Wiring The Relay Output - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

WIRING (continued)
Wiring the Relay Output: Switch Tek™ requires 12 36 VDC (30 VDC max. for LZ12 series) power to operate
the sensor and switch the relay. All illustrations below identify a Dry switch state as the normal position of the
relay.
Switching a Normally Open DC Load:
The Red wire connects to Positive (+) of the power
supply and the Black wire connects to Negative ( ).
The LOAD can be attached to either the Green or
White wires. Complete the circuit by connecting the
Green to (+) VDC power or White to ( ) VDC power
(see illustration below).
Sensor Power
[RED & BLK wires] / 36 VDC Max.
5 ±1mA Dry / 22 ±1mA Wet
Switching a Normally Open AC Load:
The Red wire connects to Positive (+) of the DC power
supply and the Black wire connects to Negative ( ).
The LOAD can be attached to the Green wire and the
Hot of the VAC power. Connect the White to the
Neutral of the VAC power (see illustration below).

Switching a Normally Closed DC Load:
The Black wire connects to Positive (+) of the power
supply and the Red wire connects to Negative ( ). The
LOAD can be attached to either the Green or White
wires. Complete the circuit by connecting the Green
to (+) VDC power or White to ( ) VDC power (see
illustration below).
