Primeda RS485 Data Extenders -1 Bidirectional RS485 to Fiber Optic up to 20Km(12.4mi) | Transmitter and Receiver | for Access Control System

Overview: the unit is a RS-485 interface fiber MODEM with asynchronous transmission half-duplex transparent protocol, which is the best for connecting remote terminal unit (RTU) to host (HOST) or distributed data acquisition system (SCADA) controller select. The product uses optical fiber as the transmission medium to improve the transmission performance of the system and effectively avoid the threats to communication equipment such as lightning strikes, surges and electromagnetic interference in harsh environments. Specification: 1.Complies with EIA RS-485 standard. 2.RS-485 signal T+ T- (corresponding to industrial terminal pin 1+, 2-) 3.Working mode Asynchronous work, point to point. 4.Direction control adopts data flow automatic control technology to automatically determine and control the data transmission direction. 5.Baud rate 0-120Kbps, automatic detection of signal rate. 6.Fiber wavelength Multimode 850nm, single mode 1310nm. 7.Electrical port transmission distance RS-485 port 200 meters max. 8.Transmission distance 0-500meters for multi-mode, 0-20kilometers for single-mode (40Km/80km/60km/100km is customizable). 9.Interface protection 600W surge protection, 1500V electrostatic protection. Package contents: 1x RS485 data Transmitter. 1x RS485 data Receiver. 1x SC/SC 3M singlemode fiber patch cord. 2 x power supply adapter ( US standard plug). 1 x User manual
