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.
