Digital input modules
5.2.2 PCD2.E160/161, 16 digital inputs, ribbon cable connector
Application
Low-cost input module for source or sink operation with 16 inputs, electrically
connected. Suitable for most electronic and electromechanical switching elements
at 24 V
DC
. The PCD2.E161 differs from the PCD2.E160 in its shorter input delay,
typically 0.2 ms.
