Wiring as a P‐Channel or N‐Channel output:
The Thermo‐Flo™ can be substituted for either a P‐Channel
(PNP, Sourcing) output or N‐Channel (NPN, sinking) output.
Normally Open DC Load as a P‐Channel Output (Open during Flow, Closed during No‐Flow):
To wire as a NO P‐Channel output follow the
directions below. The Red Wire connects to Positive
(+) of the power supply and the Black wire connects
to Negative (‐). The Green wire is jumping to the Red
wire while the White wire is connected to the LOAD.
Jumper the LOAD back to the Negative (‐) to complete
the circuit.
Normally Closed DC Load as a P‐Channel Output (Closed during Flow, Open during No‐Flow):
To wire as a NC P‐Channel output, follow the
directions below. The Black wire connects to Positive
(+) of the power supply and the Red wire connects to
Negative (‐). The Green wire is jumping to the Black
wire while the White wire is connected to the LOAD.
Jumper the LOAD back to the Negative (‐) to complete
the circuit.
Normally Open DC Load as a N‐Channel Output (Open during Flow, Closed during No‐Flow):
To wire as a NO N‐Channel output, follow the
directions below. The Red wire connects to Positive
(+) of the power supply and the Black wire connects
to Negative (‐). The white wire is jumping to the Black
wire while the Green wire is connected to the LOAD.
Jumper the LOAD back to the Positive (+) to complete
the circuit.
Normally Closed DC Load as a N‐Channel Output (Closed during Flow, Open during No‐Flow):
To wire as a NC N‐Channel output, follow the
directions below. The Black wire connects to Positive
(+) of the directions below. The Black Wire connects
to Negative (‐). The white wire is jumping to the Red
wire while the White wire is connected to the LOAD.
Jumper the LOAD back to Positive (+) to complete the
circuit.
For all Sensor Wiring diagrams above:
Sensor Power: Red and Black Wires (36 VDC Max.)
Relay Rating: Green and White Wires (60VA, 1A Max.)
