1 Introduction
1-10
CJ-series High-speed Counter Units Operation Manual for NJ-series CPU Unit(W492)
Additional Information
• Each Counter Input (A, B, Z) is insulated from the others and from the Digital Inputs. Each Dig-
ital Input is also insulated from the others.
• A noise filter can be configured to 10 kHz or 50 kHz (default) for the Digital Inputs. Every Z-
Input has a defined noise filter of 1 kHz.
• If the 50-kHz noise filter is configured for Digital Inputs, signals of 10
µ
s or longer can be read.
