The labelling on the front panel is 4/6 for connecting the channels 4 to 6.

BX8-HD44 44-pin D-Sub socket 4/6 Table

At the 44-pin D-Sub socket 1/6 up to 6 channels can be connected. The labelling on the front panel is 1/6 for connecting the channels 1 to 6. The connections are parallel to the input jacks 1/3 and 4/6. If 1/6 is used, please leave 1/3 and 4/6 opened.

Connection Strain Gage Quarter Bridge

The active strain gage R3 is connected by 3-wire technology.
The internal completion resistors 120 Ohm (QB = Q120), 300 Ohm (QB = Q350) and 1 kOhm (QB = Q1k) are lead through on the connection “QB”.
The internal half bridge R1, R2 is activated with a wire jumper from HB to -Ud.

Connection Strain Gage Half Bridge

The active strain gages R3 and R4 are connected to +Us, +Ud and -Us.
For very long cable lengths the sense lines +Uf and -Uf can be used.
The internal half bridge R1, R2 is activated with a wire jumper from HB to -Ud.

Connection Strain Gage Full Bridge

The active strain gages R1 to R4 are connected on +Us,, -Us, +Ud, -Ud.
For very long cable lengths the sense lines +Uf and -Uf can be used additionally (6-wire technology).

Connection of PT1000

The temperature sensor PT1000 is connected in three-wire technology to the terminals Q1K, UE and GNDE.A
To measure temperature, the input type “PT1000” must be activated once by software.

Connection of thermocouple type K
The + wire of the temperature sensor type K is connected to the +Ud input of one of the analog input channels 1 to 7, the – wire to -Ud.
To measure the absolute temperature with thermocouple K, a PT1000 reference sensor is required, which must be connected to input channel 8.
It should have the same temperature as the type K sensor connector (cold junction compensation). Relative measurement is also possible with type K; in this case you do not need a reference sensor.

Connection of the active sensors
The single-ended voltage signal of active sensors is applied to Ue and GNDE.
Potentiometric sensors can be supplied via +Us. The energy supply for active sensors can be via galvanic isolated voltage VCCIO and GNDIO.

Connection of the TEDS cables for sensors with Transducer Elec. Data sheet
The 1-wire EEPROM memory module located in the sensor or in the sensor connector is connected with two wires: the ground of the EEPROM to GNDE and the signal cable (corresponding to its 3.3V supply cable) at the TEDS connector.
However, TEDS are supported only from firmware version 1.32 on and hardware version 4.0, which are devices that were purchased from about 11/2016.
