential mode: 6KV, impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;

● Meet the requirements of industrial level 4 electromagnetic compatibility;

● Super strong lightning protection function: lightning protection, anti-inductive high voltage, anti-surge, etc.;

● No fan, efficient heat dissipation, reducing repair time;

● Optional AC 220V, DC -48V, DC +24V, DC power supply has no positive and negative polarity, supports internal isolation, redundant dual power input
