![]() when fiber optics disconnects or dual power supply fails, ALM indicator would be bright and send alert, at the same time the alarm device connecting to the relay would sent alert for quick trouble shooting on the scene. The DIP switch could implement functions like Master/Slave option, RS-485 terminal resistance enablement, relay alarm of power failure and fiber optics disconnection (notes: power supply alarm is only for dual power supply product), etc. They adopt DIN-Rail mounting, which can meet the requirements of different scenes. This series provide 1 or 2 fiber ports with ring network function, 1 RS-232/485/422 serial port and multiple optional power solutions like 85~265VAC, 110~370VDC or 12-48VDC (single/dual power supply). They convert RS-232/485/422 serial port signal to optical signal and provide users with RS-232/485/422 serial port to implement transparent end-to-end transmission. IMF2100 series are 1/2 fiber ports + 1 RS-232/485/422 serial to fiber MODEM. Support -40 75 wide operating temperature range. Support multiple optional power solutions including 85~265VAC, 110~370VDC or 12-48VDC (single/dual power supply) Support 1 relay alarm output for power failure and disconnection of fiber optics Support 1/2 fiber ports and 1 RS-232/485/422 serial port with isolation Notice: Undefined index: ecomUrl in /home/indiamart/public_html/prod-mdc/IMPaidClnt/TmplViews/d0066/category.php on line 770Ģ0,40,60,80,100,120km(SM),2km(MM) optionalĩ-36VDC power input(2 bit terminal block)Ħ00W surge protection,15KV ESD protectionĭIN-Rail Mounting 1/2 Fiber Ports +1 RS-232/485/422 Serial to Fiber MODEM Notice: Undefined index: isEcom in /home/indiamart/public_html/prod-mdc/IMPaidClnt/TmplViews/d0066/category.php on line 770 Extend RS232 serial RXD, TXD, RTS, CTS, DTR, DSR signal 1.2KM, DB9.Ethernet RJ45lightning protection, 4500V protection capability.BNC video lightning protection, 4500V protection capability.RS485 lightning protection, 4500V protection capability.DB9 serial, RXD, TXD, GND 3 line, 5KV isolation.USB to 4 port RS485/422 converter, USB2.0.USB to 4 port RS232 converter, USB2.0.Industrial RS232 to RS485 converter, port-powered, 2500V isolation.Port-powered RS232 to RS485/422 converter.RS232 to RS485 converter -port powered-DB9.We have Wide range Industrialserial port converters RS232 to RS232 Port Powered Optical Isolator: Brochure with schematic in PDF format / (added 7/02).We are leading in manufacturing and supplier of Serial port Converters in Chennai, Tamilnadu, India. The unit has two RJ11/12 connectors an a pin header for power, common TTL/CMOS TX data and RX data.ĭiscover Circuits – Opto-Isolator Coupler Circuits The unit has jumpers termination, RS232 DTE/DCE selection and, TTL/CMOS operation. The RS422S is a fast Async bi-directional RS232 to RS422 interface converter that will operate at data rates up to 115.2Kbps. Here is a interface from RE Smith Inc, the one below is not isolated. I had to make a high voltage measurement with the PC, so this caution.Īlso use the Max232 if you do no need 1KV Optical Isolation. I made this circuit as i could not risk my PC and had no other components. You can make your own PCB using eagle cad. The Microcontroller will have a +5 and GND use this for the right side of opto. Yes the PC Powers the left side, The supply to the right side is the Microcontroller supply. The Blue line indicates the Optical Isolation, no wires or cooper should cross this line. The the circuit you are referring to is… RS232 with Opto-Isolation
