DL305 PLC - Communications and Networking

The DL305 programmable logic controller provides communications and networking capabilities with the following modules and converters:

D3-232-DCU - 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 - 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, so it is not recommended for noisy industrial environments.
