Wiring the Transducer
Side-Trak and Auto-Trak transducers require a +15, 0, –15 VDC power
supply and a readout device. Additionally, controllers require a set
point input (0-5 VDC standard, 4-20 mA optional). Transducers are
connected to the power supply, output signal and set point control
through either a
20-pin card-edge connector or 15-pin D-connector. Motor-operated ro-
tary valves use a 10-pin circular connector. Wiring instructions are
given for each type of connector on the following pages. If you are re-
placing another manufacturer’s transducer with a Sierra product, see the
factory-supplied wiring supplement for instructions specific to your in-
stallation.
Recommended Wire Gauges
Using the correct wire gauge for cabling runs to transducers en-
hances system reliability. For cable runs over 150 feet (46 m), con-
sider using a local power supply.
Warning!
Follow National Electric
Code or your local code
safety practices when wir-
ing or connecting this unit
to a power source. Only
qualified personnel should
wire the transducer.
