The BCD input / output status can be checked from bit to bit.
Each input turns green when its ON state is recognized.
Each output turns on when the corresponding button is pressed.

D/A Converter (Option)
A D/A converter is provided for obtaining analog output synchronized with the indicated value of
the F377A.
The analog output ranges are -10 - +10V output and 4 - 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 to -10 - +10V
and 4 - 20mA, and the conversion rate is 2000 times/sec. The maximum voltage output range are
about ±11V, the maximum current output range are about 2.4 - 21.6 mA.
