APPLICATION
WATER PROCESSING APPLICATION
A city water company needs to maintain a steady flow of water for their
customer needs. They have an existing 0 to 10 VDC flow transmitter to
measure the water flow. They need to control the water flow, have a high and
low alarm, and keep a recorded chart of the flow for later reference. The Main
Linear DC output of the P48 can be used to control the position of water
output values per the desired flow setpoint value. The P48 relay outputs can
be programmed to give a high flow alarm and a low flow alarm. With the
Second Linear DC output model, the flow measurement to the P48 can be
converted from 0-10 V to 4-20 mA and retransmitted to a 4-20 mA chart
recorder.

MULTIPLE UNIT STACKING
The P48 is designed for close spacing of multiple units. Units can be
stacked either horizontally or vertically. For vertical stacking, install the panel
latch with the screws to the sides of the unit. For horizontal stacking, the panel
latch screws should be at the top and bottom of the unit. The minimum
spacing from center line to center line of units is 1.96" (49.8 mm). This
spacing is the same for vertical or horizontal stacking.
Note: When stacking units, provide adequate panel ventilation to ensure that
the maximum operating temperature range is not exceeded.
