The CA-IS398x family of isolated octal digital inputs are
CA-IS3980
optimized for industrial 24V digital input applications.All
CA-IS3988
devices can be configured for Type 1, Type 2, or Type 3
inputs with a few external components and each channel
can sink and source current.The isolation channels based
on Chipanalog’s advanced capacitive isolation technology
feature up to 2.5kVRMS isolation rating and ±300kV/μs
