Dry Contact Closure Over IP

Convergent type 128ch dry contact to Ethernet converter

Overview
The converged 128 channel dry contact equipment can transmit up to 128 channel switch dry contact in the two-layer Ethernet network. It can be divided into two types of equipment: convergence type central equipment and node machine equipment and the middle can be connected with a layer-2 switch.
The product solves the problems of electromagnetic interference ground environment interference and lightning damage and improves the reliability security and confidentiality of data communication. It can be widely used in various industrial control process control and traffic control especially suitable for banks electric power and departments and systems with special requirements for electromagnetic interference environment.
Features
◆ The equipment at the convergence center point shall provide a maximum of 128 dry contact and two 100M Ethernet electrical ports and two 100M Ethernet optical ports can be connected to two optical directions;
◆ The node machine equipment shall provide at most 8-channel  dry contact 2 100M Ethernet electrical ports and 1 100M Ethernet SFP optical port;
◆ Input switch value automatic detection when the input state the switch output is the state which is convenient for project opening;
◆ When the switch value is in the start-up state or when the optical fiber is not connected other switch states are stable and there is no disorderly action state;
◆ It can support two way 64 channel dry contact switching value or wet contact (Optical MOS Relay) with high reliability and high action rate;
◆ Each motherboard can be connected with the node equipment with the total dry contact no more than 128 channels and the equipment at the convergence end through the switch;
◆ Automatic reset function of anti crash monitoring with heartbeat packet sending and detection inside;
◆ It can support independent SNMP network management check the switch on / off status of the office and all front-end devices and the working status of Ethernet and control the front-end equipment;
◆ Switch value interface lightning protection meets iec61000-4-5 (8 / 20 μ s) differential mode: 6kV impedance (2 Ω); common mode: 6kV impedance (2 Ω);
◆ AC 220 V DC - 48V DC + 24 V can be selected. There is no positive and negative pole in DC power supply.
