About the 45C202

A 45C202 is a Reliance Electric created Processor Module. Depending on when this module was sold, it could have been also produced by Asea Brown Boveri or Baldor Reliance.

The 45C202 is an R-NET Processor Module that was created for the AutoMate Programmable Logic 30/40 Series.  This card plugs into AutoMate Rack and is connected to the system using a network cable. This module’s main function is to be able to handle all network communication. This allows the AutoMate’s processor to perform other necessary functions. A Multibus is used for data transfers that occur between the processors. Thus, communication does not occur serially. Using other Reliance gateways, the 45C202 can interface other devices to the R-NET. The R-NET network is set up to handle 32 AutoMate PLCs and other devices that need to communicate with each other. The R-NET system is configured using a drop-down coaxial cable.

The 45C202 has 8 status LED indicator lights. These indicator LEDs are labeled READY, XMIT, RECV, COM OK, and there are four COM ER LEDs. This card is contained in a black enclosure that has two mounting feet; one on the top and bottom. There are two holes drilled into the feet and a screw can be used to attach it. The coaxial cable attaches at the bottom of the faceplate.

For more information about the 45C202, please consult the user guides and datasheets originally produced by Reliance Electric. Only skilled professionals should try to attach the 45C202 to an AutoMate Rack to prevent system damage.
