A/D
Converter Unit (For Analog Input)
-
Features
Advantages of G type
1. 8 input channels available in a unit
The multi-channel input system reduces the number
of slots.
2. Economical design
Non-insulated interchannel design brings cost
reduction.
Advantages of I type
1. Insulated between channels
Insulated between channels, the unit is not
affected by the potential difference at the input equipment side.
2. 8 input channels available in a single unit
The multi-channel input system reduces the number
of slots used.
3. Voltage/current input is selectable for each
channel
The selection of voltage/current input can be made
by the dip switch.
Advantages of C type
1. Equipped with averaging function
This function reduces the in uence of noise and an
unstable input signal.
2. Scale converting function
This function converts into desired format of data
by changing the full-scale and offset points.
3. Alarm function
It is possible to set the upper and lower limits
and feed back the alarm signal.
4. 4 ranges are available.
The ranges can be changed with the dip switch on
the unit.
