485DRCI Replace Allen-Bradley AIC

USING MODEL 485DRCi IN PLACE OF Allen-Bradley® 1761-NET-AIC Advanced Interface Converter (AIC+)


The B+B SmartWorx Model 485DRCI is an industrial RS-232 t485drci-allenbradley.JPGo RS-422/485 converter. While it is often used in Modbus applications, it may be configured for use in the DH-485 environment as a limited replacement for the 1761-NETAIC. For this application, you may need some additional equipment, as follows:
  1. Allen-Bradley 1761-CBL-AP00 cable (8-pin DIN to 9-pin D-shell), available from your Rockwell Automation distributor.
  2. A DB9 male/male null modem adapter, part number 31D1- 28100 will work, available from B+B SmartWorx.
  3. 24 VDC Power. The 485DRCi must be supplied with external 10 to 48 VDC. B+B SmartWorx Model MDR-20-24 or any industrial power supply will work.

485drci-allenbradley-fig1.JPGThe RS-232 signals on the 485DRCI connect via a DB9 female DCE connector (see Figure 1). This connector will need to be changed to a DTE port using the null modem adapter Model 31D1-28100, available from B+B SmartWorx. Note that there is no provision for powering the 485DRCI via the RS-232 port. Power should be connected via the terminal block. It accepts 10 to 48 VDC.

The 485DRCI has a 5-pin pluggable terminal block with slightly different wiring. You will need to adapt the DH485 Trunk Cable using Tabe 1. Termination is selected via a DIP switch (see Table 2).View 485DRCI Product Details
