Introduction

Most industrial computer systems provide standard RS232 serial ports. Though widely accepted, RS232 has limited transmission speed, range, and networking capabilities.

The RS485 standards overcome these limitations by using differential voltage lines for data and control signals.

The C10 makes it easy to build an industrial-grade, long-distance communication system using standard PC hardware, as it converts RS232 signals into isolated RS485 signals without any need to change any hardware or software.

The design of the isolation between the C10 - C12 is different. If the user wants to supply power from the PLC/PC, the C10 or C12 should be used, otherwise, the isolation will be broken.

Frame ground FG

Electronic circuits are constantly prone to electrostatic discharge ESD. 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.
