Input Specifications
Note
1. The Counter Inputs (A, B, Z) are insulated from each other and from the Digital
Inputs. The Digital Inputs are also insulated from each other. All Counter Inputs
and Digital Inputs are reverse polarity protected and insulated from the I/O-bus.
2. For every pair of Digital Inputs (I0 & I1, I2 & I3) a noise filter can be configured
(10 kHz or 50 kHz (default)). Every Z-Input has a defined noise filter of 1 kHz.
