Description:
The Allen-Bradley 1747-DPS2 RS-232 DF1 Full-Duplex Port Splitter expands a single RS-232/DF1 full-duplex port on an SLC 500/PLC-5 controller into two separate DF1 communication paths for simultaneous connections to two external devices. It is designed for Rockwell Automation systems using the DF1 protocol, enabling two distinct serial links without reconfiguring the controller port. The unit provides dedicated connections for a DF1 controller port, a network/RS-232 port, and a Prog/HMI port, plus a removable RS-485 terminal for optional remote device support. This port splitter simplifies wiring and expands serial communication capabilities in legacy Allen-Bradley installations.
