YS131 is a dual input indicator alarm. One of the two inputs can achieve upper and lower limit, upper and lower limit alarms.

Display and setting function measurement value input display: PV stick chart or trend display digital display measurement values 1 and 2 input are displayed on circuit 1 and 2 screens or trend 1 and 2 screens respectively. Parameter setting: Set on the adjustment screen and engineering screen. The alarm function is suitable for measuring input 1. Alarm types: upper limit, lower limit, upper limit, and lower limit. Alarm settings: -6.3~106.3% (can be set with engineering quantity). Set the alarm setting pointer on the trend screen. The upper and lower limit setting pointers will always display the upper and lower limits on the circuit 1 screen. The lower and upper limit setting pointers will only display when the CHG key is pressed. Lock range: 2%. Alarm display: The ALM indicator light on the front panel is on and yellow. Display on the circuit screen and alarm screen (the detailed content of the alarm is displayed on the alarm screen). When an alarm occurs, the contact output can be set to open or close (4 types of alarms can be set together). When there is a power outage, the contact output can be set to open. The contact output includes 1 upper limit, 1 lower limit, 1 upper limit, and 1 lower limit. The input signal calculation function includes a variable cutoff point. The square root calculation is performed on measurement inputs 1 and 2. It is possible to set the presence or absence of operations and the minimum cutoff point. The setting range of the minimum resection point is 0.0-100%.
