![]() Ambient temperature: Storage: -40.+70☌, Operating in non-rowed installation: 0.+60☌, Operating in rowed installation 0. Housing: Plastic housing for top hat rail installation, 105 x 22 x 75mm (L x W x H) Supply connection: Plug-in screw terminal, 5.08mm spacing, Labeled "L+" and "M" Termination: Connectable termination network for RS485 operation 10µs for switching from data send to receive for RS485 automatic control (can be changed on request) Provides Power Supply Isolation (optical isolation voltage 2500Vrms 500DC continuity) RS-232 interface - 15kV ESD protection RS485/422 end with each line of 600W lightning surge protection Port-powered or by DC 9V-24V power adapter LED indicators for troubleshooting - easy check in the status of power connection and balanced differential. Operating modes: RS422, RS485 4-wire with automatic control, RS485 2-wire with automatic control Serial ports: RS422/RS485 interfaces, selectable, 9-pin SUB-D adapter RS422/RS485 Isolator with integrated overvoltage protection, Model 66203 High transmission speeds of up to 3 MbaudĬareful circuit design and generous component dimensioning ensure more than 25 years of service life Buy COMMFRONT Industrial RS485 / RS422 Isolator/Repeater/Converter, 2500V Optical Isolation, 600W Surge and 15kV ESD Static Protection: Chargers & Adapters. ![]() No re-configuration of transmission parameters required It must be ensured that the bus is electrically isolated when connected to the PC, or that the PC is isolated by suitable measures such as UPS.Įlectrical isolated connection of RS422 devices and RS485 bus systems. ![]() If the controllers are grounded over the control bus and the PC, the entire control circuit might be disrupted by equalizing currents. The Isolator model 66201 enables galvanically isolated connection between RS422 devices and RS485 bus systems.Ĭontrol circuits are often electrically isolated. The OPTO-4 is our latest Opto-isolated adapter cable.RS422/RS485 Isolator, 1kV isolation voltage PLEASE NOTE THE OPTO-1, OPTO-2, AND OPTO-3 ARE RETIRED PRODUCTS. If you require more flexibility for a RS232 / computer source to add its own NMEA data to the NMEA network, the Actisense NMEA Multiplexer ( NDC-4) will fulfill most if not all requirements. Once the cable is wired to the NMEA 0183 network, and the connector plugged into the computer, the data will be available via its serial communications port. The baud rate supported at the same time is up to 115. This adapter cable needs no external power supply as the interface takes all its power from the computer port. ADVANTAGE: YN2209 optical isolator can extend the existing RS485 by 1200m to solve the problem of signal attenuation caused by too long RS485 wiring. can induce or conduct very large voltage and current spikes into the vessels power cables computer ports (RS232, USB etc.) are designed to handle low voltage and low current signals only and are easily to damage in the marine environment. ![]() Potentially damaging voltage or current spikes can be present in the electrically noisy environment of the vessels wiring network – alternators, motors etc. This cable allows easy, safe and low-cost connection of an NMEA 0183 system (or any other compatible RS422 / RS485 system) to a laptop or PC, by matching a standard RS232 D-type 9-pin serial port to an NMEA 0183 type marine bus link. Simply put, to protect your computer investment – if the serial communications port on a laptop is damaged, it is normally a very expensive repair that could require replacement of the entire motherboard. ![]()
