P470 Electronic Pressure Control with Display
Description
The P470 Electronic Pressure Control with
Display is a single-stage, On/Off, electronic
pressure control with a single-pole,
double-throw (SPDT) output relay. The control
may be field set to operate in one of
three pressure ranges (0 to 100 psi, 0 to
500 psi, or 50 to 750 psi), as either an
open high or open low control.
The P470 Control features a large LCD that
displays the sensed pressure and other
system-status indicators, as well as the
adjustable setpoints in the programming
mode. The P470 Control has a lockable,
three-button touchpad for adjusting setpoints,
and a front-panel LED that indicates the output
relay status.
The P470 Control uses a P499 Electronic
Pressure Transducer in conjunction with a
WHA-PDK3 Wiring Harness to sense system
pressure. This arrangement virtually
eliminates the chance of a refrigerant leak
because there are no capillaries or bellows to
break or fail.
Refer to the P470 Electronic Pressure Control
with Display Product Bulletin (LIT-125528) for
important product application information.
Selection Chart
Note: P470 Controls do not include a transducer or wiring harness. P499 Transducer and wiring harness must be purchased separately.
Transducer must be matched to the selected pressure range.
