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 VDC. The PCD2.E161 differs from the PCD2.E160 in its shorter input delay,
typically 0.2 ms.
