 1

⁄4 DIN, NEMA 4X (IP66), Polycarbonate Enclosure 

 User-Friendly Design with Interior LCD Menu 

 Easy to Read with Large, Bright LED Display 

 Quick and Easy to Calibrate 

 Reduces Chemical Consumption

with Cycle-Timed Relays on Controller

 Two Control Relays with Third Relay

for High/Low Alarm on Controller

The PHUCN600 Series multi-parameter controller is a

microprocessor-based controller capable of measuring 

pH, ORP, or conductivity.

There are two displays on the PHUCN600 Series: a bright LED

numeric display with bar graph on the outside front panel, and a

2-line, 16-character LCD display on the inside. The LED readout on

the outside panel can be seen several yards away. The distinctive,

color-coded bar graph will immediately indicate if you are within

the process parameters that you set (green), if the control relays

are on (yellow), and if you are in alarm condition (red). This makes

diagnosing pump and alarm malfunctions easy. All configuration

and control functions are performed on the LCD menu on the

inside front panel.

A universal mounting kit is included for surface, panel, and pipemount applications. The 1

⁄4 DIN enclosure makes panel-mount

cutouts and engineering simple.

Complete and versatile, the PHUTX600 is a 1

⁄4 DIN two-wire

transmitter, which can measure conductivity, pH, or ORP. The

PHUTX600 comes complete with a universal mounting kit for

surface, panel, and pipe-mount applications. The NEMA 4X (IP66)

1

⁄4 DIN enclosure is perfect for stand-alone or panel-mount

operation.

PHUCN600 and PHUTX600 Series are packaged in a rugged

NEMA 4X (IP66) polycarbonate enclosure, making them ideally

suited for heavy-duty applications such as industrial wastewater

neutralization, municipal water and wastewater, pulp and paper,

and process control.

When the PHUCN600 Series is powered up for the first time, 

it will display the meter selection screen where the meter type is

selected. This meter selection screen will only be displayed when

the PHUCN600 Series is powered up for the first time.

After the user selects a meter type, the PHUCN600 Series will

remain set to that meter type until it is changed with the meter

selection menu function in the Utilities menu.

To return the PHUCN600 Series to its factory settings, the user 

re-selects the current meter type from the meter selection menu

function. This will override all setpoints and return all settings to

the factory settings.

The PHUCN600 Series User’s menu has been divided into five

main categories:

• Calibration, used to calibrate the PHUCN600 Series

with the selected sensor

• Utilities, used to manually control or override the outputs

• Setup, used to configure the PHUCN600 Series’ many options

• Diagnostics, used to troubleshoot any problems

• Outputs, used to configure the PHUCN600 Series outputs
