Application
With the input a status can be monitored, the input can be configured by controller or
configuration tools as follows:
l “Status“ input or “Alarm“ input
l Lead monitoring for open line or open line and short circuit
l When inputting status, according to different status of contact, can be set as
follows:
- Normal mode: normally open input
