D/A converter output
A D/A converter is provided for obtaining analog output synchronized with the indicated value of the
TM380. The analog output ranges are -10 to +10V output and 4 to 20mA constant-current output.
By using the D/A zero setting and D/A full scale setting functions, analog output can be obtained
between zero (0V, 4mA) and full scale (10V, 20mA) with respect to the predetermined digital value.
The output circuit and the main unit circuit are isolated.
The resolution is 1/10000 with respect to the ranges of -10 to +10V and of 4 to 20mA, and the
conversion speed is 8000 times per second.
The maximum voltage output range are about ±11V, the maximum current output range are about
2.4 to 21.6 mA.

Connection
For the output terminals of the D/A converter option, a cage clamp type terminal block is used.
Make connections by the following procedure.
Connecting to cage clamp terminal block
1.
Strip the casing 0.2in (6mm) on the cable to be
connected.
Twist the bare wire to fit the terminal hole.
2.
Insert the supplied screwdriver into the right hole
and lift right.
3.
Insert the twisted wires into the left hole.
4.
Pull the screwdriver out from the upper hole.
5.
Make sure cable is clamped securely and does
not come out with a slight tug.
