4 to 20 mA Outputs
The two isolated analog 4-20 mA outputs are available at connector TS2. Pins 1(+) & 2(-) are used for
the analog output associated with the flow rate. Pins 3(+) & 4(-) are used for the 4-20 mA output
associated with the temperature. Both require power for the loop to operate. Refer to Figure 3-3 for
wiring.

Frequency/Alarm Output
The frequency or alarm isolated output is available at connector TS2 pins 5(+) & 6(-). When using the
frequency output, it can be scaled to represent flow rate for totalizing or flow rate indication. Refer to
