8 channel dry contact to ethernet converter

View : 242
Type : Dry contact closure Over IP
Description :

The converged 8-channel dry contact equipment can transmit up to 8 channel dry contact in the two-layer Ethernet network, and the middle can be connected with the layer-2 network switch

Overview

The converged 8-channel dry contact equipment can transmit up to 8 channel dry contact in the two-layer Ethernet network, and the middle can be connected with the layer-2 network 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

  • ● Integrated circuit based on independent intellectual property rights;
  • ● The equipment shall provide at most 8ch dry contact signal, 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 8ch dry contact switching value or wet pulse contact impulse (Optical MOS Relay), with high reliability and high operation speed;
  • ● Each motherboard can be connected with the node equipment with total switch quantity no more than 8 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;
  • ● 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

Parameters

  • Fiber type

Working wavelength: 1310nm, 1550nm

Speed: 100M, full duplex or half repeater mode

Protocol: support IEEE 802.3, IEEE 802.1Q (VLAN)

MAC address table: can learn 4096 MAC addresses

Physical interface: SFP

The distance of optical fiber transmission is limited by the loss of optical path and the additional loss caused by connecting terminals, connectors and patch boards. The transmission distance may also be limited by the fiber bandwidth

  • 10/100M Ethernet

Rate: 10 / 100M adaptive, full / half duplex fully

adaptive

MAC address table: can learn 4096 MAC

addresses

Physical interface: RJ45 supports auto mdix

  • Dry contact interface

Output interface type:

Dry contact: Optical MOS Relay Output

(maximum internal resistance 25 Ω)
