PRODUCT OVERVIEW 
To address diverse applications, the 5B Series includes a family 
of backplanes and mounting cards which provide a complete 
signal conditioning solution. The models 5B03 and 5B04, one 
and two channels cards, allow an economical means to handle a 
few signals.

The backplanes 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.  All 5B Series 
backplanes and sockets require a regulated +5VDC external 
power source.

GENERAL DESCRIPTION 
MODELS 5B03 and 5B04 – For smaller applications, the 
models 5B03 and 5B04 mounting cards are available for one and 
two 5B Series modules respectively. These module cards may be 
clustered for groups of three or more signals. They are DIN rail 
5B03/5B04
compatible using Phoenix Universal Module UM elements.
