Introducing the CIO-DISO48
Overview: CIO-DISO48 features
The CIO-DISO48 is a 48 channel isolated input interface board. The CIO-DISO48 is designed for applications
where the presence or absence of a high voltage in the range of 5 to 28V (AC/DC) needs to be detected and read
into a computer.
Caution! High voltages are present on the CIO-DISO48 when you have connected high voltage inputs or
outputs to the CIO-DISO48 connector. Use extreme caution! Never handle the CIO-DISO48 when
signals are connected to the board through the connector. Never remove the protective plates from
the CIO-DISO48 unless all input voltages are removed first.
The CIO-DISO48 has 48 individual, optically-isolated (500V) inputs. The state of the inputs may be read from
six read-only, 8-bit registers. The inputs are not polarity sensitive. Either AC voltages (50 to 1000 Hz) or DC
voltages in the range 5V to 28V RMS can be sensed. Each input has a switchable low-pass filter having a time
constant of 5 ms (200 Hz).
