P470 Electronic Pressure Control with Display Product/Technical Bulletin 5
• Minimum required wire insulation rating is 90°C.
• Recommended maximum wire length between the
control and controlled equipment is 50 ft (15.2 m).
• Recommended maximum cable length between
the control and the transducer is 100 ft (30.5 m).
The P470 control uses a P499 transducer to generate
the 0.5–4.5 VDC input signal. The transducer is wired
to the control at the terminal block (TB3) on the
upper-left of the circuit board. See Figure 4, Figure 5,
Figure 6, and Figure 7 when wiring the transducer to
the control. Connect the cable shield to COM on the
TB3 terminal block. Do not connect the other end of the
cable shield to anything.
Use 22 AWG, three-wire, shielded cable to extend the
wiring harness. The recommended maximum length of
shielded cable is 100 ft (30.5 m) between the
transducer and the control. Refer to the
P499 Electronic Pressure Transducer Product/
Technical Bulletin (LIT-12011190) for more information
about the installing and wiring the pressure transducer.
IMPORTANT: No more than four P470 controls
should be wired to a single P499 transducer. Use
a three-wire cable that is 15 ft (4.5 m) or less to
connect the controls. See Figure 7.
