When DC input, –1999 … 9999
(Decimal point place follows the selection.)
Output limiter
: 0 … 100 % (In the case of Current output, –5 … 105 %)
ON/OFF action
Hysteresis setting range :
When thermocouple or RTD input, 0.1 … 100.0 °C (°F)
When DC input, 1 … 1000 (Decimal point place follows the selection.)
Alarm 1 (A1) output
The alarm action point is set by ±deviation to main setting (except Process value alarm).
[When the alarm action is set as energized]
When the input exceeds the range, the output turns ON or OFF
(in the case of High/Low limit range alarm).
[When the alarm action is set as deenergized]
The output acts conversely.
One of the alarms can be selected by rotary switch and DIP switch from 14
types of alarm; High limit alarm, Low limit alarm, High/Low limits alarm,
High/Low limit range alarm, Process high alarm and Process low alarm,
and the standby function is applied to them respectively, as well as
No alarm and Pattern end output.
