Analog I/O Terminals Section 4-8
Note The DRT1-AD04H has insulation between the inputs, so there is no need for
the user to be concerned with the internal circuitry.

Wiring: DRT1-AD04 and
DRT1-AD04 H (Common)
Connect the power supply and inputs (voltage input or current input) to the
Analog Input Terminal’s terminal block as shown in the following diagram.
Do not connect the shield when using shielded cables for the inputs.
Input Ranges and
Converted Data
The Analog Input Terminal converts analog input data to digital values. The
digital values depend on the input signal ranges, as shown in the following
diagrams.
Note When the input exceeds the specified range, the AD conversion data will be
fixed at either the lower limit or upper limit.
