RS232 RS485 Repeaters R01 - R04 RS232 RS485 Repeaters documentation Data Sheet RS232 RS485 Repeaters (R01 - R04) R01 R02 R03 R04 Features Automatic RS485 direction control ESD protection for the RS232/485 data line Power supply: +12 to +30 VDC or 24 VAC 3000 VDC isolation protection on the RS485 side Transmission speed up to 115200 bps Tx, Rx and power LED indicators RS485 embedded termination 120 ohm Operating temperatures: -40°C to +75°C DIN-rail mounting Compact size - single module format (1M) Dimensions: 90x56.4x17.5 mm 3 years warranty Customization of OEM is welcomed Introduction The R01 provides 3-way optical isolation between both RS485 sides and power supply. It can also be used as a repeater to extend the transmission of an existing network. Additionally, an RS485 system can be expanded beyond the 256 nodes limitation imposed by the standard. The R02 is exactly the same as the R01, except for the isolation range. The R02 has one RS485 side isolation. The R03 separator module provides a complete full-duplex, 3-way electrical isolation channel between two RS232 devices. This isolation is an important consideration if a system uses different power sources, has noisy signals or must operate at different ground potentials. The R04 is exactly the same as the R03, except for the isolation range. The R04 has one RS232 side isolation.

Redisage Electronics modules feature a design for the frame ground terminal block FG. The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable. Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD. Frame Ground FG connection reference drawing is provided below. If earth ground is not available FG can be left floating or it can be connected with the power supply GND.
