Can one sensor with a 4- to 20-mA output be connected to two K3NX or K3TS Digital Panel Indicators?


It is possible to connect two Meters. Connect the Meters in parallel, as shown in the following diagram.

The input resistance of the K3NX and K3TS is 10 Ω. When connecting two K3NX or K3TS Process Meters, the sensor's permissible load resistance must be 20 Ω or higher.

Calculating the Maximum Number of Connectable Meters:

Use the following equation to determine how many Meters can be connected.

Sensor's permissible load resistance > Digital Panel Meter's input resistance × Number of Meters
