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.
