● Integrated circuits based on independent intellectual property rights;
● It can support unidirectional 14-channel dry contact and bidirectional 7-channel dry contact, and provide one alarm output. When the optical fiber is broken or the power is off, one dry contact (the 16th) dry contact output is closed;
● Each channel has an indicator light indicating the dry contact is on and off;
● Automatic detection of the input dry contact on and off, when the state of the input, the state of the dry contact output, which is convenient for project opening;
● When the dry contact is turned on or the optical fiber is not connected, its dry contact state is stable, and there will be no disorderly action state;
● The normally open and normally closed state of the output dry contactcan be set through the DIP switch when the fiber is not connected;
● Dry contact interface anti-radar to IEC61000-4-5 (8/20μS) differential mode: 6KV, impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;
● Support a wide range of AC and DC input, support internal isolation, redundant dual power input, power supply supports overload protection, and anti-reverse connection protection;
● Comply with industrial level 4 electromagnetic compatibility requirements;
● Super lightning protection function: lightning protection, anti-inductive high voltage, anti-surge, etc.
● Fanless efficient heat dissipation, reducing repair time;
● DC 9-55V DC power supply or AC9-50V AC power supply, no positive and negative poles.
