value=0 with input range 0~1000, output will be 0mA or 0V. When read value=1000, output will be
20mA or 10V.

Alarm Output:
This controller provides twelve types of alarm input selections. When PV is higher or lower than SV,
alarm output will act. Following table consists of twelve alarm output modes.
