Need help selecting a PLC family?
Use our configuration tool to configure and order.

PLC communication is a vital component of any control system. With the many networking options available, PLC systems need to have adequate ports and protocols. The DirectLOGIC 305 CPUs have built-in serial ports; optional modules can provide protocol conversions or additional communication ports. Not intended for new system development as only a limited number of products are available.

DL305 PLC - Communications and Networking

D3-232-DCU (retired) - Attaches to the front of the DL305 CPU to provide RS232C programming port connection for use with personal computers, operator interfaces, etc.
FA-ISOCON - Universal, isolated RS232C to RS422/ RS485 converter.
Switch selectable for ANTE (Automatic Network Transmitter Enable) or RTS/CTS handshaking, works with all DirectLogic PLC families and virtually any serial device. Isolation reduces network data problems caused by noisy environments. Power directly from the 5 V pins on most DirectLogic CPU ports, from a PLC base 24 VDC power supply, or from an external power supply. Cables and connectors to most COM ports (RJ12, DB9-female, DB25-male) provided. Integral DIN rail clamp or can be panel mounted. Manual included with product.
FA-UNICON (retired) - In-line, DB25, RS232C to RS422/ RS485 converter.
Connectors to connect a DirectLOGIC RJ11/ RJ12 RS232C port to a DB25 female RS422/ RS485 connector. Power directly from the PLC base 24 VDC supply or an external power supply. Connection to a PC RS232 COM port requires a custom cable. A pin 4-20 jumper is required on the FA-UNICON for DB9.
NOTE:The FA-UNICON provides no signal isolation.
