In this chapter we explain the D/A converter functions of the
TD-SC1 (D/A).
The D/A converter settings only affect TD-SC1 (D/A) models.
The D/A converter allows for analog output that corresponds
to the unit indicator value.
The analog output range is either 0–±10V voltage output or
4–20mA current output. Set the maximum voltage output
between ±1 V and ±10 V in 1V steps using the D/A Maximum
Voltage setting.
Analog output from zero (0 V, 4 mA) to full scale (±10 V, 20 mA)
can be achieved according to the digital values set using D/A
Zero and D/A Full Scale settings.
The zero point and full scale cannot be changed separately for
current output and voltage output.
7-1. D/A output terminals
These can output either voltage or current.
They cannot output both at the same time. Use output mode
commands to set the voltage and current (page 34).

The D/A output is isolated from this unit’s circuits.
For voltage output, connect an external device with a load
resistance of 2 kΩ or more to V-OUT and COM.
For current output, connect an external device with a load
resistance, including cable wiring resistance, of 350 Ω or less to
I-OUT and COM.
NOTE
With static strain display, analog output will be zero.

7-2. D/A Zero
Set the indicator value to output for D/A Zero (0V voltage or
4mA current).
