GF Piping Systems 3-9950-3 Chlorine Controller 2CH DC with 3-9950.393-3 Relay Module and 3-9950.398-2 mA Output

The type 9950-3 Chlorine Controller is a two channel controller that can support two sensors in one instrument. The sensor types supported by the 9950-3 are GF Free Chlorine (FCl), Chlorine Dioxide (ClO2) and pH. The 9950-3 (which is used in the GF Chlorine panels) software, combined with smart electronics connected to the Chlorine sensor (FCl,ClO2) and the pH electrode, delivers a real-time, accurate Chlorine measurement of the application process. Includes improved calibration support by automatically time-stamping the successful single-point calibration of the Chlorine electrode and a two-point calibration of the pH electrode.

An operator can enter the next calibration date and the 9950-3 will display a message and illuminate the red background light to alert the operator when a calibration is due. The new "Chemical Guard" relay mode for free chlorine ensures that the proper dosing of oxidants and pH-adjusting chemicals are delivered safely and accurately. When Chemical Guard mode is selected, the pH control and adjustment is always a priority over dosing oxidizing chemicals whose concentration is pH dependent.

The 9950-3 comes standard with the 3-9950.393-3 Relay Module, comprising four binary inputs and two mechanical relays. Binary input #1 is dedicated to an external flow switch input which enables access to the new relay mode „Chemical Guard" that disables the relays when there is no flow through the system.

The 9950-3 also supports the -1 and -2 relay modules without flow switch or Chemical Guard. The 3-9950-3 also comes standard with four, 4 to 20 mA outputs. The optional 3-9950.395-M Modbus module makes adding the GF Chlorine Controller / panel assembly into a new or existing communication network very simple.
