COM31XX Serial Isolators for Rail Vehicles

COM31XX Serial Isolators for Rail Vehicles

Product description

The COM31XX Serial Isolators provide galvanic isolation for RS232 and RS485 networks.
 
Galvanic Isolators include:
  • COM3100 - RS232 input and RS232 output
  • COM3110 - RS232 input and RS485 output
  • COM3120 - RS485 input and RS485 output

Product Specification

Model 1:The COM3100 provides a galvanically isolated interface between a RS232 input (PLC Side) and RS232 output (Field Side). The RS232 input (PLC Side) is not galvanically isolated from the power supply. The RS232 output (Field Side) is galvanically isolated from the power supply.
Model 2:The COM3110 provides a galvanically isolated interface between a RS232 input (PLC Side) and RS485 output (Field Side). •The RS232 input (PLC Side) is not galvanically isolated from the power supply •The RS485 output (Field Side) is galvanically isolated from the power supply •The RS485 transmit enable is controlled using the RTS signal on the RS232 input (PLC Side)
Model 3:The COM3120 provides a galvanically isolated interface between a RS485 input (PLC Side) and RS485 output (Field Side). •The RS485 input (PLC Side) is not galvanically isolated from the power supply. •The RS485 output (Field Side) is galvanically isolated from the power supply.
