Output multipliers / signal splitter for HTL / TTL signals

Output multipliers split incoming signals from incremental encoders before distributing them. They are equipped with three signal inputs (0°, 90° and reference pulse), which are distributed to nine signal outputs (HTL or TTL). Mutual decoupling of the output blocks is optionally possible (OM 3-3Ai).
