Product Overview The 6400 is a standalone PC board module used to indicate and control moisture in industrial process air. When used with Newport Scientific’s Hygrosensors, a broad range of moisture conditions can be monitored. Features: Large 4-digit red LED display on the backside of PC board to indicate ...
Sensor Selection The 6400 is designed for exclusive use with Newport Scientific’s narrow range Hygrosensors. Correct sensor selection is important for a successful moisture monitoring system. Use 1200 series for basic moisture measurement, or 1400 series for enhanced accuracy and measurement range.

inside the manifold. If sampling atmospheric air, a sampling vacuum pump may be required at the manifold outlet port to ensure adequate sample air flow through the manifold. The sensor manifold has multiple 10-32 tapped holes for attachment to a panel.
WARNING: As part of the installation, the 6400 must be housed in a suitable electrical enclosure. This enclosure must also serve as a suitable fire enclosure. The PC board is not rated for exposed operation.
0 to 5 volt linear output NOTE FOR 6392N APPLICATIONS: When replacing a legacy 6392N board, connection numbers 1-11 can be duplicated directly to the 6400 terminal block. Only the sensor cable shield needs to be relocated to terminal number 13 on the 6400 board.

Power Wire for power connections must be minimum 22AWG wire rated 300VRMS. Protective ground wire must be minimum the same size as used for power connection. WARNING: An all-pole disconnect device should be installed in line with the power connections to the board to allow safe servicing of the board. Any disconnect used must not interrupt the connection to protective earth ground.

Relay behavior is defined by its relay action setting. NOTE: Relay 2 is present only on 6400-2 models. Sensor Sensor terminal A is the sensor excitation signal. Sensor terminal B is the moisture signal, and terminal C is the temperature signal.
Configuration Configuration options are available through the pushbuttons on the back of the PC board. Two buttons are used to navigate through the menu. Scroll through options using the UP and DOWN buttons, and press both buttons together to select (this is the ENTER command). Enable configuration mode by pressing ENTER.

(such as a high dew point alarm on a dryer), this setting will also indicate an ‘alarm’ when operating power is removed from the 6400 PC board. Indirect action is the default setting in order to be compatible with 6392 installations.

Over Range Action Factory Default: none Options: none No action taken rLY1 Relay 1 alarm rLY2 Relay 2 alarm Sensor over range condition can be indicated by forcing an alarm on either of the control relays. Over range detection only applies to RH or dew point parameters, NOT to air temperature.
This is a warning that the value indicated on the display may not represent the actual process value. When using the 6400 with 1400 Series sensors, the value at which out of range condition occurs will vary with air temperature.
Air Temperature Units Reminder If the process unit is set to AirF or AirC, the display will occasionally flash Air in place of the temperature reading to remind users that the product is configured to indicate air temperature as opposed to dew point. Missing Thermistor If the process unit is set to AirF or AirC without a 1400 Series sensor connected to the board, the display will indicate a missing thermistor condition.
