To address diverse applications, the 5B02 is a backplane which provides a complete signal conditioning solution. Two 16-channel (models 5B01 and 5B02) and two 8-channel backplanes (models 5B08 and 5B08-MUX) can be mounted in a 19" x 3.5" panel space, providing different system configuration options.

The 5B02 16-channel backplane incorporates an input and output bus which takes advantage of the internal series output switches in the input modules and the track-and-hold in the output modules. Designers integrating the 5B02 into a measurement and control system do not need external multiplexers and can use a single digital to analog or analog to digital converter to serve numerous output or input channels.

All backplanes and sockets provide four screw terminals per channel for all field connections. These connections satisfy all transducer inputs, process current outputs and provide transducer excitation when necessary. A cold junction temperature sensor (model AC1361) sensor is also supplied on each channel to accommodate thermocouple input modules. A pair of pin sockets permits installation of the AC1362 current sensing resistor used with the 5B32 current input module. On all 16-channel and 8-channel backplanes, a 26-pin system interface connector provides high level I/O for all channels. All 5B Series backplanes and sockets require a regulated +5 Vdc external power source.
