Output multipliers

Output multipliers

The output multipliers OM 3-3A and OM 3-3Ai are housed in a module casing with snap-on clamping design for installing on 35 mm DIN rails. They have three signal inputs, which are distributed to nine signal outputs. The basic version offers three signal inputs (0°, 90° and reference pulse) supplied to a respective output block.

Typical fields of application:

  • Multiply encoder signal outputs
  • Mutual decoupling of output blocks (Type OM 3-3Ai)
  • Generate inverted signals
  • Eliminate interference signals
  • Generate additional options
  • Signal level conversion
