Encoder Signal Broadcaster
FEATURES
Broadcasts signals from a single encoder to
four independent receivers
Signal processing modules (pulse converter,
integer countdown, anti-dither) can be added
to each output for additional capabilities
Accepts all standard input voltages and
types: single ended, differential and open
collector
Signals are optically isolated for high noise
immunity
Compact package saves installation costs
BEI ELECTRONIC MODULES
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
in
, V
out
= 5
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 included.

CONNECTION INSTRUCTIONS (for Isolated Circuit and Anti-Dither Functions)
Differential Line Driver (See Figure 1)
Encoder signals from 5 VDC to 24 VDC (must
specify the voltage when ordering)
This is the preferred type of encoder output as it
has the best noise immunity. Connect each
encoder signal to its like input (A to A, A/ to A/,
etc).

Connect broadcaster A to optical isolator module input
channel A, B to B and Z to Z. Connect the A/, B/, and
Z/ inputs of the optical isolator to circuit common of
the encoder supply. Single ended operation is limited
to shorter cable runs and is more susceptible to noise.

Encoder NPN (sinking) outputs.
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 positive encoder supply
line. 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.
