BEI ELECTRONIC MODULES
Encoder Signal Broadcaster
The BROADCASTER accepts standard incremental encoder inputs, (two channels in quadrature plus an
index and complements) and can broadcast up to four encoder signals to four independent devices. Each
of the broadcast signals is optically isolated eliminating ground loops. This compact package also allows
for signal processing options, such as anti-dither filter, integer countdown or pulse and direction outputs, to
be incorporated into each of the four broadcast signals independently. The broadcaster is ideal for driving
multiple receivers from a single encoder in applications like electronic line shafting or synchronization of
multiple devices to a single operation.
The module accepts signals of 5, 12-15 and 24 VDC and provides three output options: V
V or NPN open collector. The compact package mounts to standard EN 50 022 35mm X 7.5mm DIN rail
and is 142mm wide, 78mm deep and 45mm above the DIN rail. A 155mm section of DIN rail is includ

Connect encoder output A to optical isolator module
input A/, B to B/ and Z to Z/. Connect the A, B, and Z
inputs of the broadcaster to the auxiliary output terminal
on the broadcaster module. This connection results in a
logic inversion within the broadcaster module. To
compensate for the logic reversal, swap A for A/, B for
B/, and Z for Z/ at the broadcaster outputs.
