Digital Temperature Indicating Controller |
|
ACN-200 |
|
Potentiometer analog setting
|
As easy to operate as our traditional model, the ACN-100 series.
Can set and change the SV easily using an analog setting unit (potentiometer). |
|
The ACN-220 (PD control) comes with an Auto-reset function.
|
|
Control action can be changed with the DIP switch.
|
Control action: PD or ON/OFF control is selectable with the DIP switch.
|
|
Model |
(*1) Control Action and Alarm Type can be selected with the DIP switch. When shipped, user specified
Control Action and Alarm Type have been set on the controller.
(*2) For the Alarm Action with Standby, “H” is attached to the end of the model name. |

Alarm Function |
Alarm output |
The Alarm action point is set as a ±deviation from SV (except Process alarm). When the PV is out of the range, the alarm output turns ON or OFF (in the case of High/Low Limit Range alarm).
If the Alarm Function is specified, one type can be selected with the DIP switch: No Alarm Action, High Limit alarm, High Limit with Standby alarm, Low Limit alarm, Low Limit with Standby alarm, High/Low Limits alarm, High/Low Limits with Standby alarm, High/Low Limit Range alarm, Process High alarm and Process Low alarm.

Alarm output: Setting by the deviation from the SV (except process alarm). If the input goes outside the range,
the output turns ON or OFF (in the case of High/Low limit range alarm).
Alarm type: If any alarm type (except no alarm action) is specified, the alarm type can be changed with the DIP
switch. (Default: Customer specified alarm type)
